LPU5 Alarm

LPU5 Alarm

(OP)
Hi,
There is alarm on LPU5 connected in magazine 0, both Green and Red light are on, display code 3320. LPU5 connected in magazine 1 is OK, display shows 104. ALLOP; shows no major alarms, LSFTI:LIM=1,FULL=YES; shows DSU boards are OK, I have replaced PLU5,LSU, DSU in magazine 0 and DSU in magazine 2 but it doesn't work.
Please help to remove this alarm....

RE: LPU5 Alarm

The display shows there is no connection to DSU in Mag 3.
What does DCSSP; show?

(OP)
thanks for replay,
DCSSP;
DCSSP:LIM=1;
GIVES COMMAND UNKNOWN
Please note the system is just one LIM.

RE: LPU5 Alarm

Hello,
If the pabx has only 2 cabinets, code 3320 is correct, the second LPU5 waits for loading if appropriately configured. If the command answers you unknow, there is probably no DCSP and DCSH program loaded.

RE: LPU5 Alarm

can get this alarm when there's an old IPU board or 2nd NIU board causing the system in trying to load from it instead of the proper NIU" with your build disc in. pull all other IPU boards out and button the system for it to load correctly
