Re:13W could be dangerous... (Score 1)

I was present at one of the first trials of this technology, before the bugs were worked out.

We installed new cubicals and had them wired for both ethernet and electricity. The electrician made a mistake and wired the electricity to the ethernet terminals - 220 volts.

Fortunately it burned out the ethernet cards in the local and server computers before it did any more damage.

(That may be why the reduced it to 13V ;-)
