I am not sure so sure. I think that Doug reminded me that I might have a switch/router UPS with no servers on it, and how am I supposed to monitor that then using my idea?

Quick fixes I can think of is 
	retain old usb/serial monitor system
	put a homeplug on it with the network cable plugged into a server and run some software on that server to monitor it.

> Arjen mentioned something similar before: if you want to see the status of a single UPS without involving a computer, there are UPSes with displays on the front. For instance: http://www.newegg.com/Product/Product.aspx?Item=N82E16842102070 (disclaimer: haven't tried this product.)
> Jon: if you want plug-and-play without a separate data cable, that is a different set of design criteria from James' original post. Powerline networking hasn't really caught on in mainstream computing, but HomePlug might be a good starting point.

I know it is a different set.

I know powerline networking has not caught on, but I think that is only because there was no need. I do take it exactly as a starting point, and I used that to avoid redesigning a new protocol and hardware.
