Installation Requirements

Pre-Assembly Tool

• 13 mm (½") 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 (3.28 ft) below the highest point on the structure

• For tower installations, at least 3 m (9.84 ft) below the top of

thetower

• Ground wires – min. 10 AWG (5 mm
1m(3.28ft). 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.

) and max. length:

• 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 AF5 and AF5U 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.)

airFiber® AF5/AF5U Quick Start Guide

2. Connect an Ethernet cable to the Data port.

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

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.

airFiber® AF5/AF5U Quick Start Guide

1. Connect an Ethernet cable from your computer to the
Management port on the airFiber radio.

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. Click the Wireless tab.

6. Enter the Basic Wireless Settings:

a. For one airFiber radio, select Master from the Wireless Mode

drop-down. 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.

7. 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).

8. Click Change and then click Apply.

9. 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.
