If you have a Smart UPS, you can configure the kill power grace period,
and you might want to set it to 3 minutes. If you have a dumb UPS, there
is no grace period and you should not use this procedure. If you have a
Back-UPS CS or ES, these UPSes generally have a fixed grace period of 2
minutes, which is probably sufficient.
Power Down During Shutdown
Our philosophy is to shutdown a computer but not to power it down itself
(as opposed to having the UPS cut the power as described above). That is
we prefer to idle a computer but leave it running. This has the advantage
that in a power fail situation, if the killpower function described above does
not work, the computer will continue to draw down the batteries and the
UPS will hopefully shutoff before the power is restore thus permitting an
automatic reboot.
Nevertheless some people prefer to do a full power down. To do so,
you might want to get a copy of PsShutdown, which does have a power
down option. You can find it and a lot more useful software at:
http://www.sysinternals.com/ntw2k/freeware/pstools.shtml. to use their
shutdown program rather than the apcupsd supplied version, you simply
edit:
c:\apcupsd\etc\apcupsd\apccontrol
with any text editor and change our calls to shutdown to psshutdown.
