I have a Dell PE 1850 that has recently been re-purposed as a non-essential TFTP server. It is currently running Centos 5.4 with no GUI. It has redundant PSUs, however I only need one connected (available outlets are scarce in the full rack). Obviously this sets off the blinking orange warning LED on the front of the server and pressing the indicator button on the front does turn the LED blue, but it continues to blink.
What I want to know is, how do I make the server think that it only has 1 PSU and is not in an error state, keeping the warning LED solid unless something else fails? I don't want to remove the extra PSU, but I also don't want the LED to blink in the event of another hardware failure.
