I used to modify cheap switches to do passive PoE, which would work that way... I just had pins 4/5 & 7/8 on all the ports hard wired to the DC jack, so essentially all the ports were PoE in and out. It's pretty simple on 10/100 stuff... of course gigabit would make it a lot more complicated.
But I've never seen anything built to do that. On Tue, Dec 22, 2015 at 3:27 PM, Adam Moffett <dmmoff...@gmail.com> wrote: > Understood.
