Re: UPS Advice

Ideally the load should be able to tell the UPS once the
shut-down is complete so that it can switch off its output.
In a perfect world I would like to be able to configure the
UPS not to re-power the load until the battery was charged
again.  This isn't rack mount and 700VA should about cover
it.  Does anyone have UPS recommendations?

I'll echo the APC recommendations.  I have 3 of the SMART-UPS family (the
older serial-only models).  I use NUT (pkgsrc/sysutils/ups-nut) with them
but there is also apcupsd.  They do:

 notify when switching to battery/mains
 shutdown after configurable delay
 startup after configurable % charge

I use apcupsd in network master mode which, as there is a Windows port too, means I can control a whole heterogenous server farm connected to a single UPS from a NetBSD machine.
