I never got a 'round tuit: we have pretty reliable power and all
important stuff is on journaled raids.
As I recall you can send powerfail either to a monitoring daemon
(apcupsd?) or as snmp trap; with recent firmware you can also group
upses to send the signal only when both of them lose power (with 2-psu
machines connected to 2 upses on independent circuits). However, this is
the opposite of what you want.
Their networked power strip lets you turn individual outlets on and off
-- dunno if you can do it via snmp, though. I'm sure you can wrap
telnet/expect or http/curl script into a plugin if it comes to that.
