Yeah, it seems to be just the area around the LED. The connector is not very
hot at all.

We just installed our first GIGE-POE-APC which is powering an AF24, and
noticed that it gets VERY hot. So hot that it almost instantly burns your
finger when you touch the green molding. For folks that have these
installed, is this normal?
It's ran fine for a few days, but this morning we we

design with pre-warming resistors to reduce cold inrush current, so the bulbs
would glow dimly when “off”. The world is better with LEDs.

Stock is 50V. I'm running them directly off a Traco TSP (~54V). I wonder if
this is why the ethernet keeps dropping.

On the other hand, I don’t think you need to design for as low as 6V.

They don’t throw off much heat, the resistor is rated at 0.5 watt and it has
never failed.

I did mention this here when I was bench testing powering an AF24. My Traco was
floating at 55 volts. The radio ran fine.
It's not that it's powering the radio and getting hot. If you feed the card
with 50+ volts, the LED still gets
No, 54-55 is a good float voltage for lead acid 48 VDC batteries.

No, but it does give off some light at 6 volts (you have to be in a dark room
to see it).
