IPMI ?

If you can't use IPMI, a friend of mine used a neat solution if you
have more than one computer running: connect a pair of serial ports
together using a null cable modem, so that you can monitor one
computer from the other. You can make a chain of connection so that
you can monitor more than 2 computers: basically you access the
console of the 'next' computer using a terminal emulator from the
'previous' computer, like a linked-list kind of arrangement.
