What does "PoE interface (8) 60W PoE++ (Pair A 1, 2+; 3, 6-) (Pair B 4, 5+; 7, 8-)" mean?
Question
Looking at the new USW-Flex-2.5G-8-PoE switch and don't understand what the following means.
From the specs:
|| || |PoE interface|(8) 60W PoE++ (Pair A 1, 2+; 3, 6-) (Pair B 4, 5+; 7, 8-)|
|| || |Power method|(1) AC power adapter, 54V DC, 3.9A (Not included) (1) PoE+++ (PairA 1, 2+; 3, 6-)(PairB 4, 5+; 7, 8-)|
I understand that an AC power supply is not included.

If I understand what I am looking at...
Why would they spell it out like that in the UI device specs instead of just saying it meets the IEEE 802.3af standard PoE pinout?
