Looking for an UPS for ReadyNAS Duo v2

You're right, I was talking about WoL over Ethernet, which requires the UPS to have a Ethernet port (not for RJ45 port protection but for sending WoL signals). Does it only exist on cheap UPS?

I have never seen a UPS with this feature at any price point. It is a cool idea, though I think it would need some configuration on the UPS side to have it work properly. BTW, don't confuse RJ45 with ethernet. Some UPS do use RJ45, but they are not using ethernet. RJ45 is just a connector.

...What do you mean by drain?

Drain->run down the battery to the point where the NAS is told to shut down. Almost all of my power failures are very short (a few seconds to a few minutes). My UPS will power the NAS for a half hour anyway (the UPS status says about an hour at the moment).

Yours are obviously much longer.

The way this is normally handled is that the UPS is configured to hold back power until it is reasonably charged up. The protected devices (NAS in this case) are expected to have bios settings that allow them to automatically boot when power is restored. The ReadyNAS doesn't let you adjust the bios settings to do that.
