airFiber® AF24 User Guide Chapter 2: Installation Alignment Using the LED Display Tips Establishing a Preliminary Link • We recommend using a pair of installers in constant communication because in the fine‑tuning stage, one installer makes azimuth and elevation adjustments on one airFiber radio while the other installer reports the received signal level at the other airFiber radio.
airFiber® AF24 User Guide Chapter 2: Installation 3. Master Aim the Master at the Slave. If necessary, adjust the Master’s position on the pole: a. Loosen the Hex Nuts. b. Adjust the Pole Mount Bracket and Pole Clamps. c. Tighten the Hex Nuts. 5. Master Adjust the azimuth and elevation of the Master until the strongest received signal level is displayed on the LED Display of the Master. a. Sweep the Azimuth (AZ) Adjustment Bolt of the Master through its adjustment range.
airFiber® AF24 User Guide 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.

Sweep the Elevation (EL) Adjustment Bolt of the Master through its adjustment range.
airFiber® AF24 User Guide Chapter 3: Navigation The airFiber Configuration Interface is an advanced operating system capable of powerful wireless and routing features, built upon a simple and intuitive user interface foundation. The airFiber AF24 uses the airFiber Configuration Interface for easy configuration and management via a web browser. There are two ways to access the airFiber Configuration Interface: Chapter 3: Navigation 3. Launch your web browser. Type http://192.168.1.
airFiber® AF24 User Guide Product Verification The airFiber Configuration Interface will verify whether a product is genuine or counterfeit. For a genuine airFiber AF24, the airFiber Configuration Interface will display a Genuine Product logo in the lower left corner of the screen.
airFiber® AF24 User Guide Chapter 4: Main Tab The Main tab displays a summary of the link status information, current values of the basic configuration settings, network settings and information, and traffic statistics. Status Chapter 4: Main Tab Device Name Displays the customizable name or identifier of the device. The Device Name (also known as host name) is displayed in registration screens and discovery tools. Operating Mode Displays the mode of the airFiber AF24: Slave, Master, or Reset.
airFiber® AF24 User Guide Chapter 4: Main Tab Chain 0/1 Signal Strength Displays the absolute power level (in dBm) of the received signal for each chain. Changing the RX Gain on the Wireless tab does not affect the Signal Strength values displayed on the Main tab. However, if “Overload” is displayed to indicate overload condition, decrease the RX Gain. See “RX Gain” on page 24 for more details about RX Gain and overload condition.
airFiber® AF24 User Guide Latitude/Longitude Based on GPS tracking, reports the device’s current latitude and longitude. Clicking the link opens the reported latitude and longitude in a browser using Google Maps™ (http://maps.google.com). Altitude Based on GPS tracking, reports the device’s current altitude relative to sea level. Chapter 4: Main Tab Log When logging is enabled (see “System Log” on page 33 to enable logging), this option lists all registered system events.
airFiber® AF24 User Guide Chapter 5: Wireless Tab The Wireless tab contains everything needed to set up the wireless part of the link. This includes wireless mode, link name, frequencies, output power, speed, gain, and wireless security. Chapter 5: Wireless Tab Write down the settings you configure on the Wireless tab. You will need to enter the same settings on the airFiber AF24 at the other end of your PtP link.
airFiber® AF24 User Guide Basic Wireless Settings In this section, configure the basic wireless settings, such as wireless mode, link name, country code, frequencies, output power, speed, and gain. Chapter 5: Wireless Tab Duplex Select Half Duplex or Full Duplex. Half-duplex operation provides more frequency planning options at the cost of higher latency and throughput. (Half‑duplex mode allows communication in one direction at a time, alternating between transmission and reception.
airFiber® AF24 User Guide Chapter 5: Wireless Tab RX Gain Select the appropriate gain for your RX antenna: High (default) or Low. If the link is very short or being tested, select Low, so your signal does not get distorted. Note: Minimum link distance is approximately 100 m (328 ft). For links between 100 m (328 ft) and 800 m (2,625 ft): • Target -40 dBm. • Decrease RX Gain to overcome overload condition ( ).
airFiber® AF24 User Guide Chapter 6: Network Tab The Network tab allows you to configure settings for the management network. There are two ways to access the airFiber Configuration Interface: • Config Port Enabled by default. Use a direct connection to the Config port for out-of-band management. • In-Band Management Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.
airFiber® AF24 User Guide • Static Assign static IP settings to the airFiber AF24. Note: IP settings should be consistent with the address space of the airFiber AF24’s network segment. Chapter 6: Network Tab The Auto IP Aliasing setting can be useful because you can still access and manage devices even if you lose, misconfigure, or forget their IP addresses.
airFiber® AF24 User Guide Chapter 7: Advanced Tab Chapter 7: Advanced Tab DATA Port Ethernet Settings The Advanced tab handles advanced wireless and Ethernet settings. These settings should not be changed unless you know the effects the changes will have on the airFiber AF24. Change To save or test your changes, click Change. A new message appears. You have three options: • Apply To immediately save your changes, click Apply. • Test To try the changes without saving them, click Test.
airFiber® AF24 User Guide Chapter 7: Advanced Tab Multicast Filter If enabled, the filter blocks multicast traffic from overloading the CPU when in-band management is enabled. This allows the airFiber AF24 to be managed in-band when the customer’s network is carrying large volumes of multicast traffic, such as IPTV. The filter does not block multicast traffic going over the radio; it simply blocks it from reaching the airFiber’s management interface CPU.
airFiber® AF24 User Guide Chapter 7: Advanced Tab • Enabled This option is designed for use by operators who are not using in-band management. The Track Radio Link option is enabled without timers, so the Data port’s Ethernet link follows the RF link state exactly. If the RF link goes down, then the Ethernet link goes down and remains down until the RF link goes back up. MGMT Port Ethernet Settings MGMT Speed This is the speed of the Config port. By default, the option is Auto.
airFiber® AF24 User Guide Chapter 8: Services Tab Chapter 8: Services Tab Ping Watchdog The Services tab configures system management services: Ping Watchdog, SNMP Agent, Web Server, SSH Server, Telnet Server, NTP Client, Dynamic DNS, System Log, and Device Discovery. Ping Watchdog sets the airFiber AF24 to continuously ping a user-defined IP address (it can be the Internet gateway, for example).
airFiber® AF24 User Guide Chapter 8: Services Tab For the purpose of equipment identification, configure the SNMP Agent with contact and location information: SNMP Agent Enables the SNMP Agent. Ping Watchdog Enables use of Ping Watchdog. • IP Address To Ping Specify the IP address of the target host to be monitored by Ping Watchdog. • Ping Interval Specify the time interval (in seconds) between the ICMP echo requests that are sent by Ping Watchdog.
