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.
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.
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).
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.
Initial Power Up – continued Table 2-2: Initial Inspection and Setup Step Action 2 3 Confirm that the Meter Alarm Panel (MAP) POWER switch and all LEDs (Figure 2-9) are OFF. If any LEDs are lighted, re–check and turn OFF all battery shelf circuit breakers. 4 If a heat source was placed in the RF compartment to prevent condensation prior to BTS power–up, turn off the heat source and remove it and any associated cabling from the BTS before proceeding.

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.
Optimization/Calibration – Introduction – continued antenna feed line loss can be combined to determine the required power at the frame antenna connections. The corresponding BBX2 output level required to achieve that power level on any channel/sector can then be determined based on Bay Level Offset (BLO) data determined during the optimization process.
Preparing the LMF Overview Before optimization can be performed, the CDMA LMF must be installed and configured on a computer platform meeting Motorola–specified requirements (see Recommended Test Equipment and Software in Chapter 1). IMPORTANT * 3 For the CDMA LMF graphics to display properly, the computer platform must be configured to display more than 256 colors. See the operating system software instructions for verifying and configuring the display settings.
