Full description
Apcupsd can be used for power mangement and controlling most of
APC's UPS models on Unix and Windows machines. Apcupsd works with
most of APC's Smart-UPS models as well as most simple signalling
models such a Back-UPS, and BackUPS-Office. During a power failure,
apcupsd will inform the users about the power failure and that a
shutdown may occur. If power is not restored, a system shutdown
will follow when the battery is exhausted, a timeout (seconds)
expires, or runtime expires based on internal APC calculations
determined by power consumption rates.
