Installation Requirements

Connecting Power over Ethernet

airFiber Configuration

The instructions in this section explain how to access the airFiber Configuration Interface and configure the following settings:

  1. Connect an Ethernet cable from your computer to the Config port on the airFiber AF-24.

  2. Configure the Ethernet adapter on your computer with a static IP address on the 192.168.1.x subnet (for example, 192.168.1.100).
  3. Launch your web browser. Type http://192.168.1.20 in the address field and press enter (PC) or return (Mac).

  4. Enter ubnt in the Username and Password fields. Select your Country and Language. You must agree to the Terms of Use to use the product. Click Login.

    Note: U.S. product versions are locked to the U.S. Country Code to ensure compliance with FCC regulations.

  5. Click the Wireless tab.

  6. Enter the Basic Wireless Settings:
    1. For one airFiber AF-24, select Master from the Wireless Mode drop-down. For the other airFiber AF-24, keep the default, Slave.
    2. Enter a name in the Link Name field. This should be the same on both the Master and the Slave.
    3. For the Duplex drop-down:
      • Half Duplex The default mode. The TX and RX Frequencies can be the same or different to suit local interference.
      • Full Duplex The TX and RX Frequencies should be different.
    4. Select a TX Frequency. This must match the RX Frequency of your other airFiber AF-24.
    5. Select a RX Frequency. This must match the TX Frequency of your other airFiber AF-24.
    6. If needed, change the Output Power, Maximum Modulation Rate, and/or RX Gain settings.
  7. Configure the Wireless Security:
    1. Select the AES Key Type, HEX or ASCII.
    2. For the Key field:
      • HEX Enter 16 bytes (eight, 16-bit HEX values: 0-9, A-F, or a-f). You can omit zeroes and use colons, similar to the
        IPv6 format.

        Note: The airFiber Configuration Interface supports IPv6 formats excluding dotted quad and "::" (double-colon) notation.

      • ASCII Enter a combination of alphanumeric characters (0-9, A-Z, or a-z).
  8. Click Change and then click Apply.
  9. 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, then you may lose access to the airFiber radios via the Data ports.) To change the network settings:
    1. Click the Network tab.

    2. Change the IP Address, Netmask, and other settings to make them compatible with your network.
    3. Click Change and then click Apply.

Repeat the instructions in the airFiber Configuration section on your other airFiber radio. After you have configured the airFiber radios, disconnect them and move them to your installation site.

Hardware Installation

  1. Note: Orient the Pole Mount Bracket around the pole so it is aimed in the direction of the other airFiber AF-24.

  2. Note: Loosen, but do NOT remove the eight Lock Bolts located on the Alignment Bracket.

  3. WARNING: To prevent injury, ensure that all four screws are seated and fully tightened.

  4. Secure the other end of the ground wire to a grounded mast, pole, tower, or grounding bar.
  5. WARNING: Failure to properly ground your airFiber units will void your warranty.

    Note: The ground wire should be as short as possible and no longer than one meter in length.

Connecting Ethernet

Note: For added protection, we recommend installing two GigE PoE surge protectors. 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.

Below is a diagram of a finished installation with recommended surge protectors installed.

Alignment

Tips

Establishing a Preliminary Link

Adjust the positions of the Master and the Slave to establish a preliminary link. This requires the Master and Slave to be within a few degrees of the line of sight between the airFiber radios.

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. For the Master and Slave, ensure the eight Lock Bolts on the Alignment Bracket are sufficiently loose by spinning each washer by hand.

  2. WARNING: All Lock Bolts MUST be loose to avoid damage to the airFiber housing.

  3. For the Master and Slave, ensure the Azimuth (AZ) and Elevation (EL) Adjustment Bolts are in the middle of their adjustment ranges.

  4. Master Aim the Master at the Slave. If necessary, adjust the Master's position on the pole:
    1. Loosen the Hex Nuts.

    2. Adjust the Pole Mount Bracket and Pole Clamps.
    3. Tighten the Hex Nuts.
  5. Slave Aim the Slave at the Master to achieve the strongest received signal level on the Slave's numeric LED Display, which is located next to the Config port. If necessary, adjust the Slave's position on the pole.

    Note: Values on the LED Display are displayed in negative (-) dBm. For example, 61 represents -61 dBm, which is stronger than -72 dBm.

  6. Master Adjust the azimuth and elevation of the Master until the strongest received signal level is displayed on the LED Display of the Master.
    1. Sweep the Azimuth (AZ) Adjustment Bolt of the Master through its adjustment range.

    2. Sweep the Elevation (EL) Adjustment Bolt of the Master through its adjustment range.

Note: If the LED Display indicates an overload condition , refer to the airFiber AF-24 User Guide at: ui.com/download/airfiber

Fine-Tuning the Link

The Azimuth (AZ) and Elevation (EL) Adjustment Bolts of the Alignment Bracket adjust the azimuth and elevation within a range of ±10°. For accurate alignment, make adjustments on one end of the link while the other installer reports the received signal level at the other end of the link. Do NOT make simultaneous adjustments on the Master and Slave.

  1. Slave Adjust the azimuth and elevation of the Slave until the other installer sees the strongest received signal level displayed on the LED Display of the Master.
  2. Master Adjust the azimuth and elevation of the Master until the other installer sees the strongest received signal level displayed on the LED Display of the Slave.
  3. Repeat steps 1 and 2 until you achieve a symmetric link, with the received signal levels within 1 dB of each other. This ensures the best possible data rate between the airFiber radios.
  4. Lock the alignment on both airFiber radios by tightening all eight Lock Bolts on the Alignment Bracket.
  5. Observe the LED Display of each airFiber AF-24 to ensure that the value remains constant while tightening the Lock Bolts. If the LED value changes during the locking process, loosen the Lock Bolts, finalize the alignment of each airFiber AF-24 again, and retighten the Lock Bolts.
  6. For each airFiber AF-24, attach the Port Cover and turn the Cover Lock to the Locked icon.

There are three methods for determining the received signal level:

Refer to the airFiber AF-24 User Guide for instructions on the airFiber Configuration Interface and audio tone methods. The User Guide is available at: ui.com/download/airfiber

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 TX Frequency, RX Frequency, and Output Power fields are provided to the professional installer to assist in meeting regulatory requirements.
