Re: UPS signal status

(Sorry for the delay.  Friday appears to be the day the alligators come 
out and I am up to my keester in them.....)

Not as I understand it.  The QUPSDLYTIM is for how long you want the i 
to remain on battery before shutting itself down.  My understand is that 
if the power fails and IF the batteries report in as weak, the i takes 
matters into its own hands and shuts down pronto, regardless of the 
QUPSDLYTIM setting.

They oftentimes take down our "new and improved" Windows 2003 servers (especially the one running MS-Exchange), but our i5's never hiccup.  We did have power down long enough a few weekends ago (we're basically a 10 x 5 business) to drain the UPS, and that shut 'em down flat.  But blips don't.
