Configure the airFiber 5X Radio
Note: The airFiber 5X radios must be running
airOS®F v3.2.1 or newer. The latest firmware is
available at: downloads.ubnt.com/airfiber
Each airFiber 5X radio must be preconfigured for use with
the airFiberNxN before installing them at the site.
Enable airFiber NxN support on each radio:
1. Log into the airOS F Configuration Interface.
2. Click the Wireless tab.
3. Enter the additional Cable Loss value (dB):
a. 4.1 for the AF-MPx4, or
b. 7.2 for the AF-MPx8
4. For the NxN Radio setting, select Enable.
5. Click Change, and then click Apply.
Hardware Installation
The following installation shows the AF-MPx8. For the
AF-MPx4 installation, only the mounting and connecting
of two airFiber 5X radios apply.
1. (For AF-MPx8 only) Attach the 8x8 Radio Bracket to the
4x4 Radio Bracket using four M3x8 Screws.
2. Seat the airFiber NxN Multiplexer into the 4x4 Radio
Bracket either at (a) a 15° angle or (b) vertically:
a. For most antenna models, the airFiber NxN
Multiplexer should be installed at a 15° angle. Insert
the airFiber NxN Multiplexer from behind the 4x4
Radio Bracket and slide the 15° Angle Tabs into the
slots on the bracket.
15° Angle Tab
b. For other antenna configurations that require the
airFiber NxN assembly to be mounted to a pole, the
airFiber NxN Multiplexer must be installed vertically.
Insert the airFiber NxN Multiplexer from behind the
4x4 Radio Bracket and slide the Vertical Tabs into the
slots on the bracket.
