Installation Requirements
The airFiber AF-5X radio operates only with an airFiber X
antenna or a converted RocketDish™ antenna.
airFiber X antenna models:
• AF-5G23-S45
• AF-5G30-S45
• AF-5G34-S45
Conversion Kit for RocketDish (RD-5G30/RD-5G34):
• AF-5G-OMT-S45
Other Requirements
• Clear line of sight between airFiber radios
• Clear view of the sky for proper GPS operation
• Vertical mounting orientation
• Mounting point:
• At least 1 m below the highest point on the structure
• For tower installations, at least 3 m below the top of
thetower
• Ground wires – min. 10 AWG (5 mm2) and max. length:
1m. Asa safety precaution, ground the airFiber radio to
grounded masts, poles, towers, or grounding bars.
WARNING: Failure to properly ground your
airFiber radio will void your warranty.
• (Recommended) 2 Outdoor Gigabit 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.

Management Port 10/100 Mbps, secured Ethernet port for
configuration. In-Band Management is enabled by default
in the airFiber Configuration Interface. When In-Band
Management is disabled, the MGMT port is the only port that
can monitor, configure, and/or update firmware.

LEDs
Signal LEDs
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, GPS, LINK,
and Signal 1-4 LEDs light on. Once the CPU code takes over, the
GPS, LINK, and Signal 1-3 LEDs turn off. Signal 4 LED remains on
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 flash. This continues until the AF-5X is fully
booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act as a
bar graph showing how close the AF-5X is to ideal aiming. This
is auto-scaled based on the link range, the antenna gains, and
the configured TX power of the remote AF-5X. Each Signal LED
has three possible states: On, Flashing, and Off. All Signal LEDs
would be solidly on in an ideal link. If the link has a 1 dB loss,
the Signal4 LED will flash; a 2 dB loss and the Signal 4 LED will
turn off. The full bar graph LED states are shown below.

Installation Overview
We recommend that you configure your paired AF-5X radios
before site installation. Below is an overview of the installation
with specific details in the following instructions:
• Connect the airFiber PoE Adapter to the DATA por t, and
connect your computer to the MGMTport.
• Configure the AF-5X.
• Install a ground wire and mount the AF-5X on an
airFiber X antenna.
• At the installation site, install the airFiber X antenna with the
mounted AF-5X radio (see the antenna’s Quick Start Guide
for installation instructions).
• Secure the ground wire and mount the GPS antenna.
• Establish and optimize the RF link.
Connecting Power over Ethernet
1. Lift the release latch on the bottom of the AF-5X and slide
the Port Cover off.
2. Connect an Ethernet cable to the DATA port.
3. Connect the Ethernet cable from the DATA port to the
Ethernet port labeled POE on the airFiber PoE Adapter.
WARNING: Use only the included airFiber PoE Adapter,
Model: GP-H240-100G-4. Failure to do so can damage
the unit and void the product warranty.
4. Connect the Power Cord to the power port on the airFiber
PoE Adapter. Connect the other end of the Power Cord to a
powersource.
