5 Mount the replacement chassis.
While supporting the chassis, slide the chassis into the cabinet mounting position. Secure the
chassis to the cabinet mounting rails using the four mounting screws provided with the unit.
Tighten the screws to 4.5 Nm (40 in-lb).
6 Reconnect the cabling to the replacement chassis as defined in Step 2.
Use the SMA torque wrench for all SMA connectors.
7 Using the breakers on the PDU, turn up the BIC, AIC, and RBS 1 (and RBS 2 and RBS 3 if
present), and then verify that the components are operational before proceeding.
Wait approximately 3 minutes for the following indicators:
• RBS: The STATUS LED for each group will light green in this order: A, B, and then C.
• RBS: The RADIOBLADE STATUS LEDs will light red and then green for each present
RadioBlade. If no RB is present, the LED will not light. To verify the contents of the RBS,
pull out the shelf (powering off is not required) and inspect the RadioBlades and their
respective status LEDs. Reinsert the RBS. To do this, press up on one side rail locking
arm and press down on the other side rail locking arm, and then push the unit into the
rack (see the following illustration).
• BIC CRIC and AIC CRIC: The POWER and STATUS LEDs will light red and then green.
All other BIC and AIC card LEDs will light green.
8 Using the breaker on the PDU, turn up each RF Shelf and then verify that each RF Shelf is
operational before proceeding. The POWER and ALARM LEDs on the front of the RF Shelf
will light green.
9 Complete the procedures in sections 5.4, 5.5 and 5.6.
7.9.2.3 RBS 1 (power down RBS 2 and RBS 3 if they are present)
1
Power down RFN equipment in the following order using circuit breakers on the PDU:
• BIC
• AIC
• RBS 1 (power down RBS 2 and RBS 3 if they are present)
• RF Shelves 1,2 and 3
2 Disconnect cabling from the back of the RBS to be replaced.
For RBS 1, disconnect the following cabling from the rear of the RBS 1 only:
NOTE: If RBS 2 and RBS 3 are present, refer to Appendix C Cabling Diagrams: 3-Sector
Configuration and Appendix D Cabling Diagrams: Omni Configuration.
