The system might be set to use a serial console.  Try connecting a null
modem cable between the O2 and another machine (PC, Mac, Linux, whatever
you have handy) running a terminal emulator and see what that says.  You
may find an error message about failed graphics causing it to fall back
to a serial console or maybe that it's configured for one regardless.

If you haven't already, check out both http://forums.nekochan.net/ and
the wiki there for more info about diagnosing and fixing SGI systems.
Those forums are much more active than this newsgroup.  I have several
SGIs but I don't have any hands-on experience with an O2.  So,
unfortunately, I can't offer any more advice than that.

Good luck!
