power controller

[Jason Jorgensen <jjorgensen@mediaone.net>]

Anyone know of a remote power controller. I am looking for something
that can physically remove power from a computer and then reapply
(trained monkeys and janitors aside). We have a power controller now
that has a serial interface but it only controls 8 computers with a
individual relay for each computer. We would like something that could
control power for 16 or 32 machines in racks and that has an ethernet
interface.

Thanks
