Yep! Power over Ethernet + Gigabit cable = instant fried expensive
Gigabit device!

Which brings the question.. do Gigabit devices have hardware sensors
that sense the Power over Ethernet voltages, and if they are present,
cut out the Gigabit functionality and isolate the cables?

Or maybe they'd just have a DC blocking capacitor in the middle, and
suffer the extra line noise from having big 45VDC on the lines.

(Hmm. It's a bit off topic I guess. Sorry!)
