I have configured several brands of IPMI controllers. Usually there
is a menu on the CMOS setup for configuring an IP address (or dhcp)
and there may be menu options for setting user names and passwords.
Otherwise, there may be a bootable disk image for initial setup. In
any case, unless the IPMI was set up in advance, you probably wouldn't
be able to use it to power-cycle the machine.

Our experience is that IPMIs are not that reliable. They sometimes hang 
when the main OS hangs, and sometimes forget their setup. They usually 
come with motherboards with more than one ethernet port, and the 
instructions are rarely clear about which port connects to the IPMI, so 
you have to experiment.   I'd rather have a "whack-on-lan".
