Excel Installation Guide

IntroductionThis installation guide has been produced to assist the Excel Partners with the best installation

practices or the Excel Structured Cabling System. The Excel Structured Cabling system meets the

component perormance and conguration requirements o EN50173 or the Class o perormance

desired. The location is based on a Class 1 environment in terms o M, I, C, E. The design o the

cabling system and containment solution into which it is to be installed should be compliant with the

requirements o the EN50174 and EN50310 standards.

PlanningBeore you start, prepare to start.

l Have you got the cabling system design mapped onto the layout o the space?

l Do you have the correct materials ordered against the Bill O Materials estimated to complete the project?

l Has the re stop solution been approved?

l Do you need any specialist training or product support rom Excel?

l Are the deliveries scheduled to match the installation plan?

l Are there any site inductions required? I so, when are these held?

l Is the area to be handed over to you or your installation? I so, in what condition? Will you be required to run a Permit to

Work scheme or you and other trades?

l Is there a clean, dry, secure storage area allocated or your materials?

l Are there any special precautions to observe or site Health and Saety?

l Are the method statements and COSH statements or the installation, termination and testing approved?

l Do you have a change control process and reporting scheme?

l Do you need to notiy the site with the names or identication or your sta?

l Is the labelling method, scheme, style, colour agreed and approved by the client?

l Is the test equipment serviceable and to specication?

l Is there a headroom perormance requirement rom the tested cabling?

l Have you agreed how to deal with a star pass, (ie. marginal results)

l Do you have access to power outlets or testers, laptops etc?

On sitel Is the containment installed in the correct place and to the right specication?

l Are you holding daily briengs or the site operatives?

l Is there any temporary re stopping required during the installation phase?

l Is there any dierence between the reality o the site and the plans?

l Are there any access restrictions or other trades working in the same areas at the same time?

l Is the earthing and electrical system installed?

l Is there restriction on the use o mobile phones or walkie-talkies?

without compromise.

Site Environment ClassicationThe environments where cabling is to be installed are classied to cover the dierent conditions under which the cabling is required to

operate. Conditions which may aect the cabling perormance are used to determine the applicable environmental classication. Use

the environmental classication to select the components. The same classication is used to determine the appropriate containment

and installation techniques.

The local environment along the channel is classied or each M, I, C, or E group, and the classication o an environment is determined

by the most demanding parameter within the M, I, C or E group. With regard to temperature, the local environment is considered to be

the operating temperature o the cabling.

The considerations or:

l Mechanical rating include shock/bump, vibration, crush, impact, bending, exing and torsion

l Ingress rating include particulate ingress, immersion

l Climatic and Chemical rating include humidity, rate o change o temperature, solar radiation,

damaging chemical concentration

l Electromagnetic rating include electrostatic discharge, conducted radio requency, magnetic eld

All twisted pair copper cabling supplied by Excel or normal indoor use is designed and classied to perorm in a Class 1 environment(M

I you have a specication requirement which is beyond Class 1 use you must consult with Excel technical support or guidance on

containment and product selection.

Containment and Cable RoutingPower and Data Separation

Local and national saety regulations may require dierent separation or segregation distances. Separation and segregation or saety

must take precedence over all other requirements. To reduce the risk o noise disturbing the data owing in copper twisted pair cables,

Excel recommends ollowing the requirements set out in the latest issue o EN50174; these are summarised below. The more stringentrequirement (greater distance) shall take precedence.

Essentially there are two ways o mitigating the eects o noise disturbing the transmission o data in a copper twisted pair cable; one

way is to separate by distance the twisted pair cabling rom the noise source, using air to attenuate any noise; the other way is to provide

a barrier between the noise source and the twisted pair cabling using a grounded barrier to attenuate

the noise.

The actors to consider are:

l Environment

l Type o containment

l Perormance o cable type

lApplication being supported

l Construction o power cable

l Scale o power source

l Proximity to the power cable

without compromise.

When all o this is calculated you get a separation recommendation.

Environment: All twisted pair copper cabling supplied by Excel or normal indoor use is designed and classied to perorm in aClass 1 environment M

1, E

1.

Containment: No barrier or no metallic barrier (typically wall trunking or open ladder), open metallic (typically basket but notladder), perorated metallic (typically slotted tray) and solid metallic (typically 1.5mm wall steel conduit).

Cable Style: The perormance o the cable and connector set is provided by the manuacturer. The applications to be supportedwill be the determination actor that provides the Classication or the cabling system chosen.

Power Cable: An assumption is made that power cables will provide a high degree o sel cancellation or any noise carried ithey are constructed with a live, neutral and earth bound together in a common sheath. I individual tails

are used (separate unbound conductors) then power cable is to be treated as a noise hazard.

Power Scale: How many power cables are present or likely to be installed? Classication or power cabling is based on thequalication o a single phase 230 Volt, 20 Amp circuit. Three phase power is to be treated as three times a single

phase. For circuits which are more than 20A treat as multiples o 20A. Lower voltage AC or DC power cables must be

treated on their current rating, e.g. a 100A 50V DC cable is equivalent to 5 o 20A cables.

Overhead and Under Floor Containment Fill RatioCable trays, basket, ladder racking and other containment should be lled on day one:

l To accommodate a day one minimum calculated spare ll o 20%

l Up to a maximum o 150mm (6 in) cable depth or solid oor containment.

The spare capacity requirement is to allow room or uture expansion, and to acilitate additions and removal o cables once the building

becomes operational

NOTE: A calculated ll ratio o 50% will physically ll the entire containment due to spaces between cables, and random placement.

Picture shows a cable tray that is ull o cable which equals a 50% ll ratio

Example - What is the minimum width o a 75mm deep cable tray supporting 1000 cables, each with a

diameter o 5.5mm?

Area o one cable = (cable diameter)2 x

Area o one cable = (5.5)2 x 3.14 = 23.75mm2

Area o 1000 cable = (5.5)2 x 3.14) x 1000 = 23746mm2

Multiply this occupied area by 1.2 to give 20% over size or day two expansion

Usable area or Area required within cable tray (50% ll) = cable tray width x cable tray depth

1000 cables = (23746mm2) x 1.2 = cable tray width x 75mm

Minimum width o cable tray = 759.9mm

Heating EectsEnergy losses rom within cabling will be translated into generation o heat. There are many actors which accumulate to create this

eect. The installer needs to be aware that the temperature rise in the cabling at these points can be in the order o 10oC or higher when

all o these actors come together. The temperature rise created is greatest where:

l the cabling is managed into large bundles

l and/or there are a large number o simultaneous users

l and/or cabling is run into constricted spaces such as at wall penetrations

l and/or the cabling is required to support higher energy applications / PoE applications.

These heating eects can be mitigated by:

l reducing the bundle size

l loosening the bundle ties at points o constriction

l distributing the high energy use across dierent cable bundles

Cable InstallationFrom the cabling system design and oor plans make a cable pulling schedule. Map the pulling schedule onto the oor plans.

l Identiy the labels and cable ID so that temporary labelling can be applied.

l It may be aster, cheaper and more accurate to print two sets o the nal cable labels, using one set or installation purposes and then

replacing them ater testing is completed. This will avoid unsightly Pen Marks on the cable.

l Ensure that or each group o nished labels they are aligned and attached so they are readable rom the same direction.

l I the installation is a mixture o copper and bre optic cabling install the copper cabling rst.

l Plan the occupation o cabling in the containment and along the route so that crossovers are eliminated and entry points into andexits rom the containment are not congested.

l In any cable run where the cable is to be pulled the run should contain no more than two 90o bends. I more than two 90o bends are

required or the sum o all angles is greater than 180o then there must be more pull points along the cable run where the cable is able

to be managed in and out o the containment.

l Respect the installation bend radius o the cable. Never exceed the recommended maximum pulling load o the cables.

l Determine the pulling in points which will cause damage to the cable, though sharp edges or bends tighter than the installation

bend radius.

l Apply any protection to the containment where damage to the cable sheath may occur. Consider using cable

installation aids.

l Bundle size should be kept to a minimum.

l Maximum bundle size is 24 or 4 pair twisted copper cables.

l Smaller bundles make better use o limited containment space.

l With mixed length cables in a cable run always pull in the longest length cables rst.

l Secure the stack o cable boxes or reels using a pulling rame or cable stands to hold the packaging in place.

l Pulling orce must be respected. Maximum pull orce or a single, or bundle o cables, is 110 N (25 lb ).

l Avoid any cable kinks and maintain proper bend radius control during cabling pulling. I any kinks should occur, kinked cable should

be removed and replaced.

l For saety, only use cable jacks and pulling rames which are designed or and t or purpose.

l Always control the rate at which cables are pulled o the drum.


9/207

without compromise.

l Take great care over the management o cable drum.

l Hook and eye cable xings are preerred.

l I nylon type zip ties are used, cutting o long ends may cause the creation o razor sharp edges; do not over tighten.

l No deormation, marking or compression o cable jacket is allowed.

l Acclimatise the cables to the location where they are to be installed, minimum 2 hours.

l Reer to the specication sheet or the installation and operating temperature ranges or the cables being installed.

l The recommended installation temperature range is 0o 60oC (32o 140o F). Avoid pathways exposed to extreme thermal cycling.

l Remember that or some outdoor cabling there may be a minimum installation temperature.

l Do not install copper cabling or optical bre cabling with a metallic strength member outdoors when there is a thunder or

lightening storm about.

l Only use approved lubricants and pulling gels or the cable type being installed.

l For external installations seal the ends o all cables with a water tight product beore installation.

Earthing, Grounding and BondingUnless you are a qualied and competent electrical person leave the connection o the earthing wire onto the electrical system to the

electrical trade.

The best type o earthing conductor used to provide a signal earth connection is a at braided strap. Flat is best because it oers a

greater surace area and braided straps because impedance is aected by length and braid oers many dierent routes and thereore

lengths o conductor or the unwanted signals to ow along. I you use a solid core conductor to provide an earth strap you can improve

this by adding a second, dierent length, earth conductor to reduce the possibility o an impedance issue resisting the passage o the

unwanted signals.

Do not coil an earthing conductor around a screwdriver to make it look neat and tidy, you are orming a coil which can restrict the

transmission o signals.

It is best practice to connect the earth stud in a cabinet onto a separate earthing bar located in the cabinet. It is recommended that the

bar is provided with our or more attachment points or equipment earths to be connected onto. This is because i all o the equipment

earths are run back to the earth stud then or saety reasons the electrical supply must be disconnected every time a new piece o

equipment is added or removed rom the cabinet.

When installing a piece o equipment which requires a signal earth, always install the equipment, then attach the earth connection, then

connect up the power.

ESD (Electrostatic Discharge) can kill equipment. When installing equipment into a cabinet or rame always use an ESD strap connected

between you and the cabinet.

Each earthing conductor must be grounded onto a clean, purposeul earthing point. Use an approved cleaning method and bonding gel

to protect the joint rom oxidisation.

Do not daisy chain earthing conductors; the only exception to this is where there is a run o metallic cable containment when each

length must be grounded onto the next.

Example o Cabinet Earthing

The best practices or communications rooms and data centres recommend provision o an equipotential earthing grid or MESH-BN (a

bonding network in which all associated equipment rames, racks and cabinets and usually the DC power return conductor, are bonded

together as well as at multiple points to the Common Bonding Network).

This grid is used to earth all o the metallic components (rames, cabinets, oor tiles and pedestals, cable containment, etc) providing:

l a reliable signal reerence

l adequate immunity rom electromagnetic intererence carried by the earthing network

Each cabinet and rame must be provided with an earthing conductor made back to either the MESH-BN or home run back to the

main communications grounding bar within the room. For some installations this may be the electrical earthing bar in the main power

distribution board.

Cabinets and Framesl Install the cabinets and rames in the pre assigned positions.

l Check alignment o any containment with the cable entrances (or power and data) to the cabinet.

l Apply temporary labels to identiy the location.

l Secure the cabinets and rames to the solid oor and/or wall to provide stability when loaded with equipment

and cabling.

l Install any baying or joining components.

l Attach the earthing kit to all cabinet and rame components.

l Connect the main earthing conductor.

l Does the site require blanking panels or airow management in the cabinets and/or rames?

The layout or the inside o each cabinet should be determined in the overall site design. As with a lot o new designs there are great

pressures on the space available within the cabinets and rames. As a general rule or laying out a cabinet, begin at the top with the

patch panels starting with optical bre panels then copper panels. The top most position in a block o patch panels should be reserved

or a horizontal wire manager, then there should be no more than two patch panels o 1U height ollowed by another (or closing)horizontal wire manager. On high density rames the ront ngers o the vertical wire manager provide the support or patch cords

so there is not the same level o requirements or horizontal wire managers. Horizontal raceways will be required to acilitate shortest

routing between patch panel outlets.

l When installing panels and wire managers use all o the securing and xing holes provided.

Patch PanelsTermination procedures at the patch panel:

l Feed cables rom both sides o the panel

l Maintain acceptable bend radius levels

l Do not kink cables

l Do not do up cable ties so tightly as to deorm the cable in any way

To enhance wire management in the back o the panel, it is recommended that a strain relie bar is mounted to the rack. Along the strain

relie bar use hook and eye cable ties or additional cable management.

Termination procedures or the punch down patch panel:

l Follow installation instruction sheet

l Outer cable jacket should be trimmed to be as close as possible to point o termination

l Last twist should be no urther than 13 mm (0.5 inches) rom the point o termination.

without compromise.

Wall Boxes and Desk OutletsFor a duplex, twin outlet presentation, choose a back box that complies with the minimum bend radius o the cable.

I metal GOP boxes or metal ace plates are used, ensure that there is a grounding acility / earthing lug and a suitably sized earth wire

connection, with sufcient cable to earth the box and lid.

Colour codeThe colour code or punch down ollowed by Excel or all o their cabling system components is the T568B ormat.

Labels and AdministrationExcel recommends using the Sharpmark labelling solutions and templates. All Excel panels, outlets and aceplates are supported with

predened label layouts and ormats.

An administration system is required by the network owner to organise and control connections

and operation o their network and the associated support inrastructure. A ull and detailed

labelling scheme should be agreed beore the start o the installation. As a minimum this will

require labels and identiers being applied to cables, outlets, panels, cabinets and rames. For larger or more complex installations a

more comprehensive administration and labelling scheme is required. Best practices include labelling o items such as:

l Bonds unctional earth

l Cabinets, racks and rames

l Cables - both ends

l Closures

l Pathways

l Spaces

l Termination points including joints

l Cords/jumpers - both ends

Permanent Link DescriptionA Permanent Link is dened as the cabling between two outlets (or three outlets i a Consolidation Point (CP) or Local Distribution Point

(LDP) is used) but excludes any patch cords.

A Permanent Link, is the xed cabling, to which equipment and work area cords are added to complete the channel (see diagram below).

Physically the Permanent Link includes cable and outlets (possibly presented in a patch panel). Where a CP or LDP is required in the

Permanent Link the CP or LDP to Outlet cord and the outlet are to be included in the Permanent Link measurement and testing. There

are limits imposed within the standards or key electrical parameters such as insertion loss, XTALK, RL, ELFEXT, etc. The horizontal PL

must take into consideration all elements necessary to congure the operational channel, which has a limit o 100m (305t).

Channel Description

A channel is dened as the up to 100m connection between two active components.

Physically the channel includes horizontal cable outlets (possibly a patch panel), Interconnect (an out cables) and any cross connect

(patch cords), equipment or work area patch cords. There are limits imposed or key electrical parameters such as Attenuation, XTALK, RL,

ELFEXT, etc, the channel is not limited to a maximum o 4 connectors or junctions. However should a channel conguration require more

than 4 connectors then approval must be given, at design stage, by Excel or their warranty support.

Testing o a channel can take two orms:

l Condence test where the patch cords are removed or replaced ollowing the test

l Full test where the nal conguration is tested and let in place

A channel test serves to validate either conormity with the generic cabling standards or application support.

The term Reerence Cord is dened here as a new Excel patch cord that will only be used or up to 100 tests. Ater 100 tests the

Reerence Cord must be destroyed and replaced with another new Excel Reerence Cord.

Beore a Channel test is perormed all components in the Permanent Link must have been congured and validated or component

compliance.

Marginal or star passes on all other criteria are to be treated as ailures.
