The BS mounting hardware is composed of the following: – downtilt adjustment screws, – flat washers, – lock washers, – antenna bolts, – U-bolts and U-bolt brackets, – 17 mm nuts. The dual antenna mounting plate can accommodate either one or two antennas. Single-antenna configurations are used for non-redundant X-Pol RBS Tx or X-Pol RBS Rx operation, and double- antenna configurations are used for redundant X-Pol RBS Tx or X-Pol RBS Rx operation. To connect a mounting plate and antenna to a pole 1. Attach the mounting plate to the pole using the pole mounting hardware, as shown in Figure 12, where a single antenna mounting plate is shown. 1. Thread the downtilt adjustment screw(s) into the mounting plate until the hole in the adjustment screw plate aligns with the antenna bolt channel at the top of the mounting plate. 2. Connect the top of the mounting plate to the pole using a U-bolt, U-bolt bracket, washers and nuts. 3. Tighten the two nuts until the top of the mounting plate is held securely to the pole, but is still shifts enough from side-to-side to allow the bottom U-bolt to be inserted. 4. Connect the bottom of the mounting plate to the pole using a U-bolt, U-bolt bracket, washers and nuts. 5. Tighten all four U-bolt nuts to 54.4 Nm, ± 2.7 Nm (40 ft-lb, ± 2 ft-lb) of torque. Warning - If an antenna is attached to a mounting plate on a pole before an X-Pol RBS Tx or X-Pol RBS Rx is attached to the antenna, the RF wave guide and screws must be covered with weatherproof tape to protect the antenna from moisture. Caution - Do not install an X-Pol RBS Tx and an X-Pol RBS Rx on the same mounting plate, otherwise the X-Pol RBS Tx transmit signal will interfere with the X-Pol RBS Rx receive signal. Caution - Mounting poles should be grounded to a suitable lightning discharge ground. 3CC12426AAAA TQ BJA 01Issue 01 - April 2001 - Draft 0443/346 104 Figure 12 – Connecting the mounting plate to the pole 2.

Set the DMC crimping tool to position 4 (for 24 AWG wire), and give the positioner a clockwise twist to ensure that it is set properly and will crimp the contact pins on four sides. 10. Place a contact pin on a lead and check that the lead is inserted completely by looking in the hole in the contact pin; see Figure 51. There should be no more than 1 mm (0.04 in.) of exposed conductor protruding from the pin. Insert the pin into the DMC tool as far as it can go, and crimp the pin. The DMC tool has a ratchet mechanism that does not release until the pin has been crimped properly. Repeat this step for each lead. Figure 51 – Attaching a contact pin 11. Arrange the four pins as indicated in Figure 52, and insert them simultaneously into the insert; the pins enter the side of the insert that has the white marking. The pins must be inserted simultaneously because the conductors are not long enough to be inserted one at a time. Push each pin until it clicks into position, then confirm that contact is secure by gently pulling on the conductor. The white marking on the insert identifies the pins. The white circle identifies pin 1, and pins 2, 3 and 4 follow counterclockwise. Use the removal tool if the pins are in the wrong holes. Figure 52 – Inserting the contact pins 12. Put the insert into the insert carrier; see Figure 53. When assembled properly, the tab on the carrier faces towards the pins, the tab on the insert fits in the cutout in the carrier, and the bevel in the carrier fits on the bevel on the cone washer. The mat- ching bevels pinch the braided shielding when the connector is completely assembled.

All tools and hardware required for this procedure except wrenches and soldering tools should be ordered from Heliax. See Appendix A for details. 2.9.2 – To add a solder-connect L4PNM connector 1. Strip 51 mm (2 in.) or more of the cable jacket from the IF cable, ending at the lowest point of a valley between two corrugations, as shown in Figure 56. Figure 56 – Removing the insulation 2. Install the O-ring on the first corrugation valley as shown in Figure 57. Figure 57 – Installing the small O-ring Note - Newbridge Broadband Wireless equipment should only be installed by qualified individuals who are trained and certified for the type of installation task assigned to them. Note - This step can be done more accurately and quickly if Heliax cable tool 207886 is used to score the cable jacket and cut the outer conductor. 51 mm (2 in.) or greater Outer conductor Lowest point between corrugations O-ring Cable jacket 84/346Issue 01 - April 2001 - Draft 043CC12426AAAA TQ BJA 01 104 3. Use a small grease brush to lubricate the O-ring with the silicone grease shipped with the connector. 4. Install the clamping nut on the cable by sliding it over the cable end until it is stopped by the O-ring. The fingers of the clamping nut should stop exactly half-way through a corrugation peak, as shown in Figure 58. Figure 58 – Installing the clamping nut 5. Remove the portion of outer conductor that is not covered by the clamping nut. 1. Use a fine-tooth saw to cut through the outer conductor flush with the clamping nut fingers. Do not cut deeper than the outer conductor, and make sure that the cut is made along the entire circumference where the clamping nut fingers meet the outer conductor; see Figure 59. Figure 59 – Cutting the outer conductor 2. Grasp the outer conductor with pliers, and carefully pull it off. When removed, the foam dielectric is exposed, as seen in Figure 60. Figure 60 – Foam dielectric Note - Substep i is unnecessary if Heliax cable tool 207886 was used in step 1 to score the cable jacket, and cut the outer conductor.

Remove the foam dielectric from the inner conductor. 1. Use a knife to cut the foam dielectric flush with the outer conductor, to the depth of the inner conductor, then cut along the length of the inner conductor several times until all the foam dielectric is removed from the inner conductor; see Figure 61. Figure 61 – Removing the foam dielectric 2. Use a knife to carefully scrape any remaining dielectric foam adhesive from the inner conductor. Be careful not to damage the inner conductor. 7. Trim the inner conductor. 1. Use a fine-tooth saw to trim the inner conductor to 5 mm (7/32 in.) from the outer conductor and clamping nut fingers, as shown in Figure 62. 2. Use a small file to remove any burrs on the end of the inner conductor. 3. Use a clean wire brush to remove any debris from the foam dielectric. 86/346Issue 01 - April 2001 - Draft 043CC12426AAAA TQ B…

Do not obstruct the air inlets and outlets. Stages 1. Choose the location where the equipment is to be assembled and unpack the standard rack. If its top cover is fitted, remove it (quarter-turn screw). Note:place the rack in such a way that the cable connections are accessible before the rack is installed definitively. 2. Unpack the DBS chassis assembly and install it inside the rack. Fix and screw into place. 3. Unpack the DC/DC PSUs; install and plug them in the DBS chassis. 4. Carry out the electrical connection, cf. § 3.4.2 – Electrical connection. 5. Carry out the client terminal connections, cf. § 3.4.3 – Customer access connections (circuits interfaces) and 3.4.4 – Client access connections (ATM network interface). 6. Connect the X-Pol RBS/DBS connection cable(s). 3.4.2 – Electrical connection Considerations – The DBS chassis is supplied from the rated DC voltage of 48 V (minimum 35 V, maximum 60 V). – The cable connecting the external DC power source to the DBS sub-rack will have a minimum cross-section of 3x10 mm 2 and a maximum length of 20 meters. – The rack must be grounded to the general grounding system. For this, the rack mechanism will be connected by a cable with a minimum cross-section of 16 mm 2 , attached using a 6 mm bolt. – For the power supply block diagram, refer to Figure 90 – DBS chassis power supply: Figure 90 – DBS chassis power supply WHEN MAKING THE POWER CONNECTIONS, TURN OFF ALL DBS CHASSIS EXTERNAL POWER SOURCES 0V/+48V –48V/0V Grounding Fuse holder ON – OFF switch Fuse cartridge GRC 14x51 40 Am p. 114/346Issue 01 - April 2001 - Draft 043CC12426AAAA TQ BJA 01 128 Note:The user can connect +48 V or -48 V to ground. Stages (Figure 92 – DBS sub-rack power connection) 1. Connect the switch at the top of the DBS sub-rack to the external DC power source. You are recommended to pass the power supply cable via the top of the rack. 2. Ground the DBS sub-rack. Note:a ground strip is fixed to the backplane and ensures its grounding. The rack and subrack ground are screwed together, thus no special grounding is required for the rack. Figure 91 – DBS sub-rack ground connection Earthing must be done very carefully in order to assure good operation of the DBS. 3. Make sure that the fuses are inserted in the fuse-holder. Before changing fuse, make sure that the switch is set to OFF.

Note:the provided equipment is already connected and parts of the installation kit. 3.4.3.1 – Direct connections to the connectors of the top panel of the DBS chassis. Note:All connectors are female connectors.
