K400 troubles

Hello,

from time to time server shuts off with this messages on the front LCD:

DC OVERVOLTAGE
POWER SHUTDOWN

after that server turns on only after a few hours of idle. But the boot-process failed with next cycling messages on the LCD:

FLT 5002
FLT CBFC
FLT CBF1
FLT CBF0

till the end of time ;)

Only after memory board reinsertion or memory board and CPUs reinsertion/swaping server bots into normal condition.

The question is what I have to replace? System board, power monitor board, power supply or I have to burn this server?

Thank you.

Re: K400 troubles

The DC Overvoltage typically indicates a problem with the power supply. There is a chance there is a problem with the power monitor board as well, but less likely. The PM card is used throughout the K class series so if you have another server and some down-time to play with you can try the PM board to see if this helps or not.

The part numbers if you are curious are:

0957-0279 925 Watt Power Supply
A3641-60025 Power Monitor Board

Re: K400 troubles

I fully agree with Robert. I only want to add that if this problem will reoccur try unplugging server's power cord from its power supply, wait a little and try powering it on again. It should work as soon as all the electricity will drain out and all circuits will be reset completely

Re: K400 troubles

Problem with PS is not the main. The primary target is problem with FLT. Unfortunately this server - only one. And I can't play with boards. Replacement of the PS costs a lot of money, may be this replacement solves "DC Overvoltage" problem, but what about FLTs?

Thanks.

Re: K400 troubles

Thank you, Massimo. But I know the descriptions of this major codes. How can I determine which part I have to replace?
