[plug] ups for home

[Andrew Elwell]

I have a low power ion server that acts as my NAS and does misc house
stuff (linux) and a windows desktop.

I have a smart-UPS 420 that powers router, poe switch (and therefore
voip phone and some arduino stuff), nas and pc.
Running apcupsd on the nas (serial connection) and the windows client
(lan) means that the windows pc does a clean shutdown soon after
powerfail (5 mins I think) and I get about 30 mins remaining on the
rest of the kit.

if the windows box is off runtime's about 1h
