In addition to Wake-On-Lan mentioned by Shimi, there are also: 1. Boot on AC power - i.e. if the AC power comes back then start reboot. That's a BIOS setting.Which assumes a power loss after the automatic shutdown. According to Murphy law, and to my experience, power tends to return 1 minute before the battery gets completely drained, just for me to wonder "why oh why did I shut down my whole server room, it would have survived". Of course that if I wouldn't have shut down everything, the outage would be 1 minute longer. :)
That's exactly my experience. Murphy's law is more reliable than gravity...
So still need WoL :) (to be initiated by the machine sampling for the UPS remaining battery after the battery managed to re-charge for additional few minutes of backup power - enough for a second power up and shutdown of everything assuming a second outage...)
We'll try to go for a solution like this. Thanks to both Amos and Shimi for the suggestions.
