Cabinet Alarm

[jmcooney]

After an inadvertent power down (contractor turned power off instead of bypass on generator), we still have a cabinet alarm on an Option 61 AC system (it is a CS1000M, but still looks like the good old 61, if you need perspective on the platform).

All the AC power packs and ring gens look normal to me -- not to mention the system appears to be working fine since the incident more than 36 hours ago.

- any ideas what else we need to check?
- is it possible to get a system message that indicates the source of the alarm
- is it possible to manually clear the alarm (and if the issue is already cleared, the system will leave the LED off, but if the issue still exists, it will light again) -- this is possible on an NEC 2400 IPX and is quite handy?

Please let me know. Thanks.

As John insinuated it could be a either a power problem or a faulty system monitor board. I would also go to ld 22 and print out your history file look for anything strange in the Sysload/INI sequence. Also check the midnight routines.

also make sure your fans are working below

It's only dialtone-VZ

Check the UPS connection to the power monitor card. Some are set to monitor UPS health with a contact closure.

Unfortunately, the stat of the xsm in LD 37 yielded nothing, but I did see some XSM messages in the history I was able to capture after I was informed of the power outage (I extracted only a couple of these lines as they were all the same). Not sure if this provides any additional hint as to the problem.

XSMC 00 0 0 is a good thing.
But not seeing anything for other cabinets.
It should look something like this:
PWR000 XSMC 00 0 0

PWR000 XSMC 01 0 0

PWR000 XSMC 02 0 0

PWR000 XSMC 03 0 0

PWR000 XSMC 04 0 0

PWR002 PWSP 05 2 1

PWR000 XSMC 06 0 0

PWR000 XSMC 07 0 0

If you notice it shows here a pwr002 pwsp 05 2 1
That is because on pedestal 5 I have module 2 powered down.

You should be getting a report for each pedestal. Check to make sure your line cords string from power monitor to power monitor. If they are there you may have a bad system monitor in pedestal 0.

 

[jmcooney]

Actually we only have one pedestal [one pedestal stacked 4 high --- 2 CPU/Net and 2 IPE).

 

[TAnselm]

Then I would say that the system monitor board is bad. I didn't see anything in your short printout to indicate a problem. To replace the system monitor board make sure you first disable the system monitor port in ld 37.
If you don't know what the port number is simply go to ld 37 and do a STAT on TTY. It's usually TTY 0 but not always.
Sequence of events should be:

got to ld 37
REQ DIS TTY X
remove cables from system monitor.
remove system monitor
Check dipswitch setting on new system monitor
install new system monitor
replace cables to system monitor
REQ ENL TTY X
REQ STAT XSM

 

[jmcooney]

If it was a bad system monitor board, would (could) it still be showing ENBL?

TTY 0 : ENBL DES: systemmonitor

 

[TAnselm]

Yes it would / could

 

[TAnselm]

If you want you could try disabling it, reseating it and re-enabling it. I've seen that work before, but when that happens it's usually just a matter of time before it goes altogether. Your Fans are running aren't they? I didn't see a reply from you on that question.

 

[jmcooney]

I think so, but actually I am at a remote site and am trying to see if I can direct a local person to check a couple of things.

We have a maintenance contract so when it appeared that we might have to do some physical troubleshooting, we called the vendor to come in and address.

Actually, I am not even sure I know which card is the sysmon card (from where you indicated "disabling it, reseating it and re-enabling it"). Is it a small card on the back of the pedestal?
