That would certainly be enough to make the light blink amber, as it is a hardware error that would require your attention.  Since it is much less likely for a processor to fail, I would probably assume the motherboard at this point, but it is possible that the voltage regulators on the processor itself are not working properly.
My customer has a T110 Poweredge tower running Centos linux I set it up in August 2010. There were a number of issues with it at the time and eventually dell replaced the power supply under warranty Since then it has been running without a problem until this week. The warranty has now expired. Three times in the last few days the server has restarted itself during the night, usually interrupting the backup. Centos logs are normal up to the point of the restart with no clues as to the reason. Then the restart is logged and runs to completion, the server is then completely operational on the network and accessible. Once is one of those things, three times is something else. The system health led on the front panel is flashing, but the centos hardware diagnostics do not show any issues. I suspect another power supply problem and have been looking for a replacement 305W psu. However it appears there are two possibilities R480P and N238P - the dell site does not tell me which psu it has for 5HYXS4J and a replacement psu is not listed as a dell spare part. Two questions, would random restarts indicate a psu problem and second, does it have the R480P or N238P and are they interchangeable? Regards, Peter Lawrie
