I have an IBM x3650 unit with redundant power supplies. The two units are plugged in. If the left unit is unplugged, the server shuts down meaning power does not fail over to the 2nd unit. On a closer look, I noticed that the DC light on the 2nd unit is off. Does this mean that the unit is faulty.
I looked up the Light Path Diagnostics but did not find any pertinent info.
