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 Signal4 LED will flash; a 2 dB loss and the Signal4
LED will turn off. The full bar graph LED states are shown below.

Mount to an airFiber X Antenna

Follow the instructions in this section to mount the AF-5XHD
to an airFiber X antenna or to a RocketDish antenna equipped
with the AF-5G-OMT-S45 Conversion Kit.

Note: To mount the AF-5XHD to a RocketDish using the

included Universal Bracket, see the Mount to a RocketDish
Antenna section.

The airFiber X antenna AF-5G23-S45 is shown in this section:

1. Attach the airFiber X radio to the antenna by aligning the
four tabs on the back of the radio with the slots of the radio
mount. Then slide the radio down to lock it into place.

2. Attach the RF connectors to the radio in this combination:
+45° to Chain0 and -45° to Chain 1. Then slide the jackets
over the RF connectors to protect them.

3. Attach the external GPS antenna (included with the radio)
to the RF connector labeled GPS on the radio.

4. Attach the Protective Shroud by sliding it down over the
radio until it locks into the radio mount.

Mount to a RocketDish Antenna

Note: If you are mounting the AF-5XHD on a RocketDish

equipped with the AF-5G-OMT-S45 Conversion Kit, the

Universal Bracket is not needed. Refer instead to the
Mount to an airFiber X Antenna section for instructions.

The RocketDish RD-5G30 antenna is shown in this section:

1. Position the Universal Bracket over the back of the AF-5XHD
with the bracket clips over the AF-5XHD mounting tabs.

2. Push the bracket onto the AF-5XHD until it locks in place.

3. Attach the AF-5XHD to the RocketDish mounting bracket.

a. Align the mounting tabs on the Universal Bracket with

the RocketDish mounting bracket.

b. Slide the AF-5XHD down to lock it into place.

Mount the External GPS Antenna

Locate a mounting point that has a clear view to the sky, and is
above and as far away as possible from the AF-5XHD.

1. Attach the GPS Antenna Mount to the pole using the Metal
Strap, or attach it to a wall using the appropriate fasteners

(notincluded).

2. Place the External GPS Antenna on the mount.

3. Secure the cable of the External GPS Antenna to the mount
with a Zip Tie.

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 outdoor, shielded Ethernet cable to the
Dataport.

Note: If the IP67 Upgrade Kit is installed, first apply

dielectric grease to the connector and 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 an Ethernet cable from your LAN to the adapter’s
LAN port.

5. Connect the Power Cord to the adapter’s power port.
Connect the other end of the Power Cord to a power outlet.

Mount the PoE Adapter (Optional)

1. Remove the Mounting Bracket from the adapter, place the
bracket at the desired location, and mark the two holes.

2. Pre-drill the holes if necessary, and secure the bracket
using two fasteners (not included).

3. Align the adapter’s slots with the tabs of the Mounting
Bracket, and then slide the adapter down.

Surge Protection

For added protection, install two surge suppressors, such as
the Ubiquiti Ethernet Surge Protector, model ETH-SP, at the
end of each link. Install the first surge protector within one
meter of the airFiber Data port, and install the second surge
protector at the ingress point of the location housing the
wired network equipment.

Alignment

Tips

• To accurately align the airFiber radios for best per formance,
you MUST align only one end of the link at a time.

• You may need to use additional hardware to compensate for
issues such as the improper orientation of a mounting pole
or significant elevation differences between airFiber radios.

Establishing a Link

Adjust the positions of the Master and the Slave to establish
a link. The following section features the airFiber X antenna,
AF-5G23-S45:

Note: The Master must be aimed first at the Slave because

the Slave does not transmit any RF signal until it detects
transmissions from the Master.

1. Master Visually aim the Master at the Slave. To adjust the

Master’s position, adjust the azimuth and the elevation.

Adjust the azimuth:

a. Loosen the two Flange Nuts on the U-Bolt.
b. Rotate the antenna to point towards the other end of

the link.

c. Tighten the two Flange Nuts.

The elevation angle may be adjusted ±15°. Adjust the
elevation angle:

d. Loosen the four Hex Bolts on both sides of the antenna.

e. Pivot the antenna to the desired elevation.

f. Tighten the four Hex Bolts.

Note: Do NOT make simultaneous adjustments on

the Master and Slave.

2. Slave Visually aim the Slave at the Master. To adjust the

Slave’s position, adjust the azimuth and elevation as
described in step 1.

3. Check to see if a link is established. Ensure that the Link

LED is solidly lit green and the Signal LEDs of the Slave are
displaying signal levels.

4. Slave Aim the Slave at the Master to achieve the strongest

signal level on the Master.

Note: Refer to the Signal LEDs section for details on

the signal values.

Note: Maximum signal strength can best be achieved

by iteratively sweeping through both azimuth and
elevation.

5. Master Aim the Master at the Slave to achieve the

strongest signal level on the Slave.

6. Repeat steps 4 and 5 until you achieve an optimal link, with

all four Signal LEDs solidly lit. This ensures the best possible
data rate between the airFiber radios.

7. Lock the alignment on both airFiber antennas by

tightening all the nuts and bolts.

8. Observe the Signal LEDs of each airFiber radio to ensure

that the values remain constant while tightening the nuts
and bolts. If any LED value changes during the locking
process, loosen the nuts and bolts, finalize the alignment
of each airFiber antenna again, and retighten the nuts
and bolts.

Installer Compliance Responsibility

Devices must be professionally installed and it is the
professional installer’s responsibility to make sure the device is
operated within local country regulatory requirements.

The Frequency, Output Power, Antenna Gain, and Cable Loss
fields are provided to the professional installer to assist in
meeting regulatory requirements.
