Connecting Power over Ethernet
airFiber Configuration
The instructions in this section explain how to access the airFiber Configuration Interface and configure the following settings:
- Wireless Mode Configure one airFiber AF-24 as the Master and the other as the Slave.
- Duplex The airFiber AF-24 supports both half-duplex and full-duplex operation. Half-duplex operation provides more frequency planning options at the cost of higher latency and throughput. Full-duplex operation provides the highest throughput and lowest latency; however, you have fewer frequency management options.
- Half Duplex (default) 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.
- TX and RX Frequencies The TX Frequency on the Master must match the RX Frequency on the Slave, and vice versa.

- Click Change and then click Apply.
- 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:
- Click the Network tab.
- Change the IP Address, Netmask, and other settings to make them compatible with your network.
- 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
- Secure the other end of the ground wire to a grounded mast, pole, tower, or grounding bar.
Note: Orient the Pole Mount Bracket around the pole so it is aimed in the direction of the other airFiber AF-24. |
Note: Loosen, but do NOT remove the eight Lock Bolts located on the Alignment Bracket. |
WARNING: To prevent injury, ensure that all four screws are seated and fully tightened. |
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
- Fine-tuning is best achieved by a pair of installers with a dedicated, two-way communication link: one installer makes adjustments on one airFiber radio while the other installer reports the received signal level at the other airFiber radio. Fine-tuning (see "Fine-Tuning the Link") is necessary because the main lobe of the receiver is narrower than that of the transmitter, in both azimuth and elevation.
- To accurately align the airFiber radios for best performance, you MUST align only one end of the link at a time.
- For more convenient alignment, you may consider using long-range scopes (not included) temporarily attached to your airFiber radios.
- 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 the airFiber radios.
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. |
---|
- For the Master and Slave, ensure the eight Lock Bolts on the Alignment Bracket are sufficiently loose by spinning each washer by hand.
- For the Master and Slave, ensure the Azimuth (AZ) and Elevation (EL) Adjustment Bolts are in the middle of their adjustment ranges.
- Master Aim the Master at the Slave. If necessary, adjust the Master's position on the pole:
- Loosen the Hex Nuts.
- Adjust the Pole Mount Bracket and Pole Clamps.
- Tighten the Hex Nuts.
- Loosen the Hex Nuts.
- 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.
- Master Adjust the azimuth and elevation of the Master until the strongest received signal level is displayed on the LED Display of the Master.
- Sweep the Azimuth (AZ) Adjustment Bolt of the Master through its adjustment range.
- Sweep the Elevation (EL) Adjustment Bolt of the Master through its adjustment range.
- Sweep the Azimuth (AZ) Adjustment Bolt of the Master through its adjustment range.
WARNING: All Lock Bolts MUST be loose to avoid damage to the airFiber housing. |
|
Note: If the LED Display indicates an overload condition |

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.
- 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.
- 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.
- 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.
- Lock the alignment on both airFiber radios by tightening all eight Lock Bolts on the Alignment Bracket.
- 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.
- 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:
- LED Display (described above)
- airFiber Configuration Interface
- Audio tone (optional equipment required)
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
