2.5 Replacement of BTS Control & Clock Module (BCKM)
I. Note
1) cBTS3612-800 is generally configured with two BCKMs, one set as active and
the other set as standby. When the active BCKM is faulty, it will automatically
switch over to the standby BCKM. In this case, the active BCKM should be
replaced. If one BCKM alone is configured in the base station, the replacement
of BCKM will interrupt all services in this base station.
2)
BCKM 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 BCKM alarm and block a corresponding BTRM
Connect a portable computer with the local-end maintenance software with the
Ethernet interface of this BCKM and switch on Telnet to log on to the base station.
Then, view and record the fault type and software/hardware versions of BCKM.
For a BTRM which will interrupt services, execute the command of sector carrier
blocking or shut off its power.
& Note:
1. When a base station is configured with two BCKMs and the active/standby changeover is completed,
skip this step.
2. If the local-end login is unsuccessful, it is unnecessary to view the fault type of BCKM.
2)
Unplug the BCKM
Remove the GPS clock line and pull the BCKM out of the slot.
3)
Plug a new BCKM
Plug the new BCKM into a corresponding slot and install the GPS clock line. If only
one BCKM is configured, then you have to wait for the reinitialization of this site until it
succeeds.
