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 with a maximum of 4 carriers, 3–sectored with a maximum of 4 carriers, and 6–sectored with a maximum of 2 carriers.
Preliminary Operations: Overview – continued Setting Frame C–CCP Shelf Configuration Switch If the frame is a Starter BTS, the backplane switch settings behind the fan module should be set to the ON position (see Figure 2-1). 2 The switch setting must be verified and set before power is applied to the BTS equipment.
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 cellsite and BTS power supply units before applying power for the first time. It contains instructional information on the initial proper power up procedures for the SC 4812ET power cabinet and RF cabinet. Also presented are tests to be preformed on the power cabinet.
Initial Power Up – continued CAUTION Failure to connect the proper AC feed will damage the surge protection module inside the AC load center. 2 Power Up Sequence The first task in the power up sequence is to apply AC power to the Power cabinet. Once power is applied a series of AC Voltage measurements is required.
Initial Power Up – continued Figure 2-2: AC Load Center Wiring 2 G N L1 L2 = Ground = Neutral = Line 1 = Line 2 G L1 N L2 AC to Pilot Beacon FW00305 Applying AC Power Once AC Voltage Measurements are complete, apply AC power to the Power Cabinet. Table 2-4 provides the procedure for applying AC power.

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 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. If the TX calibration fails, repeat the full optimization for any failed paths. If the TX calibration fails again, correct the problem that caused the failure and repeat the full optimization for the failed path.
Optimization/Calibration – Introduction – continued BTS System Software Download BTS system software must be successfully downloaded to the BTS processor boards before optimization can be performed. BTS operating code is loaded from the LMF computer terminal. IMPORTANT * Before using the LMF for optimization/ATP, the correct bts–#.cdf and cbsc–#.cdf files for the BTS must be obtained from the CBSC and put in a bts–# folder in the LMF. Failure to use the correct CDF files can cause wrong results.
Isolate Span Lines/Connect LMF Isolate BTS from T1/E1 Spans IMPORTANT * – At active sites, the OMC/CBSC must disable the BTS and place it out of service (OOS). DO NOT remove the span surge protectors until the OMC/CBSC has disabled the BTS. Each frame is equipped with one 50–pair punch block for spans, customer alarms, remote GPS, and power cabinet alarms. See Figure 3-2 and refer to Table 3-1 for the physical location and pin call–out information.
Isolate Span Lines/Connect LMF – continued Setting the Control Port Whichever control port is chosen, it must first be set up so the control port switches match the communication parameters being used by the control device. If using the rear–panel DTE control port, set the shelf–address switch SA5 to “up” (leave the switch down for the rear–panel DCE control port).
Isolate Span Lines/Connect LMF – continued CAUTION SC4812ET Span Line Labeling for Span B and Span C is swapped – On the SC4812ET’s, the span cabel internal to the base station that connects the 50 pin header on the I/O plate to the CSU has Span B and Span C (RJ–45) connectors mis–labeled. – CFE will punch down the span on the 50 pair bunchblock as per Motorola documentation and punchdown chart. When conecting the span input to the CSU re–label “Span B” cable to”Span C” cable to “Span B”.
