[AFMUG] Packetflux powerinjector input rating?

[Seth Mattinen]

If the description for the Packetflux powerinjector plus sync gigabit 
says "2A per per port maximum power when using all 4 pair powering 
schemes.  (96 watts at 48 V)", is the input maximum 8A on a single input 
or does it have to be split 4A across inputs A and B?
