[PLUG] power management question

[Michael Barnes]

I do know there are power strips with Ethernet connections that can control
individual outlets. Usually used for brute force resets of equipment, they
can be commanded remotely for whatever purpose. Available from Black Box,
etc. Might be able to find them at Fry's or appropriate online search.

HTH,
Michael
