That's precisely it.  Some (all?) pmacs with server mode don't
automatically turn on after an intentional shutdown, only after power
is lost.  So the idea is to have the UPS signal the computer to halt,
and then have the UPS cut power once it's safe.  Later the UPS switches
power back on and the computer will automatically boot.
