You need to go (as root)
yum install apcupsd
then try apcaccess. If nothing happens go
service apcupsd start
then try apcaccess again. It should be obvious if it's working. You might need
to edit /etc/apcupsd/apcupsd.conf. The comments make it fairly
self-explanatory. Make a backup copy first in case you manage to really foul
it up. Then go
service apcupsd restart
if you need to. Use chkconfig to get apcupsd auto startup next time you boot.
If you want to hang more PCs off the same UPS you can install apcupsd on those
too and get them to talk to the PC with the USB cable via the LAN. You'll
need to open the firewall port to do this.
