BTS Field Maintenance 113
Step 12
Monitor the bootup process, refer to Chapter 4 for procedures.
Step 13
Inform the OMC operator to unlock the BTS object using the OMC and verify that the WAVEXpress/
BTS has been returned to its on-line status: operational, unlocked, online.
Step 14
Conduct test calls on all TRX channels contained in the WAVEXpress/BTS.
A2-1.3 Replacing the WAVEXpress/BTS TRX card
This section contains the procedures for replacing the TRX card on a WAVEXpress/BTS. Refer to Figure A2-1
"WAVEXpress/BTS field replaceable units" on page 108 for an illustration of the replacement position.
TRX cards can be replaced without powering off the WAVEXpress/BTS. If the WAVEXpress/BTS contains multiple TRX
cards, replacing one TRX card will not effect existing calls when calls do not exceed the capacity of the remaining TRX
card(s). New calls will also be processed if the capacity of the remaining TRX card(s) has not been exceeded.
Step 1
Inform the OMC operator to lock the faulty TRX card from the OMC.
Step 2
Ensure that anti-static precautions are taken.
Step 3
Using a torque wrench (set to 8 in. lbs.), disconnect the RF semi-rigid cables connecting the TRX card
to the RF distribution card. Refer to the following illustration for the appropriate cables to disconnect:
WHEN REPLACING A TRX CARD ON A ONE TRX WAVEXPRESS/BTS SYSTEM,
SERVICE WILL BE INTERRUPTED AND NEW CALLS WILL NOT BE PROCESSED
UNTIL A NEW TRX CARD IS REPLACED
.
NOTE
☛
TRX cards take up two card slots and are placed from right to left starting with slots 6
and 7 on the WAVEXpress/BTS chassis.
