Server System SR2625URLXR Pwr Unit Status error

[idata]

Hello, my Server System SR2625URLXR has worked about an year without any errors, but now it fails every week with error: "Pwr Unit Status reports the power unit has suffered a failure." After the fail server either restarts automatically or shuts down with BIOS beeps. Server is connected to two different UPS's, and it's power is stable.

In the BMC log I see follow messages:

My question: Is this motherboard on power distribution board error?

[CToed]

Hi,

please disconnect all UPS and watch the system.

Such issue often cause by UPS.

The second issue is a problem of mainboard or/and PCIe cards.

Which PCIe Cards are inserted?

[David_A_Intel]

The issue could be related to the power supply or the power distribution board. I noticed, at least on the text you posted, the errors are related to PS1. I did not notice any errors for PS2.

If possible, try to swap around the power supplies to see if the issue follows the power supply or the slot it goes into. You may want to disable PCI AER Support in BIOS > Server Management to clear possible PCIe errors.

As usual, make sure your system is running at the latest https://downloadcenter.intel.com/download/24808/Intel-Server-Board-S5520UR-Firmware-Update-Package-for-EFI BIOS release 64.
