I think you want the impossible (to quote Luke Skywalker :-)

If it won't respond to the network and it's sleeping, then the OS level is out.
If it doesn't have a separate management interface or ASR the BIOS can't do it.
If you can't control the power cord remotely then a hard reset it out.

What's left? Carrier pigeons trained to peck the right buttons, or
minions with cell phones and keys to the server room :-)
