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?

Subject: [AFMUG] GIGE-POE-APC Hot?
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.
