BTS Equipment Identification 1 Equipment Overview The SC4812ET Lite BTS frame consists of a single, outdoor, weatherized cabinet containing RF and power components. The BTS is functionally similar to the two–cabinet SC4812ET, but provides more flexibility in site selection because of its smaller footprint and lighter weight. The BTS is powered by 240 Vac, rectified internally to +27 Vdc, and can support up to two carriers in a 3–sector configuration.

Preliminary Operations: Overview Introduction This section first verifies proper frame equipage. This includes verifying module placement, jumper, and dual in–line package (DIP) switch settings against the site-specific documentation supplied for each BTS application. Next, pre-power up and initial power-up procedures are presented. Cellsite Types Sites are configured as 3–sector with one or two carriers. Each type has unique characteristics and must be optimized accordingly.
PAGE 58
Preliminary Operations: Overview – continued Setting Frame SCCP Configuration Switch The backplane configuration switch is located behind the frame rear access panel. It must be set for the frame type as shown in Figure 2-1. 2 The switch setting must be verified and set before power is applied to the BTS equipment.
PAGE 59
Ethernet LAN Ethernet LAN Termination For proper operation, each end of the primary and redundant BTS Ethernet Local Area Networks (LAN) must be terminated with a 50–ohm load. For a BTS consisting of a single frame, this is done by placing 50–ohm triaxial terminations on the LAN A and B external IN and OUT connectors located in the power entry compartment (Figure 2-2).
PAGE 60
Initial Power Up Introduction The following information is used to check for any electrical short circuits and to verify the operation and tolerances of the cell site and BTS power supply units before applying power for the first time. It contains instructional information on the proper initial power up procedures for the SC4812ET Lite for both the North American version and the International version. If directions are different for either version, they are called out within the procedure.

S In the frame LPA compartment, disconnect the Linear Power Amplifier (LPA) cables from the compartment bulkhead feed through connector.

Initial Power Up – continued Table 2-3: DC Power System Pre–Power Application Test Step 14 Action 2 Carefully reconnect each LPA cable one at a time. Repeat step 10 after reconnecting each cable. S A typical response is that the ohmmeter will steadily climb in resistance as module input capacitors charge, finally indicating between 300 Ω minimum and 900 Ω. maximum. 15 Set the Pilot Beacon, both Heat Exchanger, ETIB, and Options circuit breakers to ON one at a time.

CAUTION North AMERICAN Cabinet only: If the AC voltages measured in the following steps exceed 120 V when measuring from terminals L1 or L2 to neutral or ground, STOP and DO NOT proceed until the cause of the higher voltages are determined. The frame will be damaged if the Main breaker is turned on with excessive voltage on the inputs. Measure the AC voltage from terminal L1 to neutral.

Initial Power Up – continued Table 2-5: Applying Internal AC Power Step Action 2 3 Be sure the MAP power switch, TCP switch, and BATT TEST switch are all set to OFF. 4 If it has not already been done, set the facility circuit breaker supplying AC power to the frame to ON. 5 Set the ACLC MAIN circuit breaker ON. S For the North American cabinet: Observe that all eight (8) green LEDs on the front of the ACLC are illuminated (Figure 2-4).

Initial Power Up – continued Table 2-6: DC Power Application and Tests Step 10 Action Confirm that the MAP AMP display continues to indicate between 20 and 60 amps during the initial power application. NOTE No battery charging or heavy RF loading is present at this point. 11 If the frame is not equipped with the pilot beacon option, set the PILOT BEACON circuit breaker to OFF.

Initial Power Up – continued Table 2-7: Battery Charge Test (Connected Batteries) Step 2 Action 3 The current in each string should be approximately equal (within + 5 amps). 4 Allow a few minutes to ensure that the battery charge current stabilizes before taking any further action. Recheck the battery current in each string. If the batteries had a reasonable charge, the current in each string should reduce to less than 5 amps. 5 Recheck the DC output voltage.

Optimization/Calibration – Introduction Introduction This chapter provides procedures for downloading system operating software, set up of the supported test equipment, CSM reference verification/optimization, and transmit/receive path verification. IMPORTANT * Before using the LMF, use an editor to view the ”CAVEATS” section in the ”readme.txt” file in the c:\wlmf folder for any applicable information.

Optimization/Calibration – Introduction – continued S Select all of the BBXs and all of the MCCs and use the full optimization function. The full optimization function performs TX calibration, BLO download, TX audit, all TX tests, and all RX tests for all selected devices. S If the TX calibration fails, repeat the full optimization for any failed paths. S If the TX calibration fails again, correct the problem that caused the failure and repeat the full optimization for the failed path.
