(Recommended) 2 Outdoor Gigabit PoE surge protectors
Note: For guidelines about grounding and lightning protection, follow your
local electrical regulatory codes.
High-Band Duplexer(s) (model AF-11-DUP-H) or Low-Band Duplexer(s) (model AF-11-
DUP-L) are required for proper operation:
SISO mode: One Duplexer of either band type
MIMO mode: Two Duplexers of the same band type
(Optional) If not using PoE: DC power source and 12/30 AWG power cable
Outdoor, shielded Category 6 (or above) cabling and shielded RJ-45 connectors are
required for all wired Ethernet connections.
Hardware Overview
Note: Duplexers must be purchased separately. The Duplexer(s) must match
the terms of your license (frequency bands and polarities allowed).

When the Chain 0 or Chain 1 duplexer is installed, its N-type connector is located here,
allowing connection to an RF cable (Chain 1 is covered by the removable duplexer cap).

Signal 4 LED will light blue when on.
Signal 3 LED will light green when on.
Signal 2 LED will light yellow when on.
Signal 1 LED will light red when on.
Bootup to airOS When powering on, the Power, MIMO, LINK, and Signal 1-4 LEDs light
on. Once the CPU code takes over, the MIMO, LINK, and Signal 1-3 LEDs turn off. Signal
4 LED remains lit to indicate the boot sequence is underway.
Initializing airFiber Software When the airFiber application begins to boot under
airOS®, the Signal 4 LED goes from solidly on to a 2.5 Hz ash. This continues until the
AF ‐ 11FX is fully booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how
close the AF ‐ 11FX is to ideal aiming. This is auto-scaled based on the link range, the
antenna gains, and the congured TX power of the remote AF ‐ 11FX. Each Signal LED
has three possible states: On, Flashing, and Off. All Signal LEDs would be solidly on in an
ideal link. For example, if the link has a 1 dB loss, the Signal 4 LED will ash; a 2 dB loss
and the Signal 4 LED will turn off. The full bar graph LED states are shown below.

10/100 Mbps, secured Ethernet port for conguration. In-Band Management is enabled
by default in the airFiber Conguration Interface. When In-Band Management is
disabled, the MGMT port is the only port that can monitor, congure, and/or update
rmware.
To reset to factory defaults, press and hold the Reset button for more than 10 seconds
while the device is already powered on.
Gigabit PoE port for handling all user traffic and powering the device.
The terminal block can be used to power the AF-11 with +50VDC, 1.2A instead of PoE.
The TX and RX SMA ports for the Chain 0 Low-Band Duplexer or High-Band Duplexer

The RX and TX SMA ports for the Chain 1 Low-Band Duplexer or High-Band Duplexer
(MIMO mode only). In SISO mode, these unused ports are protected by the duplexer
cap.

High-band and low-band channel SMA ports.
Note: Duplexers are not included with the AF-11. SISO mode requires one Low-
Band Duplexer or one High-Band Duplexer. MIMO mode requires either two Low-
Band Duplexers or two High-Band Duplexers.
Installation Overview
We recommend that you congure your paired AF-11 radios before site installation. The
overview below summarizes the installation procedure, and the subsequent sections
provide detailed installation information.
Install the Duplexer(s) in the AF-11 radio.
Connect the airFiber Gigabit PoE adapter to the DATA port, and connect your computer
to the MGMT port.
Congure the AF-11.
Install a ground wire and mount the AF-11 on the airFiber AF-11G35 antenna (or a
compatible antenna).
At the installation site, install the antenna with the mounted AF-11 radio (see the
antenna’s Quick Start Guide for installation instructions).
Connect the DATA port to your LAN, and connect power (PoE or DC power) to the AF-
11.
Establish and optimize the RF link.

Note: Position the low channel and high channel ports to yield the required
transmit and receive frequencies.
3.
WARNING: Tighten the collars alternately, a half turn at a time, until both are
fully tightened. Failure to do so may result in damage to the Duplexer.

5. Repeat steps 1-4 for the radio to be used on the other end of the link, ensuring that the
numbers on the second radio’s Duplexer are in the reverse order of the numbers on rst
radio’s Duplexer.
Note: For example, if the numbers on the rst radio’s Duplexer are (left to right)
1/3, then the numbers on the second radio’s Duplexer should be 3/1.
Installing the Duplexers for MIMO Mode
Note: MIMO operation requires two licenses, one per polarization and two
Duplexers of the same band type.

Note: Position the low channel and high channel ports to yield the required
transmit and receive frequencies. Also, ensure that the numbers on the right-
side Duplexer are in the reverse order of the numbers on the left-side Duplexer.

6. Repeat steps 1-5 for the other radio to be used in the link, ensuring that the numbers on
the second radio’s Duplexers are in the reverse order of the numbers on the rst radio’s
Duplexers.
Note: For example, if the numbers on the rst radio’s Duplexers are (left to right)
2/4 and 4/2, the numbers on the second radio’s Duplexers should be 4/2 and 2/4.

5. Click Settings, and then click the Wireless tab.
6. Congure the Basic Wireless Settings:
a. For one AF-11, select Master as the Wireless Mode. For the other AF-11, keep the
default, Slave.
b. Enter a name in the Link Name eld. This should be the same on both the Master
and the Slave.
c. If needed, change the Channel Bandwidth, Output Power and/or Maximum
Modulation Rate settings.
7. Congure the TX Frequency and RX Frequency.
8. Congure the Wireless Security:
a. Select the Key Type, HEX or ASCII.
b. For the Key eld:
HEX Enter 16 bytes (eight, 16-bit hexadecimal digits: 0-9, A-F, or a-f). You can
omit zeroes and use colons, similar to the IPv6 format.
ASCII Enter a combination of alphanumeric characters (0-9, A-Z, or a-z).
9. Click Save Changes.
10. 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, you may lose
access to the airFiber radios via the DATA ports.) Click the Network tab.
Note: One airFiber radio’s TX Frequency is the other radio’s RX Frequency,
and vice versa.
Note: The airFiber Conguration Interface supports IPv6 formats
excluding dotted quad and “::” (double-colon) notation.

assign a unique IP Address.
Static Change the IP Address, Netmask, and other settings to make them
compatible with your network.
b. Click Save Changes.
11. Disconnect the Ethernet cables from the MGMT and DATA ports on the AF-11.

3. At the installation site, secure the other end of the ground wire to a grounded mast,
pole, tower, or grounding bar.
WARNING: Failure to properly ground your airFiber radio will void your
warranty.
Note: The ground wire should be as short as possible and no longer than one
meter in length.
Mount to the airFiber AF-11G35 Antenna
1. Attach an RF Cable to an RF connector labeled H or V. Then slide the silicone boot over
the RF connector to protect it.
If using MIMO mode, remove the cap over the second RF connector (V or H) and attach
an RF Cable. Then slide the silicone boot over the RF connector to protect it.
Note: For SISO mode, use the RF connector (H or V) as determined by your
licensing. Keep the other RF connector covered with the included Metal Cap.
