Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature of the equipment (55C) 2. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. 3. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. 4. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on over current protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. 5. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips). 5-2 68P09277A59-8 PRELIMINARY - UNDER DEVELOPMENT MAY 2007 Access Point Hardware Installation Optional Band Pass Filters Optional Band Pass Filters ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Overview This chapter contains general information and procedures for installing optional equipment.

Otherwise, proceed to step 9 If more than one RF Head is in use tag the DC Power cable pairs using the color coded labels supplied inside the BCU Customer Interface compartment. Label the cables with the color coded tie-wraps as required. The cables are color coded as follows: • RFU 1 — Red • RFU 2 — Blue • RFU 3 — Yellow • RFU 4 — Green Place the color coded labels at the connector ends of both the DC power and Fiber Optic cables. 10 Loosen captive screws and ground lug from RF Head. Insert 6 AWG ground wire into ground lug and crimp in place. Reattach ground lug to RF Head. Attach opposite end of ground wire to tower ground. Do the same for the remaining RF Head ground lugs, as required. 11 Connect Fiber Optic Cables (color coded as well) to RF Head. Twist on connector until it stops (detent) 12 At this point, proceed to the Site Commissioning document for BCU and RF Head test information and operational verification. 13 The BCU and RF Head have been verified as operational, proceed with step 14. 14 Verify that the DC power cables are disconnected from the BCU. 15 Attach solar shield. Insert mushroom head knobs near bottom of shield into keyhole slots on sides of mounting bracket. Slide solar shield into position over handle and into slots on top of mounting bracket. Tighten screws to secure shield to brackets. 68P09277A59-8 MAY 2007 A-7 PRELIMINARY - UNDER DEVELOPMENT Manual RF Head Installation Procedures Appendix A: Alternate RF Head Installation Procedure Procedure A-2 Procedure to Prepare and Install RF Head (Continued) Install RF Head 16 Prepare the RF Head for hoisting. Attach carabiner to handle of RF Head. Use the block and tackle to hoist the RF Head to the Main Support Bracket Assembly. Carefully hoist RF Head up to Main Support Bracket Assembly. 17 Align to captive screws on side support bracket with the Main Support Bracket Assembly curved slots and drop into place.

Do not fully tighten screws. Refer to Figure A-3. 18 Ensure that the RF Head is properly mounted and its movement is not obstructed. Adjust the azimuth (up/down angle) loosen two M6 screws on each side of unit (if required, use a 10 mm socket or crescent wrench). Range of motion is 25 degrees from horizontal. The retention bracket serves as an indicator of the azimuth in degrees. When RF Head is set at the desired position, tighten captive screws on retention bracket. Torque bolts to 45 in-lbs (5.0 N-m). Tighten captive screws at pivot of each side of unit to secure RF Head. Torque bolts to 45 in-lbs (5.0N-m). 19 Use a 10 mm socket wrench to loosen ground lug captive screws on RF Head. Remove ground lug. Slide a 6 AWG wire into the ground lug. Crimp ground lug onto wire. Verify that 6 AWG wire is secure within ground lug. 20 Reattach ground lug onto RF Head. Use a 10 mm socket wrench to tighten captive screws. Torque screws to 45 in-lbs (5.0 N-m). Secure opposite other end of ground wire to tower ground. 21 Connect DC power cables to the RF Heads. Route DC power cables through conduit to bottom of the BCU and up into the BCU Customer Interface Compartment. Connect the cables to their respective RFU 1 — RFU 4 connectors by matching the tie-wrap color with the connector color. 22 Route Fiber Optic cables down the tower to the under side of the BCU. Connect cable to the appropriate FIBER feedthrough connector.

Be sure to factor in mounting considerations as described in Chapter 3 Cable Descriptions. The RGPS head must not make contact with any metal surface other than the provided hardware. Use only the equipment provided to mount the RGPS head. Failure to do so could damage the RGPS head. Procedure B-1 Procedure for Installing the RGPS Head and Cabling Determine the RGPS mounting location. The structure of the wall should be veried by a qualied structural engineer. 68P09277A59-8 MAY 2007 B-3 PRELIMINARY - UNDER DEVELOPMENT RGPS Cabling Installation Appendix B: Alternate RGPS Installation Procedure B-1 Procedure for Installing the RGPS Head and Cabling (Continued) Mounting the RGPS head and hardware to an inadequate wall structure and/or using inadequate installment methods can result in serious personal injury. Use the appropriate mounting bolts for the mounting surface and install the two wall mounting brackets. Refer to Figure B-3. Route the 12-pin Deutsch connector of the RGPS cable (C) through the RGPS mounting pipe. Connect the RGPS cable (C) connector to the RGPS head 12-pin connector as shown in Figure B-3 and Figure B-4. Tighten the spinning flange on the connector a quarter turn to secure the connection. Insert the RGPS mounting pipe into the threaded mount of the RGPS head and carefully hand-tighten. Install the RGPS mounting pipe into the mounting brackets as shown in Figure B-3. Tighten the U-bolt clamps to secure the assembly. Route the free ends of the BTS RGPS cable (L) and RGPS cable (C) to the lightning arrestor. Remove any excess cable length and strip off approximately 15 cm of the cables outer insulation. Connect the 12 individual connectors and cable drain of each cable end to the lightning arrestor as shown in Figure B-5. Double check the lightning arrestor connections for compliance with those presented in Figure B-5. Route the RGPS cable from the lightning arrestor to the bottom of the BCU. 10 If not already open, open the Customer Interface compartment. If not already done, remove access hole cover. 11 Route the RGPS cable up through the access hole and connect to RGPS D-Connector.
