UPS to Mac USB connection and hub
Authored by: randydarden on Oct 11, '05 07:34:46AM

One tip (I think I read this here): if you have your UPS connected to your Mac via a powered USB hub, make sure that the USB hub is plugged into one of the battery backup sockets on the UPS. Otherwise, when the power fails, the hub will lose power and the UPS won't be able to shut your computer down.

Absolutely, I've seen this exact scenario more than once. Good way to screw yourself if you're not paying attention.

Of course, if Apple would join the 21st century and put more than 2 USB ports on the back of a computer, we wouldn't have to dangle everything off of hubs.

I was under the impression that most powered hubs, if the power is disconnected, simply revert to being unpowered ones. Certainly both of mine do. Since the UPS presumably isn't drawing any power from the USB tree, it ought to carry on working fine.

Plugging the USB hub into the UPS is vital if you use USB-powered drives, of course.
