Installation Requirements
Pre-Assembly Tool
• 13 mm wrench
Pole-Mounting Tool
• 17 mm wrench
Other Requirements
• Clear line of sight between airFiber radios
• Clear view of the sky for proper GPS operation
• Vertical mounting orientation
• Mounting location with < 0.5°displacement due to twist and
sway under wind loading
• Mounting point:
• At least 1 m below the highest point on the structure
• For tower installations, at least 3 m below the top of thetower
• Ground wires – min. 10 AWG (5 mm2) and max. length: 1m.
Asa safety precaution, ground the airFiber radios to grounded
masts, poles, towers, or grounding bars.
WARNING: Failure to properly ground your airFiber
units will void your warranty.
• (Recommended) 2 Outdoor GigE PoE surge protectors
Note: For guidelines about grounding and lightning
protection, follow your local electrical regulatory codes.
• Outdoor, shielded Category 6 (or above) cabling and
shielded RJ-45 connectors are required for all wired Ethernet
connections.

Installation Overview
Installation Overview
We recommend that you configure your paired airFiber radios
before mounting. Below is an overview of the installation with
specific details in the following instructions:
• Connect Power over Ethernet to the Data port, and
connect an Ethernet cable between your computer and the
Managementport.
• Configure the device settings in the airFiber Configuration
Interface.
• Once configuration is complete, disconnect the cables to move
the airFiber radios.
• Pre-assemble the mounting hardware.
• Install the airFiber radios at the site.
• Establish and optimize the RF link.
Note: The AF-5 and AF-5U models share the same
installation and configuration instructions.
Connecting Power over Ethernet
1. Push the button and slide the port cover down to access
cableports. (The port cover cannot be completely removed.)

3. Connect the other end of the Ethernet cable from the Data
port to the Ethernet port labeled POE on the GigE PoE Adapter.
4. Connect the Power Cord to the power port on the GigE
PoE Adapter. Connect the other end of the Power Cord to a
powersource.

airFiber Configuration
airFiber Configuration
The instructions in this section explain how to access the airFiber
Configuration Interface and configure the following settings:
• Wireless Mode Configure one airFiber radio as the Master and
the other as the Slave.
• Duplex The airFiber radio supports both half-duplex and
full-duplex operation. Half-duplex operation provides more
frequency planning options at the cost of higher latency
and throughput. Full-duplex operation provides the highest
throughput and lowest latency; however, you have fewer
frequency management options.
- Half Duplex (default) The TX and RX Frequencies can be the
same or different to suit local interference.

2. Configure the Ethernet adapter on your computer with a static
IP address on the 192.168.1.x subnet.
3. Launch your web browser. Type http://192.168.1.20 in the
address field and press enter (PC) or return (Mac).
4. The login screen will appear. Enter ubnt in the Username and
Password fields. Select your Country and Language. You must
agree to the Terms of Use to use the product. Click Login.
Note: U.S. product versions are locked to the U.S. Country
Code to ensure compliance with FCC regulations.

5. The Main tab will appear. Click the Tools drop-down and
select Link Calculator. This tool will guide you on how to best
minimize bandwidth and power/interference issues.
Note: If you do not see the Link Calculator, then upgrade
the firmware on your airFiber radios. Download the
firmware at: downloads.ubnt.com/airfiber
6. Enter the requirements of your link, and then click Calculate.
Adjust the values as needed to get the optimal result, and then
write down the settings needed for your configuration.
7. Click the Wireless tab.
8. Enter the Basic Wireless Settings:
a. For one airFiber radio, select Master as the Wireless Mode.
For the other airFiber radio, keep the default,Slave.
b. Enter a name in the Link Name field. This should be the
same on both the Master and the Slave.
c. For the Duplex drop-down:
- Half Duplex The default mode. The TX and RX Frequencies
can be the same or different to suit local interference.
- Full Duplex The TX and RX Frequencies should be different.
d. Select a TX Frequency. This must match the RX Frequency on
your other airFiber radio.
e. Select a RX Frequency. This must match the TX Frequency of
your other airFiber radio.
f. If needed, change the Output Power and/or Maximum
Modulation Rate settings.

9. Configure the Wireless Security:
a. Select the AES Key Type, HEX or ASCII.
b. For the Key field:
- HEX Enter 16 bytes (eight, 16-bit HEX values: 0-9, A-F, or
a-f). You can omit zeroes and use colons, similar to the
IPv6 format.
Note: The airFiber Configuration Interface supports
IPv6 formats excluding dotted quad and "::"
(double-colon) notation.
- ASCII Enter a combination of alphanumeric characters (0-9,
A-Z, or a-z).
10. Click Change and then click Apply.
11. In-Band Management is enabled by default, so each airFiber
radio must have a unique IP Address. (If the airFiber radios use
the same IP Address, then you may lose access to the airFiber
radios via the Data ports.) Click the Network tab.
a. For the Management IP Address option:
- DHCP Keep the default, DHCP, to use DHCP reservation on
your router to assign a unique IP Address.
- Static Change the IP Address, Netmask, and other settings
to make them compatible with your network.
b. Click Change and then click Apply.
Repeat the instructions in the airFiber Configuration section on
your other airFiber radio. After you have configured the airFiber
radios, disconnect them and move them to your installation site.
