1 Overview

The ClearLink UDIT is a modular, scalable sub-system which provides RF conditioning between the BTS and the DAS for single carrier or neutral host multicarrier/operator systems. The ClearLink UDIT chassis is capable of supporting 13 modules; a controller/power supply and up to 12 UDIT POIs or UDIT Combiner modules. The chassis and all UDIT modules are designed with their cabling interfaces accessible on the front panel. This arrangement provides the system maximum flexibility to meet the specific installation needs.

1.1 Customer Furnished Equipment

The UDIT chassis can be rack mounted in a 19” two (2) post rack using center mounted hardware or flush mounted in a four (4) post rack. Table 1-1 list the tools and supplies that you will need to have for the installation and maintenance of the UDIT system.

Table 1-1: Tools and Supplies Required

Ground Wire No. 6 AWG

Flat tip screwdrivers #1, #2, #3

Phillips screwdrivers #1, #2, #3, #4

Torx Screwdriver T10

Side Cutters N/A

Wire/Cable Strippers N/A

Razor Knife N/A

Torque Wrench 7/16 DIN

Crimper for Ground Lug

Electrical Tape N/A

Velcro 0.75” width

Hook and Loop Cable Tie ¾” width

1.2 Prepare the Site

Select an appropriate location within your rack for mounting the UDIT chassis. Please consider the high heat load of the unit and its requirements as well as the availability of the required power. Some acceptable locations include; telecom closets, MDF rooms, and climate control enclosures. The area must also be capable

of providing at least a 10” unobstructed area behind the unit to avoid cooling fan airflow restriction.

Local Code Requirements should be followed. Always review the local code requirements with the local Authority Having Jurisdiction (AHJ) before proceeding with the installation. This includes reviewing what codes and edition is adopted, and what, if any exceptions to the code are adopted by the governing authority. Most of the code requirements for the job should be included in the scope of work documents. The installer should never take this information for granted since the telecommunications contractor is fully responsible for all work

done on the project.

If no code has been adopted locally, consult with the fire marshal’s office to determine what agency is responsible for that geographic area and what codes are in effect. Do not depend on other installers, contractors, or even company personnel in making these determinations.




Local DAS Requirements

In 2010 the National Fire Protection Association (NFPA) adopted an updated version of their code NFPA-72, the National Fire Alarm Code, which includes a requirement for DAS or other In Building Wireless (IBW)

systems in certain commercial buildings to provide coverage for public safety radio systems. A growing number of cities and states are adopting this or a similar code, making such coverage mandatory. The specifics of these ordinances and codes vary, but most include: A minimum signal strength, application of the limit over a specified percentage of each floor, a specific level of reliability, a specific frequency band or bands for public safety coverage, testing requirements and procedures, provisions for penalties, provisions for waivers of the requirements.

1.2.1 High Heat Loading Considerations

Due to the high density construction of the chassis and ability to handle up to 100W of RF power per POI, care needs to be taken to accommodate for the potentially high heat loading of the area in which it will be installed.

Table 1-2 shows an example of the heat calculation for a single chassis with 12 POI units.

In cases where a large number of units are installed in a limited area, additional cooling may be required to avoid hot spots and excessive temperature gradients in the room. For additional information on equipment and room cooling methods, refer to GR-3028-CORE, Thermal Management in Telecommunication Central

Offices: Thermal GR-3028.

7 Connecting the Power Source

Each UDIT Sub-Rack requires an NRTL approved DC power supply to provide the required range of -36 to -60VDC (-48VDC nominal), 3.6 - 6.1A (4.0A nominal, 220w maximum). The UDIT Control/Power Supply Module ships with 20 AWG wire. The user should use a wire size between 16 and 22 AWG.

7.1 Power Consumption Calculations

Table 7-1 lists the typical power consumption for each component in the UDIT family. This data should be used to determine the total current draw for the -48VDC power supply and associated backup power system.

Table 7-1: Typical Component Power Consumptions

Component Power Consumption Watts

(Typical at -48VDC)

Chassis with Controller Module 10 – 75.0 (temperature dependent)

Controller Module 9.6

POI Module 7.0

Combiner Module 1.0

NOTE

The -48VDC supply is fully isolated from chassis ground. DC Power is classified as DC-I per GR-1089.




7.2 Power Installation

Follow the steps in Table 7-2 for the installation of the power to the UDIT chassis.

Table 7-2: Power Installation


1 Make sure power supply is off or fuse is removed on fuse panel as appropriate.

2 Connect open end of power cable to -48VDC power supply or fuse panel, if

required

Depending on which style Control/PSU module you have you will have a two wire cable open on one end and terminated with either a green Phoenix connector or ring connectors

NOTE: The Return and -48VDC positions of the connector as labeled on the UDIT Control/PSU module

Red: RTN (RED wire)

Black: -48VDC (Black wire)

3 Turn on power supply and check with multi meter to be sure -48VDC is supplied properly





4 If the Control Module has a Green Phoenix Power Connector, UDIT has shipped with a 20 AWG cable terminated with a Phoenix connector on one end. Plug the green power connector into the Control/PSU module mounted in the UDIT

chassis and secure using the screws in the connector.

If the Control Module has the Terminal block, UDIT has shipped with a 20 AWG

wire with ring lugs. Attach each ring terminal to its respective post and secure

with the included hardware, making sure to maintain proper power orientation.

Properly terminate the open end of the wires and secure to your power supply or fuse panel.

Do not use spade lug connectors or bare wire to make these connections.

5 Turn on the power or insert fuse in fuse panel as appropriate





6 When power is first applied the LED’s on the POI’s will light green during boot up

The POI’s then turn red until the cabling between the BTS through the UDIT to the DAS are properly cabled

and RF is applied

At this point the POI LED’s will again turn green

The Control/PSU Power LED will turn Green

The Control/PSU Status LED will start Orange while the system performs

diagnostics and then will be Red if there is an alarm or green if there are no alarms

LED on Combiner will turn Red if there is any alarm for the Combiner

NOTE: If the LED on the POI does not turn on during power up check to make sure the module is seated correctly. If the LEDS do not turn green check the cabling to make sure that it is connected correctly.




8 Cabling and Cable Management

The slots in the Cable Manager allow flexibility in securing BTS and DAS cables. Cables can be routed from the front of the UDIT Chassis to the rear of the rack or up/down the front of the UDIT Chassis and across Cable Managers mounted above and below the UDIT. The UDIT is designed such that a cable connected to a lower position DIN connector routes up and a cable connected to an upper position DIN routes down.

NOTE

Cables should be installed such that they will not interfere with the installation

or removal of a POI into any slot, nor block the rear fans.

NOTE

When installing cables it is important to maintain the bend radius of the cables. Refer to the manufactures specifications for specific cable bend radius.

NOTE

QMA jumpers should be of a flexible cable such as RG142 or equivalent. Users should not use an N to QMA adapter on an inflexible cable such as LMR400, or LDF4 as this could damage the QMA connectors on the UDIT modules.

8.1 Cable Manager Installation

Follow the steps in Table 8-1 for the installation of the Cable Managers above and below the UDIT chassis.

Table 8-1: Cable Manager Installation


1 Use four (4) Phillips screws to mount the upper Cable Manager above the UDIT chassis such that there is 1U space between the top of the UDIT and

the bottom of the Cable Manager, with the CSI logo in an upright position

NOTE: This will allow the 7/16 DIN connectors to fit between the UDIT chassis located above or below the cable managers

2 Use four (4) Phillips screws to mount the lower Cable Manager below the UDIT chassis such that the

top of the Cable Manager bracket is right under the UDIT chassis, with the CSI logo should be in an upright position

3 Remove the dust caps from the front of the POI and Combiner modules





4 Refer to Sections 8.2 and 8.3 for connecting and routing the cables properly

8.2 BTS Connections

To enable the BTS cables to meet bend radius requirements and allow access to adjacent POIs, the BTS cables can be routed from the back and fed:

Over the UDIT chassis and under the upper Cable Manager and connected to a lower DIN connector

Under the UDIT chassis and over the lower Cable Manager and connected to an upper DIN connector

Secure the BTS cables to the Cable Manager using a Velcro strap fed through two slots parallel to the cable run.

NOTE

The UDIT POI Modules are designed to fit in the chassis in alternating directions to allow the installer to be able to use a 7/16” DIN torque wrench to

properly tighten the DIN connector.

8.3 DAS Connections

QMA cables that feed the DAS can be routed along and secured to the BTS cables with Velcro straps. These cables may connect to a DAS whose connections may be on the front or rear of the rack.

NOTE

The UDIT requires QMA cables, the DAS may use a different connector. Be sure to have the proper type and length cables and adapters as required for the installation.

For front DAS connections route the QMA cables from the UDIT, along the BTS cables and across the

Cable Manager

o Secure the cables using the front slots and Velcro straps

o The cables then can route up or down using installer provided vertical managers to the DAS




For rear DAS connections route cables along the BTS cables from the front to the rear of the UDIT

chassis

o At the rear of the chassis be sure BTS and DAS cables sweep to the right or the left and route

along the rack rails or in the installer provided vertical cable manager

o Cables should not block fans to allow for proper cooling and replacement

8.4 Combiner Connections

QMA to QMA cables are used to connect POI UL and DL ports to Combiner UL and DL ports

Use the color coded port labels to assist in making connections to combine up to 4 POIs

o UL – Blue

o DL - Green

Up to four (4) POIs can be connected to a Combiner

Not all ports need be connected on a Combiner

Unused ports should be terminated with a 50Ω termination

The middle UL and DL ports connect to the DAS




9 Preventive Maintenance

The overall preventive maintenance is based on checking the LEDs on the front of the modules and components, as well as regularly checking to make sure everything is in working order.
