UniFi APs and the usable PoE injecters.

This is based off a Reddit post that can be found HERE.

...that can take 24v Passive In

...that can take 48v Passive In

...that require 15W active PoE (AKA a PoE Switch)

...that require 30W active PoE+ (AKA a PoE+ Switch)

...that can run on 30W active PoE+, or 48V Passive

...that require 60W active PoE++ (AKA a PoE++ Switch)

Power Injectors

General naming convention: POE-Voltage-Wattage-Gigabit?-White?

POE-24-30W-G-WH = A white, 24V, 1.2A (30W) Gigabit model

POE-48-24W = A black, 48V, .5V (24W) 100 Mbps model

There are a few exceptions. Ubiquiti's PoE injectors are like Whose Line is it Anyway. The rules are made up, and the names don't matter. For example the following have Gigabit ports, but no G in their model name:

So... G means gigabit, except when it doesn't.
