I also use an RS/XS 1500 + extra battery to keep several PCs and other
networking odds and ends up. With all this junk running it holds up
for over 1 hour and if I'm away and have monitors off and shutdown one
of the three PCs it lasts over 2 hous. This has been a very good UPS
for a very small network.

I monitor it from a RHEL5 box and don't bother with extra packages ...
just use HAL directly and have a small script to notify me of events
... I deal with shutdowns as needed rather than relying on the UPS as
