Possible CPU Board failure - need to review

Hello guys,

So there is an HP Integrity RX6600 server, which simply cannot be turned on. When user power-on the chassis, the server goes into Power-off mode immediately (afer 5 seconds)

After reviewing logs (MP logs), we found that the chassis hasn’t any chance to do basic checks and stop at beginning so it has to be a critical section of the server like (CPU Board or CPU modules)

System Processor Status:

   Monarch Processor: 1

   Processor Module 0: Installed and NOT CONFIGURED 
   Processor Module 1: Installed and Configured

 

So basically we've ordered second handed items like:  Power supply module, CPU board + CPU modules for replacement on the server.

Power Supply modules are OK, we confirm that. However we’re not sure about CPU Board. Because as soon as we replace the old CPU Board with new CPU Board that we purchased there will be no AC power indicator on Power supply not or the Power button !!

When we replace it back with faulty CPU Board, AC power will back on both Power supply and Power button.

 We even tried to only replace 1 CPU module (new one) on the old CPU Board (Processor Module 0: Installed and NOT CONFIGURED), but again same problem (the server power-on and after 5 seconds it will be turned off).

Could you please guide us about this problem. is there anything else i can do for troubleshooting ? have you faced this problem before ?

Thanks.

Hello guys, 

Based on the tests we did, could we assume that new CPU Board is faulty ?

Re: Possible CPU Board failure - need to review

I've some update, first the AC power back on with new CPU board. But we face pretty much same problem we had with old cpu board. Which means the CPU on Slot0 doesnt detected. We already tested it with 4 CPUs but same result. In one testcase we actually removed CPU from Slot0 and let system to boot up with installed CPU on Slot1(which is detected normally) but we receive FRU missing device - Processor 0 error. MP->CM->SS also reports that:
Pocessor 0 is installed but not configured
Processor 1 is installed and configured

Which i found it very abnormal as far as there is no cpu at that slot.

Really confused right now. Can anybody help me.
