HP 9000 K580 server problem.

Hi,

I got a problem with K580 server, it displays " LOW DC VOLTAGE" error message in LCD panel and shutdown. I can't restart the server unless until i pull-out AC input power cable from the server for about 1-2 minutes. Once i put back the power cable server boots up normal. but then the same problem repeats after 2-3 weeks time.
Any clues on this please ? thanks in advance.

I'm assuming this machine is on a UPS. It would appear that in that case the battery is having troubles.

You should get it checked and probably run the system with the UPS in bypass mode until service is complete.

This is definitely a power issue and that is what should be investigated first. You may need a hardware call to get this corrected.

Hi Steven,

Thnaks for the reply.

This server is connected to central UPS. There are few other systems also connected to same UPS and all the other systems are working without any such problem. I also checked incoming voltage 230VAC and is ok.

BTW, from the server to UPS there is no UPS monitoring cable connected, but ups_mond is enabled. do you think this can casue this problem to happen?

Re: HP 9000 K580 server problem.

You probably have a marginal power supply in your K-box although you could have a slightly over-sensitive Power Monitor Card. (The PMC is located next to the Processor 0 card.) Your condition could be aggravated by higher than optimal ambient temperatures. How good is your room's HVAC system? The good news is that you should be able to find both of these parts at dirt-cheap prices on the used equipment market.
If it ain't broke, I can fix that.

Sometimes just reseating the power monitor board, power supply, and (believe it or not) memory can resolve an issue like this
