There is heat given off at all voltages.  And that particular unit might have a 
fault in the resistor.  Solder bridge or wrong resistor.  Have not seen that 
before but could happen.

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.
