So, there are people here powering AF24's with 54-55 (float)
voltage without issues? Just trying to rule this out.

No, 54-55 is a good float voltage for lead acid 48 VDC batteries.
The voltage itself has nothing to do with the data.
Too much current could affect it, but in my testing, the chip
with the magnetics will unsolder itself before it stops
passing data.

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

The stock AF24 power supply is 50v, if I remember correctly.

Isn't AF24 only 48v?

OK, there are some half watt resistors in that
area. When running at 55 volts limiting current
for the LEDs they do get hot. Their temp depends
on system voltage. I had hard to make the LEDs
usable for a range of 6-60 volts without some
tradeoff.
As long as the large chip isn’t getting hot you
are OK.

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

Or is it the area right by the LED's?

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 noticed that the ethernet link
on the AF24 was dropping (and coming back
very quickly). I'm not sure if it's related
or not.
