airFiber® AF-24HD Quick Start Guide
Installation Requirements
•17 mm wrench
•13 mm socket wrench or driver
•Clear line of sight between airFiber radios
•Clear view of the sky for proper GPS operation
•Mounting location with < 0.5° displacement due to twist and sway under wind loading
•Mounting point:
•At least 1 meter below the highest point on the structure
•For tower installations, at least 3 meters below the top of the tower
•Ground wires – min. 8 AWG (10 mm2) and max. length: 1 meter.
As a safety precaution, ground the airFiber radios to grounded masts, poles, towers, or grounding bars.
WARNING: Failure to properly ground your airFiber units will void your warranty.
•(Recommended) 2 Outdoor Gigabit PoE surge protectors – Ubiquiti Ethernet Surge Protector, model ETH-SP.
Note: For guidelines about grounding and lightning protection, follow your local electrical regulatory codes.
•Outdoor, shielded Category 5e (or above) cabling and shielded RJ-45 connectors should be used for all wired Ethernet connections. Category 6 is required for installations with long cable runs (up to 100 m).
We recommend that you protect your networks from the most brutal environments and devastating ESD attacks with industrial grade shielded Ethernet cable and shielded RJ-45 connectors from Ubiquiti Networks. For more details, visit www.ubnt.com/toughcable

Installation Overview
Installation Overview
We recommend that you configure your paired airFiber radios before mounting. Below is an overview of the installation with specific details on the following pages:
•Connect Power over Ethernet to the DATA port, and connect an Ethernet cable between your computer and the CONFIG port.
•Configure device settings in the airFiber Configuration Interface.
•Once configuration is complete, disconnect the cables to move the airFiber radios.
•Reconnect at the site.
•After you have mounted the airFiber radios, establish and optimize the RF link.
Connecting Power over Ethernet
1.Turn the Cover Lock to the Unlocked 
icon. Slide the Port Cover down to remove it.

2. Connect an Ethernet cable to the DATA port.
3.Connect the other end of the Ethernet cable from the DATA port to the Ethernet port labeled POE on the Gigabit PoE Adapter.
4.Connect the Power Cord to the power port on the Gigabit PoE Adapter. Connect the other end of the Power Cord to a power source.

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-24HD as the Master and the other as the Slave.
•Duplex The airFiber AF-24HD 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.

airFiber® AF-24HD Quick Start Guide
1.Connect an Ethernet cable from your computer to the CONFIG port on the airFiber AF-24HD.
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.The login screen will appear. 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.
