Proliant ML150 G6 E5504 - Power problems

Hi all,

 

I've this server connected to an APC RS 1000 UPS (1000VA), it has been working for about 8 months with no issues. However, since a few weeks ago, every time there is a power outage, or power spike the server will simply turn off, just as if it isn't connected to an UPS. I thought this was an UPS problem so I changed the UPS, but the problem remains.

 

Here's the UPS own information:

When the power returns, the power suply led (the left one) will turn green, and the led on the power button will turn yellow (all the other leds are off). However, when I try to turn the server on it will not power on. The only remedy is to remove the power cord, wait a few seconds, and then reconnect again. After this if I push the power button it will turn on without issues.

 

Since I had only one power supply on this server, I've ordered a second one. The problem remains. Now I have to remove the two power cords for the server to recover! I've tried changing the power supply slot, using only the new power supply, without success.

 

I've checked the log in the BIOS and I get lots of events:

 

SEL Record ID: 0E28
SEL Record Type: 02 (System Event)
Event Timestamp: 2012.07.16 07:59:56
Generator ID: 0020
Event Message Format Ver: 04 (IPMI ver 1.5/2.0)
Event Sensor Type: 08 (Power Supply)
Event Sensor Number: 1B (RPS Redundancy)
Event DIr: Type: 0B
Event Data: 01 FF FF

 

The other events are "Power button events", the "Event Data" is always the same.

 

I don't think it matters, but I have Debian Squeeze running on this machine. It has four hard disks (2x2TB + 2x80GB). Also, I've followed the troubleshooting  procedures on the site and checked the leds inside the server. To no avail. 

 

Thanks for any help.
