WEBSITES http://www.legislation.govt.nz/ www.education.govt.nz/ http://www.telepermit.co.nz/PtcSpecs.html LATEST REVISIONS The users of this document should ensure that their copies of the above-mentioned New Zealand Standards and the New Zealand Building Code are the latest revisions. Amendments to referenced New Zealand and Joint Australian/New Zealand Standards can be found on http://www.standards.co.nz.
FOREWORD The educational environment provides one of the most challenging frameworks for the operation of comprehensive structured information and communication technology (ICT) infrastructure solutions. It has exceptionally high requirements for reliability, fault-tolerance and service availability that exceed many other similar sized operating environments. Educational providers are frequently at the leading edge of the technology and application lifecycle with teaching systems often involving new and innovative applications, extensive use of graphical content, monitoring, and reviewing functions. They are also much more likely to involve the use of complementary technologies including wireless and cabled monitoring systems, audio-visual applications, presentation applications, multi-media content, metering and control requirements and collaborative developments than their commercial or government counterparts. The modern school infrastructure must address not only the standard applications of telephony and data connectivity, but must also support the unique requirements of heavy burst-oriented network traffic requirements over relatively shorter periods associated with educational systems, extensive use of multi-media technologies, and both wired and wireless networking. The goal of this Ministry of Education document, Information and Communications Technology (ICT) Cabling Infrastructure: Policy and Standards for Schools v5.0 is to provide a reference document for cost effective design and construction of cabling infrastructure for all facilities in New Zealand Schools. It has been prepared to outline the minimum standards required to ensure consistency and compatibility of all new and existing Ministry of Education schools Generic Cabling Systems (GCS) and network infrastructure systems. This document provides the technical standards and guidelines that shall be followed for the design and technical performance of any ICT cabling infrastructure in facilities owned by Ministry of Education schools is installed, maintained, certified and managed. It is updated regularly as Standards, school requirements and Ministry policy change. Prior to using this document the user should confirm that they have the latest version. The latest version of the document may be obtained from www.education.govt.nz/
Purpose The document shall be used by schools and other organisations which participate in the design, installation, and operation of information and communications technology infrastructure and cabling systems for New Zealand schools. The document addresses information technology infrastructure in new schools, and is to be applied to existing schools planning significant installations, upgrades, and modifications to existing infrastructure. This document provides guidance on minimum technical standards in the following areas: a) Technical requirements for cabling systems b) Product selection c) Design, installation and testing d) Labelling, administration and documentation.
Document sponsor This document has been developed and is controlled by the Ministry of Education. All queries, errors, omissions or suggestions are to be directed to: The Group Manager Business Services Education Infrastructure Service PO Box 1666 Wellington 6140 Email: [email protected]
Outcome statement By using this document and relative standards, designers and installers will successfully meet the Ministry of Education minimum standards for the safety, design, installation and support of generic and structured cabling systems and information and communications technology environments that New Zealand schools manage and operate.

1. USING THIS DOCUMENT
1.1 Interpretation of this document 1.1.1 Interpretation For the purposes of this document, use the key words "must", "must not", "required", "shall", "shall not", "should", "should not", "recommended", "not recommended", "may", and "optional". These are to be interpreted as described in RFC2119. RFC 2119 gives the following definitions: 1. must This word, or the terms "required" or "shall", mean that the definition is an absolute
requirement of the specification and mandatory.
2. must not This phrase, or the phrase "shall not", mean that the definition is an absolute prohibition
of the specification.
3. should This word, or the adjective "recommended", mean that there may exist valid reasons in
particular circumstances to ignore a particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
4. should not This phrase, or the phrase "not recommended" mean that there may exist valid
reasons in particular circumstances when the particular behavior is acceptable or even useful, but
the full implications should be understood and the case carefully weighed before implementing any
behavior described with this label.
5. may This word, or the adjective "optional", mean that an item is truly optional. One vendor/ supplier
may choose to include the item because a particular marketplace requires it or because the vendor/
supplier feels that it enhances the product while another vendor/ supplier may omit the same item.
An implementation which does not include a particular option must be prepared to interoperate with
another implementation which does include the option, though perhaps with reduced functionality.
In the same vein an implementation which does include a particular option must be prepared to
interoperate with another implementation which does not include the option (except, of course, for
the feature the option provides.)
1.1.2 Scope of this document This document addresses the following areas: a) Generic Cabling System (GCS) comprised of balanced copper cabling and optical
fibre for use in New Zealand schools
b) Cable pathways and equipment spaces including equipment rooms, distribution
spaces and equipment mounting
c) Cabling for wireless networking systems.
1.1.3 Criteria for use All school Information and Communications Technology (ICT) installation and upgrade work shall be in accordance with this document. It is a requirement of the Ministry that all schools, designers and installers of networks for schools shall use this document, in order to allow the school to fully participate in the e-learning environment and protect the investment in the ICT cabled infrastructure.
13
In addition to this document, the designer and installer should refer to other sources for detailed design and installation guidance, such as relevant mandatory legislation, publications outlined in this document, and manufacturer installation guidelines.
Application of this document 1.2.1 Regulations, codes, and Standards All cabling system works are to be carried out in accordance with the regulations, codes, and Standards listed at the beginning of this document. Where New Zealand and international Standards are referenced in this document the application of the Standard shall be, unless specifically stated elsewhere to the contrary, to the latest edition and amendments available on the date 30 calendar days prior to the issue of any request, quote, tender or proposal. Where design and construction of a new site spans multiple stages, each new stage shall comply with the requirements of this clause. Where design and tender is completed as a single stage, but construction spans multiple stages, the standard to which the first stage was initially designed shall remain the same throughout the rest of the build programme, unless a variation and instruction is issued to change by the Ministry of Education or their Project Manager. Where specifications or Standards, or any other references in this document refer in turn to other specifications, Standards or documents whether whole or in part, the strictest of those consequential references shall apply to this specification as if they were completely contained in the original reference. Regulatory requirements and Codes of Practice – cabling Other than for compliance with the Electrical Regulations and relevant New Zealand Codes of Practice, there are no regulatory requirements for telecommunications cabling components, design practices, or installation practices in New Zealand. The Telecommunications ACT 1987 gives Telecom and any other Network Operators the right to refuse connection or to disconnect unsatisfactory cabling and components from their network. For cabling connected to the national telecommunication network, compliance with Telecom PTC specifications is a contractual requirement. 1.2.2 Installation specific standards and requirements The designer and installer shall conform to all the requirements of this Standard. Designer and installer note: Where a school has site specific standards and requirements, for example product type or labelling schemes, and it is a) cost efficient; and b) does not have a material impact on the technical aspects of meeting this Standard, then these shall be followed if written agreement from the school and the Ministry is received.
14
1.2.3 Variation from this document Compliance to the requirements of this document may, under some circumstances, not be practical, or cost effective, or an alternative solution may exist that better suits the conditions on site. The designer and installer are advised that, in the event that compliance to this document cannot be met, before undertaking the non-compliant works the designer or installer is to obtain written approval for a variation from: Director – EIS Business Services Business Services Education Infrastructure Service PO Box 1666 Wellington 6140 Email: [email protected] 1.2.4 Conflicts If a conflict exists between the Standards or with the Scope of Works then the installer shall notify the Project Manager or their representative of any conflicts and seek clarification prior to continuation. In general the order of precedence shall be: a) Statutory Codes and Regulations b) The Ministry of Education publication ICT Cabling Infrastructure: Policy and
Standards for Schools (this document) c) Standards and specifications within the tender or contract d) Referenced New Zealand and International Standards In situations where tender specific Standards, specifications, or both, exceed Ministry requirements, these shall take precedence. Where reference is made to a specification, the latest release available on the date 30 calendar days prior to the issue of any request, quote, tender or proposal shall apply. Conflicts in requirements or requests for variation from published documents that are identified by Schools, consultants, designers, tenderers, or installers shall be notified in writing to: Director – EIS Business Services Business Services Education Infrastructure Service PO Box 1666 Wellington 6140 Email: [email protected] Written confirmation from the Ministry is to be received before resolution.

2. STRUCTURED CABLING SYSTEMS: OVERVIEW
2.1 ICT cabling background The Information and Communications Technology (ICT) cabling system plays a critical role in telecommunications systems, providing the physical link between sources and destinations of information. Data, voice, video and control signals are transmitted over this infrastructure linking devices across the hall, throughout a building or across several buildings. Cabling systems range in size from small and simple, linking just a few nodes, to large and complex, linking several buildings with tens of thousands of nodes. The cabling system provides the physical link between active network equipment such as routers and switches, and the terminal equipment such as computers and telephones. New Generic Cabling Systems (GCS) are typically comprised of copper and optical fibre cabling. To facilitate the day-to-day operations of a normal school environment, a cabling system must enable the user to make additions, moves and changes, wherever and whenever necessary. Furthermore, the GCS must also be flexible and provide the capability to carry a wide variety of applications – from high-speed local area network (LAN) applications to voice and low speed data. As data throughput and transmission speeds continue to grow, greater demands are being placed on the ICT cabling infrastructure. Gigabit Ethernet, and other high bandwidth services, use “parallel transmission schemes” to transmit signals simultaneously over multiple copper pairs instead of one pair. Delivery of these new services requires increased performance from cabling plant.
2.2 Generic Cabling System (GCS) Generic cabling is a structured telecommunications cabling system capable of supporting a wide range of standardised applications such as voice, video and data. Cabling equipment manufacturers shall be Ministry approved and offer a minimum link performance warranty of 20 years if the installation uses approved components that are installed by an installer certified or accredited by the manufacturer. In the case of work undertaken to change or expand an existing cabling installation the following requirements shall be applied1: a) The new equipment shall be specified to ensure all existing warranties and
system performance are maintained or enhanced. b) The new equipment shall be matched as closely as possible to the existing
equipment unless a more up to date and cost effective solution is available or
1 This applies specifically to existing buildings and does not apply to new buildings on the same site
20
such matching would conflict with occupational health and safety requirements or mandatory standards.
c) The number of differing types of equipment installed throughout a site shall be kept to a minimum.
In the case of cabling for new buildings added to a school, the cabling system shall comply with the requirements of this document unless such compliance would create compatibility or performance issues.
2.3 General design requirements Generic cabling systems are generally intended to serve for a long period of time. However, it is likely that transmission system requirements will change during the life of the cabling system. It is for this reason Cat 6 UTP and OM3 fibre in the previous standard (V4.0) shall now be superseded by Cat 6A shielded cabling (F/UTP or S/FTP) and OS2 fibre in this standard. For this reason it is important that the cabling system is designed to be flexible and scalable, to ensure longevity and accommodate future increased bandwidth requirements. This is particularly important where cabling is installed underground or in other locations where upgrades to plant can be expensive and disruptive. If the Ministry approved certified installer is not furnished with a design for switching and wireless by an independent ICT Switching and Wireless design specialist and have been engaged by the school or any other third party to design or install cabling at the school, then they shall ensure that they meet all the requirements of the following standards: https://www.education.govt.nz/assets/Documents/School/Running-a-school/Technology-in-schools/technical-info/MoE-Information-and-Communications-Technology-ICT-Switching-Infrastruc....pdf And https://www.education.govt.nz/assets/Documents/School/Running-a-school/Technology-in-schools/technical-info/MoE-Information-and-Communications-Technology-ICT-Wireless-LAN-Infrast....pdf All school ICT installation and upgrade work shall be in accordance with these documents. The Ministry requires that all schools, designers and installers of network and wireless systems in schools shall use these documents, in order to allow the school to fully participate in the e-learning environment and protect the investment in switching and wireless systems.
21
2.3.1 Switching and Wireless System Works The scope of work for the provision of switching and wireless systems and equipment in schools typically includes design, supply, installation, testing, commissioning, and documentation. Any new design shall include an overarching document that covers all 5 stages of Safety in Design (SiDs).
2.3.2 Switching and Wireless Systems: Design Standards General Because of the diversity of school sizes, building layouts, and networking requirements, a range of common switching and wireless system architectures are described. Schools are encouraged to discuss their requirements with an independent designer or consultant prior to purchasing hardware. Determining Location of Wireless Access Points There are two methods for designing a WLAN solution, Predictive RF planning and Physical RF Mapping (Site Survey). Predictive allows a designer to provide a school with costs to deploy a wireless solution to meet the brief without a site visit or for buildings that are not yet constructed. Schools shall always request that any plan include at a minimum a predictive RF coverage map. This can then be tuned onsite with physical RF mapping, also referred to as a site survey. The design, installation and configuration of any network switching and wireless shall be completed by a suitably qualified person.
2.3.3 Switching and Wireless System: Installation Practices General The switching and wireless systems supplier/reseller or appropriately qualified designate that can supply all labour, materials and equipment required for installing, testing and commissioning the network. The supplier or designate shall include a copy of all relevant specifications, compliance reports, documentation and diagrams including the switch and wireless IP address assignments for installation in an “as-built” document manual. Safety PoE switching shall not exceed the designed remote powering capability of the cabling system, If PoE switches are installed in a cabinet for remote powering purposes and no remote powering label exists on the cabinet, then the network switch supplier or approved ICT Contractor when installing any new network switching shall install a warning label on the front, back and sides of the cabinet detailing the maximum permitted remote powering as per the cabling manufacturer’s warranty and recommendation. All ICT contractors and Integrators installing PoE switching or patching fibre optic cabling shall have completed the Ministry of Education’s ICT Cabling Infrastructure Policy and Standards for Schools approved contractors course to demonstrate competency in understanding the safety requirements for working with fibre optic
22
cabling, Remote powered systems and any network providing connectivity to safety devices e.g. Lockdown, CCTV, Panic Alarms (Security Intrusion Detection Systems) etc. The contractor’s certificate shall remain valid for a period of two years from passing the exam. All contractors maintaining a network containing fibre optic cabling and interfaces shall ensure all locations containing this equipment have compliant labelling installed.
2.3.4 Switching and Wireless Systems: Documentation The contractor that has supplied and installed the WLAN and switching equipment shall produce both pre and post installation, a full network diagram with IP addresses and VLAN information detailed. Also required, within one week of the site visit, is a commissioning report and excel spreadsheet containing equipment serial numbers and a completed network switch and wireless site sign-off form from the school stating that the network and all existing services have been tested and are operational. It shall be the contractor’s responsibility to demonstrate operational status to the schools authorised point of contact. All WAPs installed shall be clearly and logically labelled and all newly installed WAPs shall be documented with evidential photographs indicating position within a designated space prior to the installer completing the commissioning. Refer to the Wireless standard for all commissioning requirements.

In addition, all works involving product and equipment shall be carried out in accordance with the manufacturer’s product guidelines, instruction sheets and specifications. See 0 for more information. In all cases where Standards, documents and publications are referenced in this document the application of the Standards, documents and publication shall be, unless specifically stated elsewhere to the contrary, to the latest edition and amendments available on the date 30 calendar days prior to the issue of any request, quote, tender, proposal or scope document. If a conflict exists between the standards other documents, publications or scope of works, the installer shall notify the Ministry of Education or its representatives of any conflicts and seek clarification prior to continuation. It is the installer’s responsibility to obtain the latest editions of and familiarise themselves with these documents and publications.
3.4 Security clearance and Police vetting The Education Act requires that every installer, employee of an installer, or subcontractor engaged by an installer who has, or is likely to have, unsupervised access to students at the school or children during normal school hours or service opening hours must be Police vetted.
24
Normal school hours are defined as the hours that the school is open for instruction. Police vetting shall be obtained before a person who is required to be vetted has, or is likely to have, unsupervised access to students or children. A Police vet is valid for up to 3 years – after 3 years a new Police vet must be
obtained and access approved/declined
A Ministry of Justice vet is not an acceptable substitute for a Police vet as it is less
thorough and does not meet the requirements of the Education Act
Because property-related projects do not involve working directly with children,
Police vetting requirements of the Education Act 1989 apply, not the Vulnerable
Children Act 2014
Many schools will also wish to induct visitors onto the site using the normal business practice of signing visitors into the school when they arrive and signing them out as they leave.

The maximum channel length is 100 metres for Class D, Class E and Class EA. The cable and components used within balanced cabling systems are classified according to category. Category 5 components collectively provide Class D performance while Cat 6 components collectively provide Class E performance. Category 6A components collectively provides Class EA. AS/NZS 11801-1 defines the maximum channel lengths supported by optical fibre applications for both multimode and single-mode optical fibre. These maximum distances over which supported applications shall operate are detailed in the Table 1 under section 4.6 Cable lengths, details the applicable wavelengths, distances and supported applications.
The defined optical fibre types are multimode 50/125m (OM3, OM4, OM5) and single-mode (OS1a - indoor, OS2 - outdoor). The M in this case signifies multimode while the S signifies single-mode. OM1 and OM2 will only be informative in the new AS/NZS 11801-1 standard.

4.5 Category 6 and 6A (Cat 6A) F/UTP or F/STP cable and connecting hardware
Cat 6 and Cat 6A cables used within horizontal cabling subsystems, or as work cords, shall comply with Clause 9 of AS/NZS 11801-1. In the event that multiple signals share a cable the additional performance requirements of Clause 9.3 of AS/NZS 11801-1 shall be met. Cat 6 and Cat 6A connecting hardware used within horizontal cabling subsystems shall comply with Clause 10 of AS/NZS 11801-1. Cat 6 and CAT6A horizontal cabling shall be terminated with modular 8-pin (RJ45) outlets using the T568A arrangement. Cat 6 and CAT6A backbone balanced cabling shall be generally terminated with modular 8-pin (RJ45) outlets using the T568A arrangement. However, insulation displacement (IDC) punch-down blocks may be used to terminate outdoor balanced cables used within the voice backbone. 4.5.1 MPTL Distributed building services, which includes CCTV, BMS controllers, Video intercoms etc., shall be terminated as MPTL assemblies, where the cabling cannot be terminated in a standard 8P8C modular jack. The connectors shall be a tested as per AS/NZS 11801-1, Annex B, if no specific IEC standard testing is required by the manufacturer, to ensure the connectors allows for equivalent mechanical and environmental performance requirements, stated under the AS/NZS 11801-1. The following IEC standards are accepted: IEC 60603-7 (for unscreened cabling) and IEC 60603-7-1 (for screened cabling). The MPTL connectors shall also comply with Table B.1 (Standards for solderless connectors). Cable re-termination into a free MPTL is not allowed under schedule B.4 or B.6 of the AS/NZS 11801-1. Re-termination is only allowed for fixed MPTL units. The introduction of a MPTL shall not introduce more than 2.5 Ohms with the initial termination and more than 5 Ohms after the MPTL has been allowed to settle. The introduction of a MPTL unit shall not cause the overall generic cable channel to exceed 100m, unless the applications allows for it i.e. BMS sensors. MPTL assemblies shall not be implemented with ES3 applications. Field terminated assemblies will not be allowed to ensure that the cabling channel and permanent link will be covered under cabling warranty. IDC assemblies are allowed but not insulation piercing methodology (eg. Vampire tap). Any MPTL connections deployed as a part or the overall cabling solution shall be tested and warrantied as per the requirements of this standard.

Figure 2: Conceptual cabling layout
The Structured Cabling System within a school will often combine the Building Distributor (BD) or Campus Distributor (CD) (Distributor 3 and Distributor 4 ) and Floor Distributor (FD) (Distributor 2 and 1) functions. A conceptual layout that could be typically applied at a school is illustrated Figure 2 above. The lead-in cable providing the interface to carrier services will normally be located at the building that is closest to the carrier infrastructure.
4.8 Aesthetic design In all cases the GCS shall be designed and installed in a manner that is suitable for the building and not in conflict with the environment at the particular school. 4.8.1 Heritage buildings Many schools contain buildings that have significant historical or cultural significance. Modification on work within these buildings may be difficult and the amount and nature of any refurbishment may be subject to specific controls and restrictions. Designers and installers are required to ensure that in the proposed construction activities do not compromise the restrictions imposed in these buildings. See APPENDIX A – HERITAGE SITES for more information.
44
4.8.2 Exposed cabling The designer is expected to minimise the use of exposed conduit and capping and overhead connections. Where possible all cabling and cable pathways, including pits and external conduits, should be placed as unobtrusively as possible so as to be hidden from view and not attract attention. It is expected that where service pathways are provided in a school campus (walkway cavities are a perfect example), they will be used to distribute ICT Cabling Infrastructure around that campus – If for any reason this may not be practicable, then written agreement from BOTH the School’s authorised representative and the School SPA will be needed. When it is not possible to completely hide the cable pathways including overhead, conduits and capping, installers shall use materials and products that are the least obtrusive to view.
4.9 Single vendor solutions 4.9.1 New works 4.9.1.1 Systems All new cabling systems and work items within a specific building shall be a single-vendor system comprising both copper and fibre optic networking products and incorporating both the connectors, cables and mounting trays and panels. The Ministry of Education has reviewed and approved manufacturer’s products for use on its sites and facilities. All new works must utilise products from the approved vendor list provided and shall be installed by a Ministry Approved ICT Contractor, lists are located at; https://www.education.govt.nz/school/property-and-transport/suppliers/technical-information/responsibilities-of-an-ict-contractor/ Refer to Appendix B. 4.9.1.2 Warranty The cabling solution is to be supported with a single vendor’s warranty for a period of not less than 25 years. A “mix-and-match”, or “back-to-back” warranty structure using cabling and connector products and warranties from multiple vendors will not be accepted. The product exceptions to this are limited to (subject to these exceptions not conflicting with the manufacturer’s warranty): a) Cabinets and cable pathway products b) Cat 3/Voice-grade telecommunications cable only c) Patch cables and cable assemblies d) Fibre optic break out trays and unloaded patch-panels, consolidation points and
mounting hardware 4.9.2 Moves, adds and changes When moves, adds, and changes (MACs) are being undertaken on existing installations, and where a warranty is already in place for the existing installed system, MACs shall be consistent with the installed product and shall not, where possible, void an existing warranty. Where applicable the warranty for the existing system shall be extended to include the new works. 4.9.3 Existing infrastructure requiring maintenance If an existing Cat 6 link fails the Class E performance test as per AS/NZS 11801-1, and is not covered by current warranty it can be tested to Class D. If tested at Class D with a pass it can be retained, but marked on the as-built drawings, TO and horizontal distributor
45
records accordingly. If it fails Class D performance tests, re-terminate the cable and test again. If it still fails the cable shall be replaced.
4.10 Dimensioning The network requirements and configuration in any given area or classroom is to be determined and confirmed by the school. Sufficient TOs and accompanying GPOs shall be installed in all areas to meet the Ministry design guidelines as per the specific scope documents and tender documents.
4.11 Salt spray and corrosive environments Particular care shall be taken for installations in coastal regions to minimise the exposure of equipment to salt. Equipment enclosures and distributors shall not be installed in open areas. Equipment room vents shall be fitted with filters to minimise salt spray ingress. See NZS 3604 for additional information.
4.12 Chemical corrosion 4.12.1 Equipment rooms Equipment rooms and distributors shall not be located near to corrosive atmospheric or environmental conditions. Equipment and plant located in geothermal environments such as Rotorua, Wairakei or corrosive industrial environments, shall have appropriate corrosion protective treatments as follows: 4.12.1.1 Protection of electrical equipment Main distribution boards, control panels, server racks for the BMS and ICT, etc. shall be co-located in an environmentally controlled room:
(a) All electrical, telecommunications, IT and AV equipment rooms shall be
pressurised with at least 2 air changes per hour positive pressure by a
mechanical supply system with “CamPure 8” molecular filters. A controlled spill
air path shall be provided. The ICT designer shall coordinate with the
Mechanical Engineer for the implementation of this requirement.
(b) All equipment shall be protected against the effects of H2S (Hydrogen
Sulphide). This includes all bare copper, steel etc including electronics such as
protection devices/cards, etc
(c) All electronics shall be H2S resistant and shall be coated with an H2S resistant
epoxy coating. All electronic circuit boards, including PLC modules and PT
modules, shall have conformal coating in compliance with IEC 60721-3-3.
Conformal coating shall be to Class 3C2 as a minimum.
4.12.1.2 Support steelwork (a) The use of electroplated or galvanized components in a geothermal
environment is not recommended, as zinc will undergo accelerated corrosion
resulting in its early breakdown.
(b) Any zinc-based coating should be coated with a suitable industrial paint system
ending with an epoxy barrier coat, and where exposed to sunlight, a
polyurethane top coat to provide UV protection to the epoxy and achieve the
required colour aesthetics.
(c) Alternatively, a sealed thermal aluminium metal spray could provide the
optimum protection in this environment.
46
4.12.2 Storage areas Storage areas for cleaning solvents and other chemical products shall not be used to house cabling equipment and shall not be adjacent to equipment rooms or equipment room vents. 4.12.3 Wet areas Computer and networking equipment should not be installed in wet areas or rooms containing hot water cylinders, cleaner’s equipment, sinks or basins. If installation in a wet area is unavoidable, then approval must be received in writing from the Ministry and the school prior to commencement of installation.
4.13 Noise Equipment enclosure locations shall be selected such that noise levels in work areas arising from the enclosed equipment, when combined with other sources of work area noise, shall be maintained within the limits specified by AS/NZS 2107 Acoustics – Recommended design sound levels and reverberation times for building interiors. Recommended design sound levels for different areas of occupancy in buildings are given in Table 1 of AS/NZS 2107, from which the following design details are extracted and may also be reproduced with permission granted by Standards New Zealand under licence 001075.

Further information on acoustics can be found in NZS 6801, NZS 6802, AS ISO 140.4, and AS/NZS ISO 717.1.
4.14 Legacy systems The cabling system design shall consider the interface requirements of legacy equipment in existing installations. If any discrepancies are noted they should be highlighted in writing to the school or its representative. 4.14.1 Retention of legacy backbone cabling Existing Cat 6 UTP cables installed as backbone shall be replaced with OS2 fibre and OM3 fibre backbones shall be retained. See 6.2.5.2 for more information.
Installer note: If the backbone fibre is OM3 and is 300 metres or less, OM3 cabling can be retained if it would be more cost efficient.
47
4.14.2 Retention of legacy horizontal cabling A decision should be made by the on-site auditor and installer if existing cabling infrastructure could be retained, and then this decision shall be documented and supplied to the Ministry or its representative and the school. The following is a guide to assist in this decision: a) Only Cat 6 and Cat 5e cables should be retained b) For a good existing standard of installation then channel performance testing shall be
carried out along with all other channel performance testing required at the completion of the installation
c) There is no requirement for existing cabling to be warranted retrospectively but some may already have an existing warranty
d) Retained cabling should be integrated into the new installation as best as possible, labelled consistently but clearly identified as being excluded from the new warranty
e) Poor quality installations not meeting this Standard should be removed or modified to meet this Standard, where tests have failed then cabling should be removed
f) If no additional TOs and power outlets are required in an area (or block) then the existing cabling shall be tested to the appropriate link class and retained if testing is passed. The labelling of the existing TO's must be consistent with the rest of the site
g) The system designer will need to make an economic decision as to whether to replace the old system or retain it.
Existing ICT infrastructure cabling that is not properly secured e.g. laying on the ground that is being retained within the scope of a specific project shall be supported to adhere as closely as possible to Ministry requirements pertaining to the supporting of cabling. 4.14.3 Cable removal All cabling that does not meet the required Standard should be removed from site prior to any new installation where practical. Consideration should be given to service continuity and ensuring a minimal service disruption period during installation. This includes associated pathways and the repair of any building structures as a result of the removal. 4.14.4 Cable management systems Existing cable management in an enclosure can be retained and used for new cabling in conjunction with new installations providing this does not compromise the manufacturer’s warranty.
48
4.15 Fire rating All penetrations made by the Ministry Approved ICT Cabling Installer through fire rated walls shall maintain fire ratings where wiring goes through fire rated elements. This includes (but is not limited to): a) All penetrations, vertical and horizontal must be sealed utilising a system or product, or
both, that adheres to all requirements of the relevant specific building design, Standard, Ministry, Local Authority, and New Zealand Building Code regulations
b) All materials utilised for the sealing of the necessary fire rated risers and walls must be suitable for the purpose and comply with any Fire Safety Feature Reports that are issued and with all Local Authority regulations
c) Where fire rated walls are penetrated a suitable fire rated sleeve shall be utilised to reticulate the Telecommunications cabling through the opening and shall protrude to a maximum of 100mm either side of the penetration eg. Hilti sleeve
d) Vertical Risers and penetrations shall be sealed horizontally and utilise an easily removable solution that allows for future expansion and meets with necessary regulations
e) Photographic evidence shall be collected for each completed fire rated penetration. This shall include a time and date stamp, and form part of the completed handover documentation supplied to the Ministry of Education or its representative
f) If the installer identifies non-compliant firewall penetrations made by other trades or installers they shall notify the school or its representatives of the non-compliance immediately in writing.
g) Any penetrations uncovered by the ICT Contractor in existing firewalls that are not related to the work being carried out shall be notified in writing to the project manager, site owner and Ministry of Education via email to [email protected]. Repair work shall be outside the scope of the works being undertaken and shall be the responsibility school or their nominated project manager to organise and pay for the repair.
4.16 Electrical installation works ICT and networking installations may require electrical work to be carried out to complete the installation or programme of works. When electrical installation work is required as part of a network system upgrade the following shall apply: a) All electrical work shall be carried out by a registered electrician in accordance with the
Electricity Safety Regulations, applicable standards and the compliance document for New Zealand Building Code – Clause G8 Artificial light (for Equipment rooms and floor distribution locations) and Clause G9 Electricity
b) A special note should be taken of requirements for the installation of residual current devices (RCD) in New Zealand educational facilities, specifically the requirements laid out in AS/NZS 3000. Guidance on compliance options for schools is provided in the ELECTRICAL section of this document and in the Ministry of Education Electrical Installations: Standard for schools.
c) Electrical certification documents consisting of Certificates of Compliance (CoC) and/or Electrical Safety Certificates (ESC) and/or Records of Inspection (RoI) shall be issued for all relevant electrical work undertaken.
d) Electrical test results shall be recorded on CoCs or provided as supporting documents. e) Photographic evidence shall be collected for each completed fire rated
penetration, E2 penetration, cabinet fixing, main pathways and pit/duct installation. This shall include a time and date stamp, and form part of the completed handover documentation supplied to the Ministry of Education or its representative.
49
f) Should the contractor identify non-compliant electrical installations, they shall notify the school or its representatives of the non-compliance immediately in writing.
4.17 Electromagnetic compatibility There are presently no EMC regulations covering cabling installations and systems. However, the following cabling installation practices are recommended to limit the risk of interference to other services and the risk of interference from unwanted external emissions. For unscreened cabling, the EMC performance of the installed cabling is controlled by its ‘balance’. Balance is a measure of the control exercised over the physical relationship of individual conductors inside the cable or connecting hardware and is, therefore, a critical parameter during the manufacture of the high performance cables and connecting hardware used in generic cabling. It is necessary to utilise installation methods that maintain the original balance of the cabling components: a) Transmission equipment shall meet the requirements of AS/NZS CISPR 22 b) Complete systems shall meet the requirements of AS/NZS 61000.6.3. To facilitate satisfactory EMC performance of the overall GCS the design of cable routes and pathways shall take due consideration of requirements detailed in AS/NZS 11801-1 and AS/NZS 3084. In general, it is required that manufacturers of transmission equipment take full account of the contribution of the cabling to the overall EMC of the transmission system. In this case it is necessary to ensure that the performance of the installed cabling channel is within the limits specified by the transmission equipment.

4.18.4 ES3 cabling separation
The ES3 applications cabling shall not use generic cabling and shall be separated from other services as follow:
1. 150mm from ELV and LV (Including ES1 and ES2 applications)
2. 450mm from HV
3. 150mm from oxygen or flammable gas, heating and compressed air, water or waste
4. 150mm from ES1 and ES2
4.18.5 ES1, 2 and E3 required cable and outlet characteristic Cable resistance: The number of connectors between the SD and the SO will be minimised to ensure that the cable (24AWG or 0.5mm cable) resistance (0.0938 ohms per meter at 20 degrees Celsius) will not exceed the required cable resistance as specified by the cable manufacturer.

h) Any cable runs under buildings shall use catenary wires or trays. Where cables transition from underground ducts to catenary wires the duct exit point shall be plugged or sealed using some form of removable material. Rodent resistant polyester insulation wool may be used for this. Expanding foam is not permitted
i) Cables installed under decks shall be installed in a conduit to protect the cable from the environmental elements
54
j) Cables supported on catenary wires shall have a minimum ground clearance of 500mm where possible for serviceability and to reduce potential rodent damage. For all instances where 500mm clearance cannot be maintained from the natural ground level it shall be protected by a conduit, or external cable may be used
k) When vertical drops of cable exceed two (2) metres, catenary wire shall not be used as the means of support. The installer is to use tray or chain with appropriate fixings to prevent cable from slipping.
There is a need to address cable tray fill ratios to attend to cable bundle heat management on cable trays. Management of cabling on cable trays can ensure cable bundles do not overheat and avoid data loss in increasing the life cycle of cabling use. 5.1.3 Penetrations Fire rated elements and structural members shall not be penetrated without approval from the building architect, relevant Fire Authority, Structural engineer, and the New Zealand Building Code Compliance Clause C Protection from Fire shall be complied with. Where ladders or trays pass through ceilings, walls and floors provide neat, close fitting apertures. At openings through fire rated elements, terminate the ladders or trays both sides of the opening and provide holes for the cables only. All holes shall be fire-stopped with a proprietary product that exceeds the fire resistance of the materials being filled and is installed to the manufacturer’s specifications. Ducts that pass through walls, roofs, or floors shall be sealed to the manufacturer’s specification with an industry-standard duct sealing device to prevent the ingress of water. Where the cabling exits an external underground conduit and enters the structure, the penetration shall comply with the New Zealand Building Code Clause E2 External Moisture. Mechanical flashings shall be used to weather proof all external penetrations to the structure, with the use of sealant deemed a secondary means of weatherproofing. Any low level shroud used to protect a building penetration shall be constructed to ensure that the top surface is angled at approx 20 degrees. For low level building penetrations, the underground duct shall terminate in an appropriate weather proof enclosure of minimum L300mm x W200mm x D150mm. Cabling transitioning through the rear of the enclosure shall pass through a section of 50mm conduit inclined at a downwards angle of approx 10 degrees. All shrouds shall be manufactured from stainless or hot dip galvanised steel, and designed to meet the New Zealand Building Code Clause E2. Other materials may be used, with written approval for these from the school and the Ministry to be received prior to installation. Flashings shall aesthetically match the building as far as practicable (colour to be determined on site prior to ordering and installation). The installer shall ensure all installed flashings avoid health and safety issues, for example sharp edges, or pathway and access obstruction. 5.1.4 Metal pathways All metal pathways shall be bonded where required, as per AS/NZS 3000.
55
5.2 Inter-building pathways 5.2.1 General Inter-building pathways shall be constructed to accommodate the cabling between buildings. Inter-building pathways may consist of underground, overhead, and aerial pathways. 5.2.2 Cost Due to the cost and intrusion of creating inter-building pathways installers are advised to confirm the requirements of other trades and where possible co-exist in pathway or trenches to minimise cost. 5.2.3 Specifications Underground pathways are preferred wherever practicable however above ground routes may be necessary in some circumstances. As detailed in 5.4.1: a) The pathway shall be fully covered and the cabling shall be installed within a
protective, correctly specified UV stabilised conduit or ducting for the entire external section of the cable route.
b) Externally rated cabling shall be used in all inter-building pathways. 5.2.4 Crawl space Open and unsecured crawl space under elevated buildings must be considered as an external environment and proper consideration shall be given to the choice of components used in this space. Cable pathways in this area shall be protected as per 5.7.4. 5.2.5 External pathways All external pathways including junction boxes, ducting, trunking and conduits entering a building shall be protected against damage or vandalism for their entire length to a minimum height of 2.0m above the ground. Protection shall be in the form of a robust metal flashing of minimum 1mm thickness. The flashing shall be constructed of either stainless or hot dip galvanised steel. Other materials may be used, with written approval for these from the school and the Ministry to be received prior to installation. If the duct or conduit then continues up under the eve of the building, then it shall be protected all the way to ensure aesthetics are maintained and that it blends into the existing building structure. Where the new duct to be protected is directly adjacent existing plastic cable ducts following the same path, these ducts shall also be covered within the flashing. 5.2.6 Damage resistance All inter-building pathways maybe prone to vandalism and shall be protected against identified risks. 5.2.7 Manufacturer’s approval All ICT cabling pathway components shall be approved by the GCS manufacturer as suitable and approved within the warranty requirements of the vendor’s system.
56
5.3 Underground pathways 5.3.1 General design Underground pathways shall be designed and constructed in accordance with AS/NZS 3084. Where underground pathways enter into the interior of the building they shall be rodent proofed and sealed from the ingress of water to meet New Zealand Building Code Clause E2 External Moisture. 5.3.2 Trenches Trenches for communication cabling shall be constructed to provide a minimum depth of 450mm cover between the natural ground surface and the top surface of the communications conduit. Trenches shall be constructed such that installed conduits shall maintain a minimum longitudinal grade of 1 in 150 at all times. A longitudinal grade of 1 in 100 is preferred where practicable in accordance with AS/NZS 3084. Conduit may be installed by directional drilling providing the minimum cover to the natural ground surface can be maintained. A suitable warning marker tape shall be installed directly above conduit installed in a trench, at the appropriate level, for the entire length of the trench prior to backfilling to deter possible mechanical damage to data pathways by diggers. Backfilling shall be performed with due care to avoid distortion of the cable inspection pits and the conduit shall be supported firmly and evenly on all sides. Suitable fine grit material shall be used to surround pits and conduit prior to backfilling trenches. All trenches must be backfilled with fine grit up to the duct level and original excavated material removed from site or disposed of in accordance with the school’s requirements. 5.3.2.1 Fill ratios Fill ratios shall be approved by the designer, but shall not exceed 50% fill-rate on first installation, and 80% on subsequent MAC works, without the written authorisation of the Ministry or its representatives. Conduit For all conduits the following requirements shall be followed: a) A minimum diameter of 50mm for all newly installed conduits unless where otherwise
specified or approved in writing by the Ministry or its representatives b) Conduits and accessories should be UV stabilised and white, green or grey UPVC or

and/or to aid the ease of installation for any Telecommunications cabling d) If conduits are installed in exposed areas then they shall be installed on parallel paths
and change direction utilising appropriate bends and accessories required to form a right angle
e) Draw wires shall be installed in conduits that have spare capacity and also in conduits not currently in use. A minimum of 500mm of draw wire shall extrude from each conduit end and be fixed so as not to become unusable.
Underground conduits should be sized to accommodate backbone cables such that the conduit is not greater than 50% occupied at the time of installation. In addition:
57
f) The conduit shall extend into the pit for a distance of approximately 50mm through a close fitting hole.
g) All conduits and accessories shall be suitably manufactured and coloured for telecommunication cabling use
h) Sweeping bends shall be used to allow for cable bending radii i) The minimum size of conduit shall be 50mm and it is strongly recommended that a
spare 50mm diameter, PVC, communications conduit be installed along the complete route of the underground inter-building pathway system for future installations. A single 100mm conduit may be considered an acceptable, and perhaps better, alternative to two 50mm conduits
j) All conduit used on site shall be UV stabilised. All conduits shall be installed with a draw wire consisting of a 1mm conduit wire, a 3mm nylon cord, or a 12mm nylon ribbon
k) Conduits shall be sized to ensure the haul tension of the cable is not exceeded under installation.
5.3.2.2 Underground conduit building access Underground conduit shall either: a) Continue up and be fixed to the outside wall of the building to enter the ceiling space
through the eave, or b) Finish above ground level and the cable(s) fastened to a vertical perforated cable tray
fixed to the outside wall of the building. The cable tray shall be continuous from the conduit top to an access hole at ceiling space level. The access hole shall be sealed with a moisture and fire retardant material as per 5.1.3. The perforated tray, access hole, and cable(s) shall be protected by a steel top hat section. Both conduit and top hat sections shall be painted to match other building fixtures such as down pipes. Where underground cable enters a building, access shall be fit for purpose, comply with New Zealand Building Code Clause E2 External Moisture, and be protected from damage. 5.3.2.3 Flexible conduit Flexible conduit is not recommended, however if this is required to achieve a smooth directional change the following conditions shall be met: a) The flexible conduit must be UV stabilised and of PVC construction b) The flexible conduit must be painted grey or to match the colour of the solid conduit
sections c) The paint used must be UV resistant. d) Flexible conduit sections shall not exceed 0.5m in length.
58
5.3.3 Pits Pits shall be installed at suitable locations to facilitate installation and maintenance of cabling including: a) At distances not exceeding 50m along underground cable pathways b) Where a significant change of direction to the route occurs. The minimum pit dimensions shall be 450mm x 450mm x 600mm deep. All lids must be of solid construction and lockable. The locking mechanism shall be either a padlock or pit manufacturer method requiring a special tool to remove the lid. Any cable pit that requires access by Chorus shall have a minimum size of 600mm x 600mm x 600mm deep. Communications pits shall be of robust construction and suited to the conditions where they are installed. Pits shall have the following accessories: c) Secured and correctly rated (lockable) Pedestrian covers d) Secured and correctly rated (lockable) Trafficable covers where applicable e) Gaskets and seals (T-Dux or equivalent). Pits shall have non slip surfaces and should not be placed in or near designated play areas. Pits and pit covers shall be rated for their environment in accordance with AS 3996. Particular care must be taken when pits are in common walking areas or vehicle access roads. Where pits are installed in areas having traffic (this includes grass and field areas maintained by a grounds keeper using a tractor or similar), the correct approved strengthening ring for the pit lip shall be used. Pit lids shall have non-slip surfaces and be correctly rated for the expected exposure to heavy vehicles.
59
5.4 Overhead pathways 5.4.1 Overhead support systems Overhead pathways may be considered where buildings are linked by covered walkways or gantries. For all fixed conduit pathways, the conduit shall not be greater than 50% occupied at the time of installation. For all new buildings, overhead pathways shall not be permitted. 5.4.1.1 Use of existing service ducts Existing service ducts housed in walkways that run between classrooms, that are designed for the purpose of routing services around the school unobtrusively, shall be used where they are present and when there is enough spare space. Catenary wire may be used where service duct is enclosed. Externally rated cabling shall be used, and it shall be supported by catenaries installed in accordance with AS/NZS 3084. 5.4.1.2 No existing service ducts Backbone and horizontal cabling may be installed within conduit of 50mm minimum diameter provided that the pathway is fully covered. The cabling shall be installed within protective conduit or ducting for the entire external section of the cable route. Externally rated cabling shall be utilised. All external pathways including junction boxes, ducting, trunking and conduits entering a building shall be protected against damage or vandalism for their entire length to a minimum height of 2.0m. Installer note: If the duct or conduit then continues up under the eve of the building, then it shall be protected all the way to ensure aesthetics are maintained and that it blends into the existing building structure.
Conduits or ducts installed under covered walkways shall be positioned to prevent anyone from swinging on them. Installer note: When multiple ducts or conduits are installed under covered walkways or within a building, an accessible and aesthetically pleasing boxing shall be installed around them and painted to blend the pathway into the surroundings.
Stainless steel full saddles and stainless steel screws shall be used for direct fixing of conduit and pathways to an external structure where applicable. Full saddles and fixings shall be spaced at no more than 1m apart.
60
5.4.2 Aerial pathways In cases where underground or overhead pathways are not practicable, aerial pathways utilising catenary suspension systems may be employed. Aerial pathways shall meet the requirements of AS/NZS 3084, and the following: a) Aerial pathways shall be selected to avoid crossing power lines b) Where aerial pathways are indicated on the site plans, the GCS installer shall install
UV resistant, PVC-coated, flexible metal conduit between buildings. In this instance the length of conduit may be greater than 1m
c) The conduit shall be sized such that fill at the time of installation does not exceed 50% rated capacity
d) The catenary wires shall be terminated and sized to support the load of the conduit with 80% fill of cables under extreme weather conditions
e) Catenary wires shall be PVC coated galvanized steel and in no circumstances shall be less than 3.4mm diameter. Catenary wire shall be fixed to the buildings using eyelets and turnbuckles and bonded to the protective earth as required
f) The conduit shall be tied to the catenary with stainless steel cable ties.
5.5 Tunnels This Standard does not address the requirements for tunnels. In the event that tunnels are available or are required, the design and appropriate specifications shall be prepared by suitably qualified persons.
5.6 Intra-building pathways All pathways shall be installed with the expectation that they will be reused during the lifetime of the school. While it is accepted that the pathways inside the walls are more difficult to reuse, they can be made more accessible by ensuring cable is run vertically rather than horizontally. Intra-building pathways shall be constructed to accommodate the cabling within a building or blocks. In multi-storey installations, cabling between floors shall be routed via an approved communications cabling riser or duct. All ICT cabling pathway components shall be approved by the GCS/SCS manufacturer as suitable and approved within the warranty requirements of the vendor’s system. See 5.3.2.1 for fill ratios.
5.7 Horizontal cabling pathway components All ICT cabling pathway components shall be approved by the GCS/SCS manufacturer as suitable and approved within the warranty requirements of the vendor’s system. See 5.3.2.1 for fill ratios.
61
5.7.1 Horizontal cabling supports Horizontal ICT cabling shall be supported by an approved method – for example, cable tray, catenary wire – from the cabinet to within one (1) metre horizontally of the vertical channels used to deliver the ICT cables to their telecommunications outlets. In addition: a) No more than 24 cables of any type shall be tied to a catenary wire b) Cables shall be tied to catenary wires at 300mm intervals using a hook and loop tape
(minimum of 12mm wide tape) c) Cables installed on cable trays shall be loosely laid and secured not more than every
1.5m using hook and loop tape d) Catenary wire shall be supported at a minimum of every 3m i.e. support raw bolts
hooks inserted in above building level floor slab. 5.7.2 Cable trays Cable trays shall be perforated galvanised mild steel sheet or Aluminium construction. Minimum steel thickness for cable tray shall be: a) 1.0mm for trays up to 150mm wide; and b) 1.2mm for trays up to 300mm wide. Trays shall have folded edges with minimum height of 20mm. Where cable trays transition from a horizontal to vertical positioning, an appropriate solution to avoid cable crimping shall be installed at the point of transition. Where the cable tray is used as an earthing medium, electrical continuity shall be maintained along its full length. Cable tray support brackets shall not be more than 1.5m apart. 5.7.3 Cable trunking Trunking is used primarily to provide a pathway and expansion for TEOs and GPOs. Outlets are to be installed externally to the trunking flush to the wall (where access into the wall is available). If outlets are to be installed directly into trunking due to mounting on a concrete or block wall, the trunking is to be installed 750mm above the floor where possible to allow desks to fit under it. When new trunking is required to provide a pathway for new TEOs or GPOs, any existing services that utilise this pathway and existing pathways shall be removed, for example, mini trunking or conduit. Where twin compartment trunking is utilised for mounting data and power outlets, the top compartment shall be used for GPOs and these are not to be installed directly above a TEO. All metal and plastic trunking must support the required bend radius for Cat 6, CAT6A and any fibre cable installed to ensure all products maintain their warranty and comply with AS/NZS 4296. All trunking bends, tees and elbows that are installed onsite shall be pre-fabricated by the manufacturer or be a factory manufactured part.
62
Compliant plastic trunking must be paint absorbent, with a minimum UV stabilisation warranty of 10 years. Unless an alternative colour is stipulated by the school, the colour of the trunking will be white or similar. 5.7.3.1 Surface mounted trunking Surface mounted trunking shall be installed where alternative methods for concealment of cables are not possible. Twin compartment trunking shall be used to segregate power and data cabling. No exposed conduit or duct is to be used within buildings for feeding TEO’s or GPOs. Surface mounted trunking and ducting shall follow the natural vertical and horizontal lines of the room structure. It is preferable to install vertical trunking where possible in a corner if it is close to the outlet location or in a location to make it look as aesthetically pleasing as possible while maintaining expandability and flexibility. The fixing of surface mount trunking directly to the ceiling or other horizontal surface (lid facing down) should be avoided. Where this is necessary, VelcroTM ties shall be screwed within the trunking at maximum of 2 metre spacing to ensure that cables are retained when lids are removed. Alternatively, solid cross sections placed to hold the cable in place may be used. 5.7.3.2 Fixings Ducting shall be screw-fixed to walls using suitable fixings (for example cavity fasteners for cavity walls and masonry anchors for concrete walls) at approximately 1m intervals when run vertically and approximately 600mm intervals when run horizontally. Fixings shall not cause undue distortion to the ducting when tightened. 5.7.4 Under floor cabling Backbone and distribution cabling may be installed under floors when access permits. For all under floor cabling the following requirements are to be adhered to: a) Cables must be suitable for the environment in which they are installed b) Exposed standard distribution cables may be used when the under-floor space is dry
and not subject to spray or splashes. Cables should be installed clear of access and vent points
c) External grade cables (gel-filled or water-block) and rodent resistant cables should be considered when the cables are at risk. Alternatively, sealed conduits may be used to protect cables from damage by water or rodents
d) A minimum separation of 500mm shall be observed between fibre optic cabling and ground level. Where this cannot be achieved cabling shall be installed within plastic conduit of 50mm diameter
e) Where practical all internally rated copper cable shall maintain a minimum distance of 500mm from finished ground level, externally rated cabling may be used for cabling positioned between 200mm and 500mm from ground level
f) Any cabling installed within 200mm of ground level shall be provided with additional mechanical protection, that is, installed within 50mm plastic conduit maintaining the minimum bend radius and expansion requirements
g) In all cases the manufacturer shall be consulted to ensure the installation meets the specifications and requirements for warranty.
63
Installer note: It is preferred that cabling be concealed by installation in ceiling, floor or wall cavities. However, it may be necessary to surface mount cabling within ducting where no cavity exists or where concealment would prove to be inordinately expensive, disruptive or impracticable. Two-compartment duct shall be used to segregate power and data cabling. All ducting shall be run in an inconspicuous manner. Excess cabling shall not be stored in the ducting. Where cable is run in a false (suspended) ceiling it shall be suspended from fixed non-movable structural features, purpose installed flat cable trays, or from catenary wires. Fixed, non-movable features exclude water pipes, sprinkler systems and trunked electrical power. Cables shall not be laid on ceilings or ceiling tiles or attached to any suspended ceiling support structures. Plastic capping should not be used in new installations and low profile ducting should be considered where cable numbers are low. Capping may: a) Be used at 2m above finished floor height b) Be used for no more than two cables; and c) Be retained if 2m above finished floor height and no change is required. All capping shall be UV rated.
64
6. CABLING
6.1 General All cabling shall be installed in full accordance with the manufacturer’s recommendations. Cables shall be installed so that: a) Maximum permitted hauling tension is not exceeded b) Minimum bending radius of the cable is not exceeded c) Maximum permitted crush rating is not exceeded. Cable bundles shall not obstruct the installation and removal of equipment within equipment enclosures. Equipment and patch panels shall be laid out to minimise patch cord length. Patch cords shall follow clear paths to avoid patch field obstruction. 6.1.1 Balanced Cable Termination An RJ45 system shall be utilised at both the main communications centre and all remote cabinet locations. Cable termination onto a horizontal distribution panel or patch panel should be undertaken in a manner permitting additional cables to be terminated without unduly disturbing previously installed cables. Cabling termination to information outlets, patch cords, work area cords and patch panels is to be the T568A arrangement in accordance with AS/NZS 11801-1. The connecting hardware shall be installed to the manufacturer specification and to preserve wire twists as close as possible to the point of mechanical termination to minimise signal impairment. The amount of untwisting in a pair shall be as short as possible to permit the termination to the connecting hardware. To preserve the electrical characteristics of the balanced cable, the outer insulation of the cable shall not be stripped back more than recommended by the manufacturer for the purposes of termination. 6.1.2 Optical fibre cable termination The following fibre connector and adaptor colour codes shall be used for termination;
Multimode 50 m: Aqua
Single-mode PC: Blue
Single-mode APC: Green Multimode optical fibre cores shall be fusion spliced with LC terminated pig-tails. Single-mode optical fibre terminations shall be achieved by splicing LC pigtails to optical fibre cores using the manufacturer’s approved splicing techniques. Passive optical LAN (POL) solutions may use a combination of LC, SC and MPO connectors. Ministry of Education approval is required to implement a POL solution, if approved, the system designer shall be responsible for specifying the correct connectors required throughout their design. The cables shall terminate in fully enclosed, rodent proof 1-RU 12 port (24 fibre) or 24 port (48 fibre) LC duplex patch panels in the communications cabinets.
65
All fibre cores specified shall be terminated at each end and presented at the patch panel. The number of points at which through patching of multimode backbone fibre occurs shall be kept to one (1) maximum. The number of points at which through patching of Single mode backbone fibre occurs shall be kept to three (3) maximum. Should through patching be implemented in a design, the link attenuation shall still support a minimum of 10Gbps Ethernet once through patched end to end. Fusion spliced connection of inbound and outbound fibre cores at a communications cabinet shall not be permitted, except in cases where through patching must occur more than once due to geographical or distance constraints or repair or re-routing of an existing fibre is required due to building alterations. All fibre ports (adapters) shall have shutters fitted to prevent the entry of dust and other contaminants. 6.1.3 Passive Optical LAN (POL) Cabling and Design This standard does not cover POL cabling and design, however should a school, the ministry or designer wish to deploy a POL solution within a school this shall be permitted providing it is signed off by the Ministry of Education representative detailed under section 1.2.4. The POL cabling infrastructure shall be deployed and comply with this standard. This shall include, but is not limited to the use of Approved Manufacturers, Approved installers, Warranty, Testing and Documentation requirements.
66
6.1.4 Cabling type definitions The following definitions define the various cabling systems types as per AS/NZS 11801-1: a) Generic cabling systems: Structured telecommunications cabling system,
capable of supporting a wide range of standardised applications b) Service distribution cabling: Cabling connecting the service distributor to the
service outlets (SOs) of type A cabling or service concentration points (SCPs) of Type A and B cabling
i. Type A Generic cabling: Service distribution cabling between the service distributor and the service outlet
ii. Type B Generic cabling: Service distribution cabling between the service distributor and the SCP if a service outlet is not used
6.2 Backbone 6.2.1 Backbone cabling Backbone cabling includes both campus and building backbone cabling subsystems. The backbone cabling generally provides interconnection between active network equipment that may be within the same building or in separate buildings. All new campus and building backbone cabling shall be optical fibre. Any exception shall be approved in writing by the Ministry or its representative. See 6.2.5.2 for more information. Building backbone cabling runs within buildings and provides the interconnection between the floor distributors and building distributors, and in some cases between a campus distributor and building or floor distributors. Cabling requirements for voice communications depend on the technology used for voice switching. Internet Protocol (IP) Telephony systems transport voice signals as data over the common optical fibre backbone cabling. For the older (TDM) telephone systems dedicated balanced cabling will be required in the backbone. Installer note: Where backbone cables are run through ducting, sufficient slack of at least one loop must be retained in all inspection pits. All backbone cabling shall be labelled within pits using standard labelling conventions for the site.
6.2.2 Fibre optic backbone cables The increased bandwidth required by schools has resulted in optical fibre communication systems being implemented in a wide variety of environments to which both cabling practitioners and others might have access. The following specifications shall be followed:
67
a) All fibre optic network design shall be based on the performance and distance restrictions identified in AS/NZS 11801-1. The link-loss budget of the fibre link must meet the performance limitations of this Standard
b) All pig-tails shall be colour matched to the fibre cable c) All fibre optic connections shall comprise fusion spliced pig-tails. Mechanical
splices and field termination are not acceptable d) A minimum of OS2 fibre shall be used for all new fibre backbone cabling

i) All fibre cables will be presented in appropriate sealed fibre trays or distributors with compression glands for protection from rodent damage
j) All fibre fusion spliced terminations shall be presented on an approved splice cassette, firmly fixed within the fibre tray
k) Fibre optic backbone cables shall be run from the main equipment room via backbone cabling subsystems. Cabling subsystems may include a Campus backbone cabling subsystem and/or Building backbone cabling subsystem to a floor distributor (AS 11801-2) or service distributor (AS 11801-6).These cables may traverse Distributors assuming that link loss budgets are adhered to
l) Fibre Optic Break Out Termination (FOBOT) patch panels shall be rack mountable, hinged or sliding, with eye safe front (including laser warning symbol) and shall have integrated patch cord management
m) All fibre optic backbone cables shall have a crossover as per AS/NZS 11801-1. The crossover shall be implemented at the down-stream end of the link (farthest end from the main equipment room)
n) Each optical fibre cable shall be installed with 5m spare length in the communications enclosure at the respective distributors. The spare cable shall be stored so that it does not interfere with the opening of cabinets, FOBOTS, or servicing of equipment within the cabinet
o) Optical fibre bending radius shall not be less than 10 times the cable diameter (not less than 30mm) or as specified by the cabling manufacturer whichever is greater under no load conditions and 20 times the cable diameter or as specified by the cabling manufacturer whichever is greater under load, that is, when being pulled through conduits and the like.
Refer to APPENDIX C – CABLING WORK PRACTICES for more information.
68
6.2.3 Cable running or termination operations The following precautions shall be taken in these operations: a) Care shall be taken not to breach the cable’s protective sheath. b) Cables shall not be forced through openings that are too narrow or have sharp
or rough edges. c) Cables shall not be bent more than the manufacturer’s recommended minimum
bend radius. d) All building entry and cable pathway entry points shall be suitably sealed against
water ingress in a manner aligned with the New Zealand Building Code Document E2, with drip loops provided on cables where necessary.
6.2.4 Use of gel-filled cables Termination of gel filled cables into telecommunications cabinets shall be directed by the recommendations and warranty requirements of the system manufacturer.
Installer note: As there are no regulations or legislation that covers the use of gel-filled cables in New Zealand, the Ministry will not be restricted by a set distance for the entry of gel filled cables (copper or fibre) inside a building.
6.2.5 Campus and building subsystems For the purposes of the application of single vendor system warranties, all aspects of the campus backbone shall be considered part of the GCS and shall be included within warranties. The OSP campus network should be from the same vendor or manufacturer as the building systems vendor. 6.2.5.1 Installation Cables shall be: a) Rated for the environment in which they are installed b) Certified by the manufacturer for the environment in which they are installed.
External cables should be gel-filled water-resistant cables c) Installed in a manner that does not expose them to the elements and that
protects them from risk of damage or vandalism. Refer to 0 for more information on conduit sizing, fill rates and installation.
6.2.5.2 Channel length Fibre optic cables shall be used in all instances for backbones. In instances where Cat 6 UTP has been installed as a backbone link, it shall be retained to support existing services and a new fibre backbone installed as per this standard. An exception to this is only applicable where detailed within sections of this document, and approved in writing by the Ministry as per section 1.2.4. 6.2.6 Fibre optic terminations Fibre optic cable shall be terminated with LC UPC type fibre connectors.
69
6.2.7 Fibre optic patch cords Fibre optic patch cords shall be provided as duplex LC to LC except where used to interface equipment using connectors to optical patch panels. Patch cords shall be matched to the AS/NZS 11801-1 optical fibre cable type of the cabling system in which they are used. Patch cords shall be provided in standard pre-manufactured lengths (e.g. 1m, 2m, etc) sufficient to interconnect the optical fibre termination unit and switch/router hardware while minimizing the need to manage excess cable. Patch cords shall employ the following colour scheme:
a) Orange for OM1 62.5/125m (expansion or upgrades only)
b) Aqua for OM3 or OM4 50/125m c) Yellow for OS1a or OS2 (single-mode) d) Yellow and orange or grey for mode conditioning patch cords (yellow for SMOF
element, orange or grey for MMOF element).
Mixing of optical fibre patch cords and cabling, for example 50/125m cabling with
62.5/125m patch cords and vice versa, shall be avoided. The following patch cord connector colour codes shall be used;
Multimode 50 m: Aqua
Single-mode PC: Blue
Single-mode APC: Green 6.2.8 Cabling within enclosures All cables shall terminate at the patch panels in the communications enclosures with an excess length of five (5) metres for optical fibre and not less than half (0.5) metres for other cables neatly placed out of sight prior to terminating. Excess cable shall not be stored in “coils” but shall be formed into a “loop back” generally contained at one side of the cabinet up against a wall. Any excess length cabling must be properly supported. Cables terminating at the enclosures shall be neatly loomed within the enclosure, utilising the cable management system specified in 7.5. Cables shall be loomed between the space on the outside of the mounting rails and the removable door. Cables loomed inside wall mounted cabinets shall be loomed in groups of a maximum of 12, to allow enough space for mounting active network equipment.
70
6.2.9 Spare capacity A coil of cable (both fibre and copper) of at least 1m shall be left in each pit to allow for future expansion or maintenance purposes. All cables left coiled in the pits must be identified using water proof labels indicating the cabinets or points between which the backbone link is installed. At the distribution and work area ends of the horizontal cabling installation, provision should be allowed to house a certain amount of spare cable, for the requirement of re-termination or reconfiguration of the local cables. These spare cable capacity provisions are: a) Building distribution – half (0.5) metres b) Floor distribution – half (0.5) metres c) Work area (ceiling/floor) – one (1) metre d) Outlet (false wall) - three hundred (300) mm These spare cables should be stored in such a way as not to cause or induce any interference into the infrastructure, and so that it does not interfere with the opening of cabinets or servicing of equipment within the cabinet. 6.2.10 Copper (voice) building subsystem Gel filled copper backbone cables shall not be used in internal building risers. Internal grade Category 3 (Voice) can be terminated on either IDC modules or rack mounted patch panels as required. 6.2.11 Labelling convention The installer shall follow the labelling convention in use by the school. When this convention is inadequate or has conflicts, an alternative shall be provided. There is no requirement to re-label existing outlets. Refer to APPENDIX D – LABELLING CONVENTION for labelling convention and requirements.

75
7. EQUIPMENT SPACES
7.1 Equipment rooms The Ministry recognises the following styles of equipment and plant rooms within its network and makes specific minimum performance and design requirements of each style of room. a) Entrance facility (EF) b) Equipment Room (ER) c) Telecommunications Rooms (TR)
7.2 Equipment room design The designer shall: a) Be responsible to inform the architect and electrical engineer of these
requirements and to do this early in the schematic design phase of the project; and
b) Where these design requirements cannot be met, the designer shall advise Ministry and develop an alternative set of requirements for approval.
7.3 Entrance facility An entrance point to a building or facility for both fibre optic and copper cabling, and the space made for cable transition (from external to internal grade cable) is referred to as an Entrance Facility (EF). Most Ministry of Education schools do not utilise an EF. If they do, then the cable entry shall be constructed to ensure that water ingress and damage will not occur to Ministry property. In addition: a) The EF shall not be used as a patching environment, cable types transition from
external to internal in the EF by jointing or splicing b) External installers and facilities personnel are likely to need access to the EF
therefore an EF shall not be collocated within an ER or TR which are secure environments.
7.3.1 Sizing AS/NZS 3084 provides generic sizing information for commercial facilities. These sizing’s may not be suitable for schools, therefore supporting documentation supporting a decision to deviate from AS/NZS 3084 shall be provided by the designer to the Ministry for approval as per section 1.2.4. Typical layouts below shall provide guidance for architects/ ICT designers to ensure adequate space for ICT equipment inside the TR spaces and shall provide safe access to equipment In general: a) The TR shall be sized to match the functionality and size of the location b) The TR shall not be shared with electrical installations other than those
necessary for telecommunications.
76
The following schedule provides a summary of the required TR space sizes in relation to general guidelines for TR spaces sizing required serving following floor area sizes (m2):
Floor area size to be served by TR
TR space size required (Depth x Width) – TR space
entry is on the “Width” side of a TR space
TR space category
465m2 or less 3.2m x 2.4m Small Size TR space
466m2 to 743m2 3.2m x 2.74m Medium size TR space
744m2 x 929m2 3.2m x 3.4m Large Size TR space
The following schematics shows typical layouts and sizing of a TR based on the table above. These layouts shall provide allowance for the different services and features expected in a typical communication room:
Desiger/Installer Note: Distribution Boards required to service equipment located within the TR, as per AS/NZS3000 clause 2.10.2.2 shall have a minimum space of 1000mm or 600mm clear space from edge of switchboard board door when in its open position.
77
Equipment and telecommunications rooms The telecommunications rooms are building distributors (BD) and floor distributors (FD) whose primary purpose is house equipment and the distribution of GCS/SCS cables, and shall generally be considered as telecommunications rooms. The final size of the ER/TR shall be determined after developing the ER/TR design that accounts for all equipment footprints and incorporates all the defined clear working spaces. The following process shall be followed: a) No clear working space requirements shall be eliminated or reduced. ER/TR
layouts with inadequate clear working space for equipment are not acceptable b) Use the ER/TR “base size” from the above calculation including the required
clear working spaces for all systems designated for the TR c) If the ER/TR door swings inward rather than outward, do not use the wall space
behind the door swing for mounting panels, or equipment d) If additional space is required to achieve a compliant layout, adjust the length or
width of the ER/TR, and if necessary, expand the number of square metres accordingly
e) The TR shall have a minimum height from floor to ceiling of 2.4 metres without obstructions. A minimum headroom access of three hundred (300) mm shall be maintained above cable raceways.
The final size of the TR shall not be calculated until an acceptable equipment layout is developed based on the criteria listed above. All designs shall include an equipment room layout, detailing all services installed within the room and shall include dimensions. 7.3.2 Location Horizontal cable lengths have the potential to exceed ninety (90) metres between the patch panel and the terminal equipment outlet in the terminal equipment area, including the service slack requirements at both ends of the cable as identified in other sections of this document. 7.3.3 Security In general, it shall be necessary to pass at least two points of restriction to access equipment and server rooms. This can be generally achieved by using lockable doors to rooms housing equipment enclosures, and providing lockable equipment enclosures. Open racks in lockable equipment rooms accessible from staff-only areas may also be acceptable. Where schools already have burglar alarms installed, server rooms shall be secured by electronic security systems (access control, intrusion detection alarms). The TR shall have lockable doors as a minimum.
78
7.3.4 Lighting The TR average lighting level measured at one (1) metre AFFL between cabinets should be 500 lux in the horizontal plane and 200 lux in the vertical plane. Light fittings shall be mounted at least 2.4 metres AFFL, unless otherwise specified. Light fittings illuminating cabinets shall have a CRI of 90 or equivalent. Lighting installation shall comply with AS/NZS 3084 and AS/NZS 1680 Interior and workplace lighting requirements. 7.3.5 Power supply All cabinets shall have dedicated circuits installed and protected by a 30mA RCBO. 7.3.5.1 ICT specific wall mounted cabinet protection requirements Each wall mounted cabinet (less than 1.0kW input) shall have 1 x 10A dual GPO installed, supplied by a single dedicated RCD protected circuit. The dual GPO shall be mounted 150-200mm above the base of the cabinet. Surge protective devices (SPD) shall be installed at the switchboard to protect the entire phase supplying any dedicated communications cabinet circuits. A dedicated circuit breaker shall be installed to protect the SPD, and this circuit breaker shall not be used to protect any other sub circuits. All RCBOs protecting GPOs, the MCB protecting the SPD and the SPD itself shall be labelled at the switchboard, clearly referencing which cabinet they are protecting. 7.3.5.2 ICT specific free standing cabinet requirements Each cabinet (server & free standing greater than 1.0kW input) shall have 1 x 15A dual GPO & 1 x 10A dual GPO installed, with each having a separate dedicated circuit from the switchboard (on the same phase to mitigate 400v potential between GPOs). The power outlet shall be located on the wall placed low down inside the enclosure, approx 150-200mm from the bottom edge of the cabinet (single cabinet installation). For free standing enclosures, the power outlets shall be located on the wall either: a) 300mm above the floor behind the free standing enclosure; or b) 300mm above the floor inside the cabinet footprint. c) Mounted above the cabinet (side of cable tray). Individual 30mA RCBOs shall be installed for each dedicated circuit supplying cabinet GPOs. Surge protective devices (SPD) shall be installed at the switchboard to protect the entire phase supplying any dedicated communications cabinet circuits. A dedicated circuit breaker shall be installed to protect the SPD, and the SPD circuit breaker shall not be used to protect any other sub circuits.
79
All RCBOs protecting GPOs, the MCB protecting the SPD and the SPD itself shall be labelled at the switchboard, clearly referencing which cabinet they are protecting.
Electrical Design Note: A schedule is required to ensure designers and installers will allow for the correct RCBO required for specific UPS loads to ensure the electrical circuits are not posing a safety risk or a risk of equipment failure due to over current. The RCBO selection shall also allow for any potential in rush current from a UPS post a power outage and charging of flat batteries.
7.4 Air conditioning and temperature control Equipment in the ICT rooms and cupboards will generate heat. The heat created in this environment will, unless moderated, cause the air temperature to rise. Servers and associated equipment operate reliably only within certain temperature and humidity ranges and may fail if operated outside of these specified ranges. The vendor may decline to honour the warranty if it can be established that the equipment was operated outside its specified environmental range. Each equipment space shall be evaluated in regards to potential heat output and environmentally conditioned accordingly. Advice shall be sought from a suitably qualified person, but, as a guide, room temperature should be maintained between ten (10) and twenty eight (28) degrees Celsius. . A humidity of 55%-60% needs to be maintained in the TR space to avoid room temperature reaching dew point. Air conditioning units shall not be placed directly above a cabinet. See APPENDIX F – AIR CONDITIONING AND TEMPERATURE CONTROL for more information.
7.5 Enclosures and racks Communication enclosures are used to house and restrict access to cabling, active network components and other communications hardware. Enclosures may be free-standing or wall-mounted, and are designed for 19” equipment mounting. Cabinets mounted side-on close to a wall (to conceal and contain vertical cable entry from above or below) shall not be secured to that wall. Enclosures and racks shall not be placed next to windows or areas subject to direct sunlight (UV). In situations where this is unavoidable, the window shall be tinted, covered or blanked off. All newly installed cabinets shall be no more than 60% loaded at time of first installation and provide a minimum of 0.9m clearance front and rear for adequate access.
80
All cabling pathways into all cabinets must have rodent resistant polyester insulation installed to negate rodent access. 7.5.1 Cable management Racks shall be supplied with cable management panels to facilitate the support and organisation of patch cords between patch panels. For each 2RU of equipment in the rack there shall be a corresponding 1RU cable management panel which is deep enough to support 48 patch cords. Rear cable support systems are also required to offer strain relief for cables entering the rear of the rack and patch panels. 7.5.2 Balanced cabling patch panels Patch panels for balanced cabling shall be 24-way or 48-way modular socket (RJ45) with a port density of 24 ports per 1RU. The connecting hardware of the patch panels shall be rated to the AS/NZS 11801-1 Category 6A performance. New cable management shall be from the same manufacturer providing the performance warranty. 7.5.3 Optical fibre patch panels Optical fibre termination equipment shall provide cross-connect, interconnect or splicing capabilities. Optical fibre patch panels shall be combination type 1RU 12 or 24 port fitted with duplex LC couplers and cover plate. Patch panels shall be equipped with cable management facilities including splice trays. Patch panels shall be rack mountable, hinged or sliding, rodent proof, with eye safe front (including laser warning symbol) and shall have integrated patch cord management. All new fibres installed shall be terminated within this enclosure using manufacturer-approved fusion splice pigtails with LC connectors to maintain warranty. Terminated fibres shall be connected to LC connectors through shuttered adapters mounted on the faceplate of the optical fibre termination panels. Hardware shall minimise potential eye hazards from optical sources.
81
7.5.4 Seismic bracing All enclosures and racks shall be seismically braced to current New Zealand standards, refer to NZS 4219 for more information. Floor loading needs to be investigated to ensure cabinet integrity and safety. For the Ministry of Education current importance levels (IL) refer to the following link; https://www.education.govt.nz/school/property-and-transport/maintenance-repairs-security/earthquake-resilience/design-levels/ Free standing cabinets shall be seismically braced and securely fixed to the floor as per NZS 4219. Fixing requirements shall be determined by a structural engineer to the appropriate IL rating. Floors, including floor slabs for upper levels – If cabinet is braced to the upper slabs, and wall structures, must be able to sustain a minimum distributed floor loading capacity of 7.2 kPa as per AS/NZS ISO/IEC 14763.2 or 735kg/m2. 7.5.5 Free standing cabinets To avoid thermal cross-contamination between multiple free standing cabinets bayed together, the internal cabinet panels should be left fitted with bushed cable entry holes provided top and bottom to allow cable reticulation between cabinets. The cabinets shall have the following as minimum requirements: a) Thirty seven (37) to forty five (45) rack units (RU) high b) Minimum six hundred (600) mm wide, (800mm preferred) to provide space for

82
7.5.6 Wall mounted enclosures Wall mounted enclosures should be located to avoid injury and follow relevant Standards and OSH requirements. Top of the enclosure should be no higher than two thousand (2000) mm AFFL and the bottom of the enclosure a minimum of five hundred (500) mm AFFL. If this requirement is unable to be met, then written approval from the school and the Ministry for an alternative installation shall be obtained prior to installation. Designer and Installer note: The servicing of cabinets that are installed outside the AFFL measurements outlined above may have future financial implications to the school, due to more stringent OSH requirements for working
at heights.
Cabinets may only be mounted above a maximum vertical footprint of two metres when: a) This is required to mitigate a potential OSH hazard, for example the risk of staff
or students being injured on the cabinet bottom edge or corners. b) Physical constraints such as permanently fixed building elements or services at
otherwise suitable locations prevent the mounting of the cabinet beneath the two metre limit.
In cases where the top edge of the cabinet will exceed the upper maximum footprint of two metres, the following shall be carried out: c) A visible laminated sign of no less than A4 size, is be fitted to the front bottom of
the cabinet door. The sign shall state that access to the cabinet must be achieved using an appropriate sized ladder. For transparent cabinet doors, fix the label to the inside of the door to prevent removal.
d) Where possible, plastic or rubber corner protectors must be fitted to minimise the risk of head injury.
e) The cabinet must be documented within the school’s OSH register indicating the cabinet identification, cabinet location and that an appropriately sized ladder must be used by suitable qualified personnel to access and service the cabinet.
f) Striped hazard tape may also be considered for the bottom edge of the cabinet where this can be applied in a permanent neat manner.
In addition the wall mounted enclosures shall: g) Be twelve (12) RU minimum and twenty four (24) RU high maximum. When
more space is required a floor mounted cabinet is preferred h) Include a swing frame which shall be a minimum of one hundred (100) mm deep
and rear mounted to the cabinet i) Measure six hundred (600) mm wide by six hundred (600) mm deep, including

Open frame racks shall be: a) Mechanically secure and supported at the base and top b) Provided as 38RU or 45RU. Open frame racks shall be fitted with: c) Horizontal and vertical cable tidy panels or loops, or both d) A vertical cable tray e) A power rail providing not less than five (5) outlets. Open frame racks shall not be used to support heavy equipment – free-standing (4-post) enclosures shall be used for such equipment. Open frame racks shall only be used in communications rooms where access is restricted by a locked door. 7.5.8 Enclosure maximum equipment load Equipment enclosures shall be constructed to support the maximum equipment loads as follows: a) 12RU Cabinet Wall Mount – 30kg b) 18RU Cabinet Wall Mount – 45kg c) 24RU Cabinet Wall Mount – 46kg. Consideration shall be given to load bearing capacity of the floor when selecting or specifying floor mounted enclosures. See 0. Installer note: Enclosure installation Communication enclosures shall be located to achieve maximum operator convenience. The space available for a communications cabinet is to be verified on site. The installer shall ensure that racks are arranged to permit installation of other equipment and enclosures with adequate access spaces for inspection, wire termination and patch field alterations. Enclosures shall be: a) Provided with sufficient clearance for installation and maintenance activity b) Installed plumb and square without twists in the frames or variations in level between adjacent
racks c) Be bonded to the protective earth system The vertical footprint for wall mount enclosures shall not extend above 2m or below 0.5m from the floor. Wall mount locations shall be selected to avoid risk of injury by walking past or rising from beneath the enclosure.
84
Enclosures shall not be mounted on wheels or be moveable to allow for access. Equipment mounting rails at the front of the enclosure shall be set back so that doors may be closed without contacting equipment or connectors or distorting cable bends to ensure the minimum cable bend radius is maintained. Enclosure cable entry Cabling entering from the floor or ceiling space to enclosures shall be supported and concealed by a vertical cable support system. The vertical cable support system shall extend from the backbone/horizontal cable pathway to the enclosure. In the case of raised floors the vertical cable support system shall extend below the raised floor level. In the case of above ceiling pathways the vertical cable system shall extend above the ceiling level. The vertical cable system shall have a metal construction, colour and finish similar to the enclosure or interior building door.

If there are none, in office and administration areas they shall be mounted at 100mm above the desk or 500mm AFFL and, unless otherwise specified, mounted vertically or horizontally. Ceiling mounted outlets shall be mounted perpendicular to the building axis. The installer is responsible for informing the Ministry or its representative in writing (prior to completing any work) of any TEO’s scheduled for installation which do not have at least one GPO installed near or scheduled for mounting adjacent to or within one (1) metre of the new outlet. 8.1.1 Positioning terminal equipment outlets Where workbenches are fixed to the wall, outlets shall be installed above bench height. Where workbenches are positioned along a wall or benches have data distributed internally, a minimum of 800mm separation shall be maintained between the data outlets. Terminal equipment outlets shall be flush mounted wherever practicable. Mounting boxes, similar in style and colour to the flush plate, shall be used where flush mounting of communications outlets is not practicable. Outlets shall be located to avoid being obscured and terminal equipment cords being damaged by furniture and office equipment, and feet. The GPOs shall not be mounted in such a way that extension cords, multi boxes or power leads are required to cross access ways. TEOs and GPOs shall be mounted as close as possible to the areas requiring service. All cable pairs at the terminal equipment (TEO) or service outlets (SO) and at the distribution panels shall be terminated. Designer and Installer note: The designer shall design all cabling and service outlet (SO) locations required to support wireless throughout the entire installation as detailed in the Ministry wireless standards. Designers shall include in their design cabling to support AV devices installed in all spaces throughout the school. AV devices are defined as but not limited to; Projectors, TVs, Mobile TVs, Streaming media devices (Appletv, Chrome cast etc.), Video Conferencing, Display TVs, Video Walls and wayfinding etc. The designer shall determine the requirements and placement in consultation with the school.
86
8.2 Floor boxes It is recommended that floor boxes should not be installed in schools. If floor boxes are to be installed, they shall be constructed from durable material capable of withstanding a 150kg load and have approximate dimensions: 245 mm square (or round) with a minimum depth sufficient to fit a standard TEO or GPO wall plate and to maintain the bend radius and performance requirements for a Cat 6A
cabling installation. The mounting of the floor box shall be such that it is flush with the floor and does not present a hazard to any user. A floor box with a carpet insert shall be used to allow the floor box to blend into the surroundings. Each floor box shall be able to accommodate a minimum of four GPOs and maximum of four TEOs. To prevent debris or foreign objects from damaging the outlets or presenting a hazard to the user, the mounting of GPOs and TOs shall be such that they are not facing directly upwards. Power and communication cables shall be provisioned such that separation is maintained. The floor box shall have sufficient capacity for four power cords and four work area patch cords and maintain separation with sufficient protection to prevent damage to cables. The floor box entry holes through which horizontal data and power cabling is passed shall be bushed to prevent cables being damaged on metal edges. Each new floor box shall be fed with a minimum of two 40 mm conduits when installed in a concrete slab. In order to ensure that circuits can be repaired, replaced and upgraded in future: a) There shall be no hard 90 degree corners used and all changes in direction will
be made using sweeping bends b) No conduit shall be more than 50 % full at completion of project. Earthing of floor boxes shall be carried out in accordance with the requirements of AS/NZS 3000.
8.3 Flush mounted faceplates All TEO's shall be flush mounted, where possible utilising the wall cavity. The TEO shall be located so that, after removing the faceplate, a user can disconnect and replace the terminal equipment area cable assembly. The TEO mounting support shall be suitably fire rated and protected if required, the slack or spare cable should be located at the next convenient access point. The terminal equipment area cable shall be installed in a suitable location, to ensure it can be easily replaced.
8.4 Radiators TEOs and trunking shall not be installed within 100mm of radiators in any direction.
87
9. EARTHING AND TRANSIENT PROTECTION
9.1 Earthing A Telecommunications Reference Conductor (TRC) system performs a functional role only and shall not be used for protective earthing purposes. A TRC system is not generally required unless otherwise specified by design. All equipment racks and cabinets, cable trays, and metal duct systems shall be earthed in accordance with AS/NZS 3000 to the building protective earth system. Earth wires shall be used for the general earthing of metal structures (communications racks, catenary, cable tray, frames, and so on). Connection to catenaries shall be by way of a brass or copper line tap. Connections to cable tray or metal structures shall be via a suitably sized terminal lug, and serrated star washer, ensuring that any paint is scraped back to bare metal. The Ministry of Education has a preference for a single earth wire connect into each earth bar connection point for ease of long-term maintenance, however should a free standing cabinet be filled with shielded patch panel’s this may not be practical, so the contractor shall install no more than 3 earth wires into any one (1) earth bar connection point. Solder shall not be used as the primary connection method for earth connections. Each rack shall be directly earthed to the local earth bar. (It shall be possible to remove a rack without interruption to any other rack earth)
9.2 Transient protection Where available, applicable, and cost effective, transient protection equipment should be provided for protection of equipment connected to balanced copper outdoor cables where such equipment can be provided without compromising transmission performance.

11. WIRELESS ACCESS POINTS
11.1 Wireless LAN Design The design and installation of a wireless LAN system within a school shall comply with the latest version of the Ministry of Education Information and Communications Technology (ICT) Wireless LAN Infrastructure: Standards for Schools Because of the diversity of school sizes, building layouts, and wireless connectivity requirements, recommended wireless system configuration parameters are described within the wireless standard. Schools are encouraged to discuss their requirements with an independent designer or ICT consultant prior to purchasing hardware. The installation and configuration of any wireless system shall be completed by a suitably qualified person. It shall be the responsibility of the ICT Consultant to design the cabling infrastructure required to provide the coverage and performance necessary to meet the Ministry of Education wireless standard for any new or refurbished school building.
11.2 Wireless LAN (WLAN) location While the wireless system is not considered to be a part of the Schools cabling infrastructure, the provisioning of the cable to support the wireless access points is and shall be designed into a new cabling installation as per the Ministry wireless standard. Industry best practice, is to use a specialist ICT Consultant to design the WAP placement and use predictive mapping tools to assist with placement and building structure obstacles.
The GCS installer shall be responsible for the installation of the cabling required to support the Access Points. For an existing installation, it is recommended a site survey be undertaken by a suitably qualified independent wireless designer to determine the optimum mounting locations for the wireless access points. All wireless systems shall be selected and installed to Ministry of Education wireless standards requirements.
91
11.3 Wireless access points – installation and cabling The installation of wireless access points shall comply with the Ministry of Educations wireless standard. For all new cabling installations, there shall be a minimum of a dual Cat 6A shielded service outlet installed for every wireless access point. Permitted Exemptions;
1. The first exception to this shall be for relocatable or temporary classrooms fed
from an existing adjacent buildings cabinet, under this situation the installation
of a single externally rated Cat 6A gel filled shielded cable and Cat 6A Jack
shall be permissible to each wireless access point location.
2. The second exemption is for POL installations where the WAP is directly
connected to an ONT via a patch-cable, these may also be a single Cat 6
patch cord.
The SO’s that connect to the Wireless Access Points (WAP’s) shall be fixed to structural members of the building where possible, alternatively the use of manufacturer approved mounting fixtures can be used subject to Ministry approval (as per section 1.2.4). The SO’s shall be permanently and clearly identified and labelled. They shall be installed in a readily accessible location. Final placement of the WAP shall be achieved by the use of patch-cables. Patch-cables shall not be longer than 5m when connected to a SO. If the consultant has specified the use of MPTL connections, the patch-cable length may exceed 5m, but shall comply with the requirements under the MPTL section of this document. When a WAP is fitted on a ceiling tile, the SO’s may be installed above the ceiling tile as long as it can be readily accessed to allow the patch cables to be fitted. The ceiling grid shall be labelled with the SO numbers to indicate there are SO’s in the ceiling space above and make finding the SO and fault finding easier. The installer shall refer to the “Power over ICT Cabling Infrastructure” section of this document for additional labelling and testing requirements for remote powering. Any WAP fitted on a ceiling tile shall have an additional seismic safety chain (or nylon coated multi stranded steel wire harness rated at 50kg minimum) fitted and attached independently to the ceiling grid or beam above the ceiling tile.

APPENDIX A – HERITAGE SITES (Informative)
A1. General Many older sites have objects such as buildings or trees that may have a heritage status, or be deemed as protected by a local or regional council. Information is often not easy to find and can be located in different places depending on the local or regional council. In addition to the heritage status and council designation the site may also be recognised as an archaeological site or one of significant Maori heritage. Often schools and SPAs are not aware themselves of heritage status of some of their buildings. If a building is suspected of heritage status the following information can be used to determine the any details
A2. Historical Sites Historic sites are registered in the New Zealand Historic Places Trust (NZHPT). The NZHPT has a regulatory role regarding protected historic places, archaeological sites and sites of importance to Maori and may prosecute under the Historic Places Act 1993 There is likely to be historic significance if the school was built pre-1930s. The auditor will need to search the Historic Trust’s register located at http://www.historic.org.nz/theregister. It’s useful to search the suburb or town to ensure that all historic places in the area are captured. Care needs to be taken when dealing with suspected historic places. Confirmation from the school or SPA is not sufficient and if heritage significance is suspected, confirmation in writing from the NZHPT must be received.
A3. Archaeological Sites An archaeological site is defined in the Historic Places Act 1993 as any place associated with pre-1900 human activity. Any works that may affect an archaeological site must have written authority from the NZHPT before work begins. Archaeological sites may be listed in the NZHPT register or, in a council district plan, or council database. If in doubt, contact the NZHPT at [email protected] AND the relevant council. References to archaeological sites can be found at: http://www.historic.org.nz/protectingourheritage/archaeology/digitallibrary.aspx
96
Within this page there is a catalogue (in Excel format) of reports that have been completed. There are many schools listed in this index including some new schools recently built. The relevant report can then be requested at no cost2.
A4. Maori Heritage Māori heritage can be divided into the physical/tangible, natural and intangible. The NZHPT employs specialist Pouārahi (Māori Heritage Advisors) and other staff based in its offices in Kerikeri, Auckland, Tauranga, Christchurch and Wellington. If the site (or locations within the site) is suspected as of Maori Heritage then contact the NZHPT for advice on proceeding further. This may be necessary around a Marae (particularly if it is a very old site), or if old carvings are present, and so on.
A5. Council Designation The NZHPT does not manage all historic places and many of them are managed by the local or regional council. Councils have responsibilities under various pieces of legislation for heritage management and protection, notably the Resource Management Act, Historic Places Act, Building Act and Local Government Act. Sites may be protected under a council designation and each council and region has a difference database and method of accessing that database. Some councils only have these listed in their district plan and other councils may not have digital records or a searchable database.
2 This is only the list of reports; it is not necessarily the complete list of archaeological sites.
97
APPENDIX B – APPROVED ICT CONTRATORS LIST (Normative)
B1. Approved ICT contractors list The Ministry, schools, and their agents (such as project managers or designers) shall select suppliers from the Ministry’s Approved ICT Contractors List for the following categories of ICT services and products: a) Structured cabling installation services b) Structured cabling product supply c) Wireless integration services. This requirement is to be followed whether the ICT work is undertaken by any Ministry programme of work, or independently by a school. Over time, the list is intended to be extended to include other types of ICT contractor. The list of approved ICT contractors can be found at; https://www.education.govt.nz/school/property-and-transport/suppliers/technical-information/responsibilities-of-an-ict-contractor/
98
APPENDIX C – CABLING WORK PRACTICES (Normative)
C1. General safe work practices and responsibilities The installer shall ensure that all persons working on any Ministry school or facility that is under their control are protected from risk created by residual materials and workmanship associated with any construction works, including ensuring all areas are cleaned after fibre optic work to ensure no sharps or splinters of fibre remain, and the removal of all sharp and hazardous edges from fittings.
C2. Work areas Work areas for terminating copper and fibre optic cables, and splicing optical fibre cables shall: a) Have adequate lighting and ventilation b) Be kept free of debris and other contaminants c) Ensure optical fibre off-cuts are removed from site and disposed of in an
appropriate manner d) Ensure sharps and syringes used as part of optical fibre cabling are disposed of
in an appropriate sharps container and removed from site e) Ensure a medical waste or clinical waste container will meet the requirements of a
sharps container.
In addition: f) Sharps containers shall be disposed of by direct burial or incineration g) Sharps containers shall not be disposed of via domestic and standard industrial
collection services h) Sharps containers shall be disposed of off-site separately from other site waste i) Chemical waste shall be removed from site and disposed of in an appropriate
manner j) Washing of hands both before entering and after leaving the work area shall be
required for all persons working on the site k) Food or beverages shall not be consumed or brought into the work area.
C3. Fibre Optic - General Health and Safety The handling, installation, testing and operation of OFCS involve inherent risks that require safety precautions to be taken. Silicate optical fibre is very thin and is usually made of pure glass. The process of scoring or cleaving this type of material results in small glass shards that is difficult to see and avoid if left lying around the work area. Accidentally brushing a hand across a workbench can cause tiny shards to penetrate the skin and potentially migrate further into the body. These sharp particles can cause direct damage to the body and can also cause infections to set in.
99
If the glass enters the eye, damage to eyesight, including blindness, can occur. Unlike wood slivers, these glass splinters will not degrade inside your skin. The signals transmitted over optical fibre commonly comprise high intensity infra-red light that is not visible to the human eye and can cause permanent tissue and eye damage when exposed to the human body. For all medical emergencies related to optical fibre installation and operation, immediate medical attention shall be sought. As a minimum the following emergency equipment shall be available on site or within a mobile work space when work involving fibre optic cable termination or splicing is being undertaken: a) Eye wash b) Tweezers c) Magnifying device d) First aid kit.
C4. Fusion splicing All fibre optic cables shall be fusion spliced. Fusion splicing is an effective method of joining optical fibres. However, it entails the melting of glass by electric arcing, which occurs at temperatures exceeding 1700ºC. The following precautions shall be observed: a) The use of fusion splicing in hazardous areas as defined in AS/NZS 2430.3.1
shall not be permitted without ensuring full compliance to all relevant standards and OSH requirements on site. Hazardous areas as defined in AS/NZS 2430.3.1 are all areas containing flammable gases or flammable liquids that may give off vapours and areas prone to potentially explosive dust clouds
b) Gloves, or barrier cream, or both, shall be used c) Material safety data sheets (MSDS) shall be provided for all optical fibre materials
involved and cable manufacturers’ warning and recommendations shall be observed.

All horizontal subsystem cable ends at the rear of patch panels and behind TEOs or SOs shall be labelled with permanent marker. All fibre optic and copper backbone links shall be labelled on the cable using a permanent marker; the label shall clearly indicate the two cabinets or points between which the backbone link is installed. The label shall be applied as close as possible to the fibre tray or panel on which it terminates. The method of designation shall be in accordance with AS/NZS 3085.1 and as described below. For example, a backbone link between cabinet AG1 and BG1 when standing at cabinet AG1 shall be labelled: AG1-BG1. The same link when standing at cabinet BG1 shall be labelled: BG1-AG1. All retained cabling shall be labelled in a consistent manner to the new installation.

applied to indicate the two cabinets or points between which the backbone link is installed. For fibre trays the label shall be placed on the front face of the tray.
For example a 6 core fibre backbone link between cabinet AG1 and BG1 when standing at cabinet AG1 shall be labelled: AG1-BG1 BF01-06. The same link when standing at cabinet BG1 shall be labelled: BG1-AG1 BF01-06. Backbone IDC blocks (where used) shall be designated according to the particular installed configuration. Generally the blocks will be arranged in a number of verticals with pair numbering commencing at the top left of the respective vertical. Ports shall be designated as Xmno where X indicates the vertical and mno indicates the pair number.
D4. Horizontal cabling The horizontal wiring shall be labelled with the enclosure and patch panel port identifiers as specified above. For example A12-073 could signify horizontal port 73 from enclosure 2 on level 1 of the Administration building Labels shall be attached to the cable at both the rear of the telecommunications outlet and the rear of the patch panel by using the computer generated cable label. The size and length of the marking system carriers shall be sized to suit the cable size and the text required for proper identification.
D5. Labelling of outlets Each telecommunications outlet shall be labelled with the unique enclosure and patch panel port identifier. For example, the outlet designated A12-073 would be connected to patch socket 073 in cabinet A12. The label shall be clearly visible and securely mounted with the identical label provided on the back plate using permanent marker pen.
102

Designer note:
It is important that the designer meet with the schools committee or authorised point of contact for ICT needs and create a functional brief. The functional brief should then be translated into the ICT Design requirements. The number and location of outlets to facilitate connectivity to the services outlined in the functional brief will vary from school to school and therefore in order to design a fit for purpose space the quantity and location of outlets cannot be stipulated, unless the design is a repeat of a Ministry referenced design e.g. Avalon, Canterbury or Nelson Block modernisation as detailed on the Ministry of Education website. At the completion of the design the designer shall obtain sign-off from the school that the design meets the Design Brief and is fit for purpose.
APPENDIX F – AIR CONDITIONING AND TEMPERATURE CONTROL (Informative) Computer and networking equipment is designed to operate within a fairly narrow temperature range. To ensure reliable operation and the longest possible life from components the temperature must be kept within the range specified by the manufacturer. For new schools and schools undergoing extensive renovation the consulting engineers engaged on the project will be able to advise on the need for air conditioning to control the temperature in server rooms. For existing schools building a computer network and establishing an ICT main equipment room for the first time, and schools expanding an existing computer network, professional advice on the need for air conditioning might not be so readily available. The following may provide some guidance. Servers and other electrical and electronic equipment in the ICT equipment room generate heat. The heat created in the room, unless extracted, causes the air temperature to rise. Servers and associated equipment operate reliably only within certain temperature and humidity ranges and may fail if operated outside these specified ranges. Furthermore, the vendor may decline to honour the warranty if it can be established that the equipment was operated outside its specified environmental range. General recommendations suggest that the temperature should not go below 10°C or above 28°C. In larger equipment rooms (more than 2 free standing cabinets) the air temperature must be controlled by air conditioning and professional advice shall be sought. Although this seems a wide range these are the extremes and it is far more common to aim at maintaining the room temperature around 20-21°C. To do this reliably, dual redundant air conditioning units are essential. For a small school the operating and maintenance costs for an air conditioning unit may prove difficult to sustain and it may be possible to control the temperature of small server rooms by a simple, thermostatically controlled extractor fan. Servers, network switches, firewall appliances and routers are typically specified to work in temperatures up to about 35ºC but a margin for local hot spots must be allowed and 28ºC is a maximum safe air temperature at the extractor fan. Cold temperatures are unlikely to cause problems in New Zealand if a thermostatic fan switch is used. In principle it is easy to calculate the amount of cooling necessary for a server room by simply adding up the heat input and installing an appliance that can remove that much heat. In practice it is rather more complicated.
Assuming good insulation, limited windows and doors, or an internal building space, solar heat input to the server room may be ignored. Small ICT equipment rooms will typically include the following heat generating equipment:
Equipment Heat in Watts
Server 400
Ethernet switch x 2 100
UPS 100
Lighting (only when door is open)
Total heat input 600
Given the specific heat capacity of air (1.2kJ/m3.ºK) it can be shown that for each kW of heat to be extracted, 50m3 of air must be pumped through the room per minute per 1ºC temperature rise between inlet and exhaust air. For example, to remove 600W of energy, using air at an ambient temperature of 20ºC and permitting the room temperature to rise to 28ºC maximum, would require a fan to pump 3.75m3 (say 4m3) of air per minute. This is equivalent to a complete air change in a 2mx2mx2.4m server room every 2.5 minutes.
Volume of air CWm 05.03
where W is heat in Watts and ºC is air temperature rise. This simple calculation ignores impedance to air flow and assumes minimal pressure drop between air inlet and extractor fan. A 250mm wall fan venting directly to outside can pump between 8-12m3 per minute providing there is unrestricted airflow into the room. The problem with forced ventilation becomes immediately obvious when higher ambient temperatures are encountered. At 26ºC ambient air temperature, not uncommon in some regions, the amount of air to be pumped increases to 15m3 per minute. The typical layout for a small server room might place an air inlet grill, of at least 1.5 times the fan area, low down on the door and the extractor fan high on opposite wall. In summary, the choice of extractor fan is important and if high ambient temperatures are common in summer or room heat loads are likely to exceed 1kW, professional advice on air conditioning should be sought.
