Excessive Power Supply Failures

Hello All,

Looking for a little help here. We have a DL380 G5 that has had multiple power supply failures. The server is connected to a APC SUA1500RM2U UPS.

We have had failures/replacements in the below:

Bay 1 - 4
Bay 2 - 2 (1 Currently)

We have replaced the power supply backplane once. We've had the server in production since August 2008. Does anyone have any suggestions?

My only thought would to be to have HP bring out Qty 2 Power Supplies and Qty 1 Power Supply backplane to replace the entire assembly.

I would be highly suspicious of that UPS.

As an aside, the only time I have seen high PSU failure rates was due to zinc "hairs" coming away from old suspended floor tiles with galvanised bases and being blown up (through the air conditioning outlets), but obviously that affected all machines in the datacentre.

Thanks. I'll try calling APC to see what they say. We shouldn't see this kind of problem.
