I found that my network shelf (Common Equipment) Group 0 Shelf 0 was down this morning.

I was able to re-enable everything and it came back up. My Core 0 (CP4) had AC NET Loop 12 on the LCD display. I cannot find this in the MERL. What does this mean. At first I thought it ment AC power error. We are using DC power from a powe rectifier... anyone know what this error means?

My core 0 column also had a red alarm at the top (top led light). Everything is enabled and all the fans are running... where do I check for errors on this?

Is everything ok with your DC power plant?

I get those DCON alarms when we have a power failure on the MFA150s / MPR25s.

Is there are cable from one of the DB9 connectors on the system monitor (I forget which one) to the rectifiers? What type of rectifiers are they?

Can dial out on PRI

It is really old... dating back from when we had an old 61 (way back). It is an external unit in a seperate room. Has Northern Telecom on it.

Hi!
I also found one problem in my switch last week my key codes wee upgraded and after that system ask for restart. when exchange was restarted after that core shelf became available after one minute but Major alarm was ON on both columns and incoming ring problem on analog extensions. all extension did not receive ring when some one call on them. after midroutine ended one message was reveived from system monitor about
pwr000 pwsp 00 1 2
pwr000 pwsp 00 2 2
pwr000 pwsp 00 3 2
pwr000 pwsp 01 1 2
pwr000 pwsp 01 2 2
pwr000 pwsp 01 3 2

SRPT183 xsm: Alarm signal cleared.

any suggestion from your side.

after syste monitor message ring problem was solved automatically.
same was also happend one time before when keycodes were loaded for call pilot.
