PoE Injectors Forums WiFi Access Points Unifi- a or b? Reply To: Unifi- a or b?



Hello –

It depends on the Unifi model. If the model uses 24v PoE, then you need mode B. For other Unifi models, mode A or B will work.

Almost all of our injectors support mode B. The only exception is the Gigabit 4 port injector. It’s mode A only.
