Powerd in Linux

[Oommen Thomas <oommen@xxxxxxxxxxxxx>]

Anybody out there has used 'powerd' for autoshutdown of a Linux server
when UPS runs out of battery.

Iam using RHL5.1/5.2

The inittab has the following

----
# When our UPS tells us power has failed, assume we have a few minutes
# of power left.  Schedule a shutdown for 2 minutes from now.
# This does, of course, assume you have powerd installed and your
# UPS connected and working correctly.
pf::powerfail:/sbin/shutdown -f -h +2 "Power Failure; System Shutting
Down"

# If power was restored before the shutdown kicked in, cancel it.
pr:12345:powerokwait:/sbin/shutdown -c "Power Restored; Shutdown Canc
----


Does this mean that if powerd is installed and if we have a UPS (which has
this alarm provision) connected to the system's serial port by a cable,
the signalling by the UPS will shutdown the server automatically?

Any other addl setting is required for this?

TIA.
