HP ProLiant DL380 G5 Server: is the power supply really broken?

[Frenky-77]

I have a HP ProLiant DL380 G5 Server with a redundant power supply.

After more than one year I noticed the "External health LED (power supply)" was amber: "Power redundancy failure." The power supply on bay n. 1 was degraded as I could seen on the front panel, from the bios startup and from the back of the server too.

Power supply failure

I rapidly ordered a spare part but, after it arrived, I run to replace the power supply with the new one and I found that the power supply was regularly working.

Power supply ok

How is it possible?

What have I to do?

Hello, 

Was it loose connection on Power cable? Did you check that before you order a replacement?

Kind Regards

Yes, I checked the power cable connection very accurately and the error led
was still on.

I had 2 servers where the second power supply went broken and the server shuts down.
I had to replace both power supplies.
At the office I tested the powersupplies: 1 was complete broken, servers doesn't start. 1 power supply was 'half' broken: fans start spinning, power-button lights amber, but the server can't start with this half -broken powersupply.

I read all the posts about power supply issues but actually no one seems to
be helpful.



Now the power supply seems to be good and I'm waiting for a new problem.



Just a question: can I see with the ILO if the power supply stops working or
how many times it happens?
