I was confused at first too. It looks like Chuck may have got the 4/5 &
7/8 pair jumpers backwards, but fixed it on the label and simply blacked
out the print on the board. The paper label on the back of the card is
correct. I've used several in the past month on 2-pair and 4-pair
powered radios without issue.

Chuck (or all),
I've got a question on the GIGE-POE-APC (the concept of which, I
love). I've got two pictures attached, appropriately labeled, of the
jumper configurations. But, I'm confused. When I look at the drawing
on the back, it says jumper to the left for positive and to the right
for negative. Indeed, when I use an ohm meter, the left pin is 0 ohms
to the positive lead on the phoenix connector and likewise, the right
pin is 0 ohms to the neg on the phoenix connector.
But, when I plug in a UBNT with the jumpers configured so 4/5 is pos
and 7/8 is neg (as in the "didn't work..." image), my power supply
goes into short circuit protection briefly and the GIGE-POE-APC smokes
(once it lets the smoke out, the power supply is normal again). So I
have to set the jumpers so 7/8 is pos and 4/5 is neg (as in the "works
with ubnt" image). But I also see that the 4/5 and 7/8 labels seemed
to be "sharpied" over; is this because those labels are swapped and
the bottom pins are actually 4/5 (which would make sense)?
Thanks!
