I have an HP ProLiant DL580 G5 whose power button does not work. The server runs, but the button does nothing.
Unfortunately, the server has turned off, and I guess my "boot on power" settings did not stay. I also know nothing about ILO, but maybe it's an option?
How do I turn on this server without a working power button?
In the future, know that the power button is simply a momentary contact switch. This means there are two wires and jumping them together for a split second with anything will energize (or deenergize, if held for a few seconds) the host.
We found that the connector from the front panel was disconnected from the motherboard. Reconnecting fixed the issue.
