AF-11 Quick Start Guide
(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- 11DUP-L) are required for proper operation:
SISO mode: One Duplexer of either band type MIMO mode: Two Duplexers of the same band type
Note: Duplexers must be purchased separately. The Duplexer(s) must match the terms of your license (frequency bands and polarities allowed).
(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

AF-11 Quick Start Guide

Low-Band Duplexer

High-Band Duplexer

Chain 0 / Chain 1
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 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, 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.

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 AF11. Establish and optimize the RF link.

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. 1.

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.

AF-11 Quick Start Guide
a. For the Management IP Address option: DHCP Keep the default, DHCP, to use DHCP reservation on your router to 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.
Con guration of the AF-11 radio is complete. Repeat the instructions in the airFiber Con guration section on the other AF-11 radio. For details on the airFiber Con guration Interface, refer to the airFiber AF-11FX User Guide, available at: ui.com/download/air ber
Hardware Installation Install a Ground Wire

AF-11 Quick Start Guide
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. 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. 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.

3. If you are using DC power, connect the other end of the Ethernet cable to your LAN.
Connecting Power
Follow the instructions for the source of power that you are using: Power over Ethernet or DC Power.
Power Over Ethernet
WARNING: Use only the included adapter, model POE-50-60W. Failure to do so can damage the unit and void the product warranty.
DC Power
1. Connect a DC power cable to the Terminal Block. ( The +VDC and GND can be connected to either terminal.)

AF-11 Quick Start Guide
2. Connect the other end of the DC power cable to a DC power supply that supplies +50VDC. WARNING: Applying a negative voltage such as -48VDC will damage the radio.
3. Connect the DC power supply to its source.
Surge Protection
For added protection, install two surge suppressors, such as the Ubiquiti Ethernet Surge Protector, model ETH-SP-G2, at the end of each link. Install the rst 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.

AF-11 Quick Start Guide
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 signi cant 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 rst at the Slave because the Slave does not

transmit any RF signal until it detects transmissions from the Master. AF-11 Quick Start Guide

Master 1.

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 ange nuts on the two pole clamps.

b. Rotate the antenna to point towards the other end of the link. c. Tighten the four ange nuts on the two pole clamps.

Adjust the elevation angle: a. Loosen the eight hex head bolts to so that the washers can spin freely by hand. b. Tighten or loosen the Elevation Adjustment Bolt to set the desired tilt. c. Tighten the eight hex head bolts.

AF-11 Quick Start Guide
Note: Do NOT make simultaneous adjustments on the Masterand 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 AF-11 Quick Start Guide
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, nalize the alignment of each airFiber antenna again, and retighten the nuts and bolts.
