2.6 Replacement of BTS Resource Distribution Module
(BRDM)
I. Note
1)
The replacement of a BRDM will interrupt the current service processed by the
BRDM.
2)
BRDM should be anti-static, therefore operations should be made strictly based
on operation procedures. That is to say, wear an anti-static wrist strap and
gloves and make the grounding terminal well grounded to prevent any static
electricity damaging the board.
II. Replacement Details
1)
View the BRDM alarm and block a corresponding BTRM
Connect a portable computer with the local-end maintenance software with the
Ethernet interface of a base station BCKM and switch on Telnet to log on to the base
station. Then, view and record the fault type and software/hardware versions of
BRDM.
For a BTRM whose services will be interrupted, execute the command of "BLK
BTSCELL" with right parameters or shut off its power.

Unplug the BRDM
Remove the optical fiber and record its optical interface location. Then, pull the BRDM

corresponding optical interface location.
