Connecting Power over Ethernet
1.  Lift the release latch on the bottom of the airFiberX 
radio and slide the Port Cover off.
2.  Connect an outdoor, shielded Ethernet cable to the 
DATA port.
3.  Connect the other end of the cable from the DATA port 
to the Ethernet port labeled POE on the airFiber PoE 
Adapter.
WARNING: Use only the included airFiber PoE 
Adapter, Model: GP-H240-100G-4. Failure to do 
so can damage the unit and void the product 
warranty.
4.  Connect an Ethernet cable from your LAN to the 
adapter’s LAN port.
5.  Connect the Power Cord to the adapter’s power port. 
Connect the other end of the Power Cord to a power 
outlet.
Mount the PoE Adapter (Optional)
1.  Remove the Mounting Bracket from the adapter, place 
the bracket at the desired location, and mark the  
two holes. 
2.  Pre-drill the holes if necessary, and secure the bracket 
using two fasteners (not included). 
3.  Align the adapter’s slots with the tabs of the Mounting 
Bracket, and then slide the adapter down.
Surge Protection
For added protection, install two surge suppressors, such 
as the Ubiquiti Ethernet Surge Protector, model ETH-SP, 
at the end of each link. 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.
