I hear you, but this box has three redundant power supplies, all load
balanced.  IOW, I've had it running on 2 when I had to replace one, and I'm
told that it'd run on only one if it had to.

The lights are all green on the backs of the power supplies.  I don't know
how else to check if they're all working.  The last time one failed, the
green light went out.

This motherboard only seems to hve the one ide channel, I can't find a
connector for a second.  I've attached the DVD to the slave connector on the
primary channel (/dev/hdb) and I'm running mondoarchive again.  I'll keep
y'all posted.
