- Ubiquiti Networks U-POE-af PoE Injector
- Power Cord
- Wall Mount Bracket (removable)
Setup
Follow these steps to connect your U-POE-af PoE Injector:
- Connect the Power Cord: Plug the provided power cord into the power input of the U-POE-af injector and then into a standard electrical outlet. The LED indicator on the injector should illuminate, indicating power.
- Connect to Network (LAN): Connect an Ethernet cable from your network switch or router to the port labeled LAN on the PoE injector. This port carries data from your network.
- Connect to PoE Device: Connect another Ethernet cable from the port labeled PoE on the injector to your PoE-compatible device (e.g., access point, IP camera, VoIP phone). This port delivers both data and power to the connected device.

This image displays the Ubiquiti Networks U-POE-af PoE Injector. The device is white and rectangular, featuring two Ethernet ports on one end. One port is labeled 'LAN' and the other 'PoE', with a red lightning bolt icon next to 'PoE' indicating power output. The top surface shows the Ubiquiti logo and 'U-POE-af' text.
Optional Wall Mounting: The injector includes a removable bracket on the back for wall mounting. To mount, detach the bracket, secure it to the wall using appropriate fasteners (not included), and then slide the injector onto the mounted bracket.
Operating Instructions
Once properly connected, the U-POE-af injector will automatically provide power and data to your connected PoE-compatible device. The blue LED indicator on the injector signifies that the unit is powered on and operational.
The injector supports the 802.3af PoE standard, delivering up to 15 watts of power. Ensure your connected device is compatible with this standard to avoid damage or malfunction.
