Prepower-up 68P09255A57-2 Prepower-up 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. 2 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.
Prepower-up 68P09255A57-2 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). The switch setting must be verified and set before power is applied to the BTS equipment.
Prepower-up 68P09255A57-2 Required Tools The following tools are used in the procedures. DC current clamp (600 Amp capability with jaw size to accommodate 2/0 cable).
Prepower-up 68P09255A57-2 Table 2-3: AC Voltage Measurements Step Action 3 Measure the AC voltage from terminal L1 to ground. This voltage should be in the range of nominally 115 to 120 Vac. 4 Measure the AC voltage from terminal L2 to neutral. This voltage should be in the range of nominally 115 to 120 Vac. 5 Measure the AC voltage from terminal L2 to ground. This voltage should be in the range of nominally 115 to 120 Vac. 6 Measure L1 - L2 - should be from 208 to 240 Vac.
AC Power Up Sequence 68P09255A57-2 AC Power Up Sequence 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. 2 Table 2-4: Applying AC Power Step Action 1 When the input voltages are verified as correct, turn the Main AC breaker (located on the front of the ACLC) ON. Observe that all eight (8) green LEDs on the front of the ACLC are illuminated (see Figure 2-7).
AC Power Up Sequence 68P09255A57-2 Power Cabinet Power Tests Table 2-5 lists the step-by-step instructions for Power Up Tests. Table 2-5: Power Cabinet Power Up Tests Step Action 2 1 Probe the output voltage test point on the Meter Alarm Panel while pressing the 25° C set button on the TCP (see Figure 2-4). The voltage should read 27.4 + 0.2 Vdc. Adjust Master Voltage on Meter Alarm Panel if necessary. Release the TCP 25° C set button.
DC Power Pre-test 68P09255A57-2 DC Power Pre-test DC Power Checks Before applying any power to the BTS cabinet, verify there are no shorts in the RF or power DC distribution system (see Figure 2-5). 2 Table 2-6: DC Power Pre-test (BTS Frame) Step Action 1 Physically verify that all AC rectifiers supplying power to the RF cabinets are OFF or disabled (see Figure 2-5). There should be no 27 Vdc on DC feed terminals.

LMF Operation 68P09255A57-2 LMF Operation Preparing the LMF Before optimization can be performed, the LMF application software must be installed and configured on a computer platform meeting Motorola-specified requirements (see Recommended Test Equipment and Software in Chapter 1). NOTE For the 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.
LMF Operation 68P09255A57-2 Table 3-3: LMF Operating System Installation Step Action * IMPORTANT First Time Installations: - Install U/WIN (First) - Install Java Runtime Environment (Second) - Install LMF Software (Third) - Install BTS Binaries (Fourth) - Install/Create BTS Folders (Fifth) Any time you install U/WIN, you must install the LMF software because the installation of the LMF modifies some of the files that are installed during the U/Win installation.
LMF Operation 68P09255A57-2 NOTE When copying CDF files, comply with the following to prevent BTS login problems with the LMF. - The numbers used in the bts-#.cdf and cbsc-#.cdf filenames must correspond to the locally assigned numbers for each BTS and its controlling CBSC. - The generic cbsc-1.cdf file supplied with the LMF will work with locally numbered BTS CDF files. Using this file will not provide a valid optimization unless the generic file is edited to replace default parameters (e.g.
