Initial Power–up Tests and Procedures – continued
2-12 1X SC 4812T Lite BTS Optimization/ATP FEB 2005
PRELIMINARY
Initial Power-up (BTS)
The procedure in Table 2-4 must be performed on each BTS Frame after
Input Power from the common Power Supply Module has been verified.
Perform the procedure in Table 2-4 to apply initial power to the
cards/modules within the frame itself, verifying that each is operating
within specification.
Table 2-4: Initial Power–up (BTS) Procedure
n Step Action
1 At the BTS, set the SCCP Power Distribution Circuit Breakers to the ON position by pushing in
the circuit breakers.
– Refer to Figure 2-4 on Page 2-9.
2 Insert the SCCP Fan Modules.
– Verify that the Fan Modules come on line.
! CAUTION
Verify that the correct SCCP Power Supply Modules are being used by checking the markings on
the Locking/Retracting Tabs. Make sure that the markings appear as follows:
STPN 4009B
PWR C–CCP 4812 +27V
3 Insert and lock the Power Supply Modules into their associated slots one at a time.
– If no cards are installed in the SCCP Cage, the PWR/ALM LEDs on all three Power Supply
Modules appear RED to notify the user that there is no Load on the Power Supply Modules.
– If the LED is RED, do not be alarmed. After Step 3 is performed, the LEDs should turn
GREEN; if not, then a faulty Power Supply Module is indicated and should be replaced
before proceeding.
3 Seat and lock all remaining cards and modules in the SCCP Cage into their associated slots.
4 Seat the first equipped LPA Module Pair into the assigned slot in the upper LPA Shelf, including
the LPA Fan.
5 Repeat Step 4 for all remaining LPA Module Pairs.
! CAUTION
On frames that have CLPA Modules, engage the circuit breakers in pairs as marked on the Circuit
Breaker Panel.
NOTE
Engage the circuit breakers only for the LPA Modules that are equipped.
6 Set the LPA Circuit Breakers to the ON position (per configuration) by pushing them IN.
– Confirm that the LEDs on LPA Modules light GREEN.
– Refer to Figure 2-4 for the Circuit Breaker Panel Layout.
