If the APC software is a shell script, or a C program to which they give the
source, then you can modify that to talk to the RedHat box and tell it to
shut down (numerous ways of doing that) just before it initiates its own
shutdown. If you don't have the source, another option would be to do
the monitoring on the RedHat box (where of course you will have the source
of the monitoring tool - look for the UPS Howto) and have it tell the SCO
box to shut down.
