Antenna Compatibility
The airFiber AF-5XHD radio is designed for use with the
following airFiber X antenna models:
• AF-5G23-S45
• AF-5G30-S45
• AF-5G34-S45
The AF-5XHD can also operate with the following RocketDish™
antenna models:
• RD-5G30*
• RD-5G34*
* Requires Universal Bracket (included) or AF-5G-OMT-S45 Conversion Kit
(not included).
Installation 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
Management Port 10/100/1000 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. This port can
also be used to provide redundant PoE power.

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. The 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-5XHD
is fully booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act as a
bar graph showing how close the AF-5XHD 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-5XHD. 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 Signal4
LED will turn off. The full bar graph LED states are shown below.

Installation Overview
We recommend that you configure your paired AF-5XHD
radios before site installation. The overview below summarizes
the installation procedure, and the subsequent sections
provide detailed installation information.
• Connect the airFiber PoE Adapter to the Data port, and
connect your computer to the MGMTport.
• Configure the AF-5XHD.
• Recommended: Install the IP67 Upgrade Kit (included) to
prevent intrusion by water, dust, and insects.
• Install a ground wire and mount the AF-5XHD on an
airFiberX or RocketDish antenna.
• At the installation site, install the airFiber X or RocketDish
antenna with the mounted AF-5XHD 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-5XHD and
slide the Port Cover off.
2. Connect an Ethernet cable to the Data port.
3. Connect the Ethernet cable from the Data port of the
AF-5XHD to the POE port of the adapter.
WARNING: Use only the included adapter, model
POE‑24V‑5X‑HD. Failure to do so can damage the
unit and void the product warranty.
4. Connect the Power Cord to the adapter’s power port.
Connect the other end of the Power Cord to a poweroutlet.
