The unique thing about gigabit is that there is data on all 4
pairs. Therefore, any pairs that have power need to go through
magnetics/transformers. If there is power on 2 pairs, then they
need the transformer/magnetic isolation. If there is power on 4
pairs, then all 4 need the transformer/magnetic treatment.

Gotcha, I'll check out the stock injectors. I was under the
impression all gigabit PoE was power on 4 pairs. Thanks.
The POE Injector that
comes with the unit will shed some light. It should say what
pins have +/- Tik and small UBNT Radios only have power on 2
pairs. Airfiber Radios have power on all 4 pairs.

only show two pairs having power. I'm trying to power
Mikrotik and Ubiquiti gear via 24v. Any resources that
someone can point me to?
