AF11-Complete Quick Start Guide

(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.
(Recommended) Surge protection should be used for all outdoor installations. We
recommend that you use two Ethernet Surge Protectors, model ETH-SP-G2, one
within one meter of the device and the other at the entry point to the building. The
ETH-SP-G2 will absorb power surges and safely discharge them into the ground.
Hardware Overview
Note: The AF-11 radio has one Duplexer pre-installed for SISO mode. For
MIMO mode, a second Duplexer must be purchased separately. The
Duplexer(s) must match the terms of your license (frequency bands and
polarities allowed).
Note: For guidelines about grounding and lightning protection, follow your
local electrical regulatory codes.

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 flash. This continues until
the device is fully booted.
Signal Level Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how
close the device is to ideal aiming. This is auto-scaled based on the link range, the
antenna gains, and the configured TX power of the remote device. 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 flash; a
2 dB loss and the Signal 4 LED will turn off. The full bar graph LED states are shown
below.

Connect the DATA port to your LAN, and connect power (PoE or DC power) to the
radio.
Establish and optimize the RF link.
Installing the Duplexers
SISO Mode Installation
Each AF-11 radio already contains one Low-Band Duplexer or one High-Band Duplexer
for SISO mode. However, before you install the radios, you must ensure that Duplexers
in the paired radios are positioned in the reverse order from each other.
Note: For example, if the numbers on the first radio’s Duplexer are (left to right)
1/3, then the numbers on the second radio’s Duplexer should be 3/1.
Radio 1 Radio 2
Ensure that the Duplexers in your paired radios are installed in this manner. For
instructions on how to access the Duplexers and remove or install them, see “MIMO
Mode Installation”.
MIMO Mode Installation
Note: MIMO operation requires two licenses, one per polarization, and two
Duplexers of the same band type.
1.
2.
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.

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.
4.
5.
6. Repeat steps 1-5 for the other radio in the link, ensuring that the numbers on the
second radio’s Duplexers are in the reverse order of the numbers on the first radio’s
Duplexers.
Note: For example, if the numbers on the first 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.

Alignment
Tips
To accurately align the airFiber radios for best performance, 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-11G35:
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 four flange nuts on the two pole clamps.
b. Rotate the antenna to point towards the other end of the link.
c. Tighten the four flange nuts on the two pole clamps.
