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.
