apparently, not have a ups on your gnatbox invalidates the warantee.. which
may be worth some thought.

Subject: [gb-users] Changing gb-1000 startup behaviour after power cut


Does anyone know if I can ensure that if our electricy supply goes down and
back up again, the gb-1000 *doesn't* come back up, either using the gb-1000
user interface or by configuring a low level model APC UPS?

If you're interested, here's the background:

Every so often we have scheduled power outages, eg, annual testing of the
building's power supply.  We have another potential one this weekend.

Our gb-100 doesn't have a UPS attached.  In the past, I've either shut it
down and turned it off or just let it go down and back up with the power.

This weekend, there is only a low probablility of a power outage, so I'm not
inclined to turn off the gb-1000.  However, if there is a power cut, the
gb-1000 comes back online and tries to relay mail (we use the mail proxy
service) to an internal mail server.  If the internal mail server hasn't
come back online after a graceful UPS shutdown, the gb-1000 tends to bounce
incoming mail back to the sender, ie, it doesn't do store and forward.

One way around this is to ensure that our mail server *does* come back
online after a UPS shutdown and I'm working on this.  The other option is to
prevent the gb-1000 coming back online after a power interruption.
