ML570 power protection module error

This question is for an ML570 with quad 3Ghz CPU, redundant fan, redundant PSU, 4 x 36Gb HDD, 6 x 72Gb HDD, and extra 6 bay cage.

One of the processors sockets indicator lights is amber in color indicating a PPM error. (power protection module) What happens is that after the ML570 has been on for about 5 minutes, the server shuts down with a pop up message warning of overheating. We also tried shifting the processors around but it made no difference. If we disable Thermal Protection in the bios, the server does not shut down. But clearly this is not a good solution.

Has anyone encountered this problem before?

Hi,,

PPM is Processor Power Module.

You have to change the failed PPM. In the mean time you can pull out one processor and the failed PPM and then the server sould be running without overheating.

Thanks for that Akos. You wouldn't happen to have the part number for that would you?

Re: ML570 power protection module error

Thanks for your help guys. But I think the problem is more to do with the motherboard and HP tech support agree, so they are sending a replacement.
The problem is the PPM light was amber even when no CPU was in the slot, and would cause the Windows 2003 Server to shutdown due to a overheating indicator.
