Overview
This article describes the input voltage supported as well as power required for the different airFiber models. Please verify each device's Data Sheet and Quick Start Guide before installing.
ATTENTION:All airFiber radios require 4-pair PoE power. Please check that the PoE source used delivers power over the 4-pairs. 2-pair PoE sources could create stability issues because of extremely high current over those 2 pairs. These are not recommended.

Additional Details
- Only AF-24, AF-24HD, AF-5/5U support -48V power source.
- Original airFiber 5X design only supported 24Vdc input. However units with MAC address 04:18:D6:E3:08:E9 or higher support input voltages +19Vdc to +53Vdc.
- Since airFiber 2X, 3X and 4X have been released after AF-5X, all AF-2X/3X/4X models support up to +53Vdc. But, since it consumes slightly higher power, it requires higher minimum voltage +23Vdc.
- The AF-11FX comes with a DC input connector, so it can be powered via PoE and/or direct DC cable using the DC input connector.
