I don't know if also in your case but in mine, once that happens, the connection doesn't get back, what means, from then on, the ups stays unmonitored. Another problem I bumped into (this is my first experience with a UPS unit) is before purchasing this device I'd assumed that to wake up the machine once the AC was back would suffice activating the "auto power on when AC is plugged" BIOS option. Wrong. :-) Then I tried a router with dd-wrt software that comes with a wol daemon, it didn't work either. Routing a wol packet from the internet (adding static arp entries in the router as they teach in some forums) wasn't either possible. What makes me conclude: if you can't rely on the machine will be shut down properly and it's so difficult (automatically or remotely), to get the machine powered back, what in the Hell a UPS is useful for?
