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