ISP Wireless - Guide to Device PoE Compatibility

This table will help with selecting the correct PoE for Ubiquiti's ISP Wireless devices. Most radios come with the required PoE adapter (notable airMAX exceptions include Bullet variants & NanoStation 5AC Loco).

Notes: When planning to use the PoE Passthrough feature found on the NanoStation M2/M5, NanoStation 5AC or NanoBeam 5AC-GEN2, it will be necessary to add the wattage of both devices. Please see the PoE Adapters Datasheet for more information on all our PoE adapters.

PoE Compatibility Table

The table below displays the compatible PoE adapters listed downward in the first column, and the ISP Wireless devices, listed in the first row. Check marks show which device is compatible with each PoE adapter.

Input and Power Table


Shown below is a table of the listed Input voltage & power ranges for various airFiber devices.



Input Voltage

Power Required

AF-5X Lower than 04:18:D6:E3:08:E9 +19Vdc to +25Vdc Up to 15 Watts
AF-5X 04:18:D6:E3:08:E9 or higher +19Vdc to +54Vdc Up to 15 Watts
AF-2X Any date code +23Vdc to +54Vdc Up to 17 Watts
AF-3X Any date code +23Vdc to +54Vdc Up to 17 Watts
AF-4X Any date code +23Vdc to +54Vdc Up to 17 Watts
AF-11FX Any date code +32Vdc to +54Vdc Up to 35 Watts
AF-24 Any date code +42Vdc to +58Vdc, -48Vdc Up to 50 Watts
AF-24HD Any date code +42Vdc to +58Vdc, -48Vdc Up to 50 Watts
AF-5/5U Any date code +42Vdc to +58Vdc, -48Vdc Up to 40 Watts 
AF-5XHD Any date code +19Vdc to +54Vdc Up to 15 Watts
AF60 Any date code +22 to +26VDC Up to 11 Watts
AF60-LR Any date code 48VDC ± 10% Up to 18 Watts

Some additional notes regarding airFiber power & input voltages follow below:

  • 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.
