Just built a server using a P4304SC2SHDR server system. This system features 2 x 460W Hot Swap power supplies.
One of the power supplies is running its rear fan at very high speed from power up while the other PSU is nearly silent. I have tried with 2 x PSU and then one each in turn in both bays. When the quiet PSU is powered up the PSU LED. stays solid green. When the noisy PSU is powered up the PSU LED stays flashing green at about 2Hz which according to the manual is "Power Supply FW Updating" but it just stays running noisy for hours.
Quiet PSU on its own Runs Quiet
Noisy PSU on its own Runs Noisy
Both PSUs Noisy PSU runs noisy blowing a lot of air while quiet PSU runs quiet.
Both PSUs Swapped in PSU sockets gets same result.
I know there is an FRUSDR bug on this board but I have run the remedy and actual FRUSDR many times.
Apologies for bad pictures.
Is the noisy PSU fixable, can it be changed from it's FW updating state or do I need to RMA it?
I'm guessing the FRUSDR error and Intel Deployment Error are note related but I'll mention them anyway.
OK this as RMA'ed by tech support. Must not be fixable on site.
