Although, if you have a server running from a UPS (without the mains
feed, so your on batteries), and the UPS drops to say 20% remaining, it
control shuts down your server.
So the questions are:
- What will make the UPS start to supply power again?
- Does it wait till it is fully recharged
- Does it just wait till it has a mains supply again (what happens
if the power supply goes again before the machine has got back into
windows and can't be control shut-down?)
- How do you turn the server back on, because it was shutdown cleanly
the "restore last power state" in the BIOS won't work, although maybe
"always on" might come up trumps.
- How do you get multiple servers back up if running from one UPS?
You need need to drive a switch from the UPS too, and then have a master
machine which did WoL maybe to the other servers?
Cheers,
Matt

Thanks Ben. I guess I'm going to need to schedule some down time on
these servers and refresh my memory about what can be done with the
bios.

Im not sure how to 'turn it on' other than set it in the bios to reboot
upon power loss or last state. APC has an option to cut power with their
web mgmt card that I saw long ago allowing the remote user to 'cycle'
power using the webcard on the apc.

This may sound like a silly question, but I've only ever used APC and
PowerChute Basic with my servers, which is great at shutting down
servers during power outages and what not, but now I need a solution
that will turn the server back on. I understand that my Dell servers
have settings in their bios that can be set to start the server in the
event that power is reapplied (PE2900), but I've a pair of older HP
Proliants (An old ML310 and a ML330) that I don't think have this
feature. Is there something in the Full version of PowerChute that
would turn a server back on when the power is reapplied?
