A bit of advice: If this is an unattended system, give some thought to how
you will boot the server back up if the outage is longer than two minutes
but shorter than six hours.  Most UPS installations have *some* kind of
race condition issue if power comes back after the servers have begun a
shutdown, but in your case it's an unusually long window.
