Installation Overview
Werecommend that you configure your paired airFiber radios
before mounting. Below is an overview of the installation with
specific details in the following instructions:
• Connect Power over Ethernet to the Data port, and
connect an Ethernet cable between your computer and the
Management port.
• Configure the devicesettingsinthe airFiber Configuration
Interface.
• Onceconfigurationiscomplete,disconnect thecables tomove
theairFiberradios.
• Pre-assemblethemountinghardware.
• InstalltheairFiberradiosatthesite.
• EstablishandoptimizetheRFlink.

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 GigE PoE Adapter.
4. Connect the Power Cord to the power port on the GigE
PoE Adapter. Connect the other end of the Power Cord to a

Configuration Interface and configure the following settings:
• WirelessMode ConfigureoneairFiberradioastheMaster and
the other as the Slave.
• Duplex The airFiber radio 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 thehighest
throughput and lowest latency; however, you have fewer
frequency managementoptions.
- Half Duplex (default) The TX and RX Frequencies can be the
same or different to suit local interference.
