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.
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.
How is it possible?
What have I to do?
