Setup
- Identify Ports: The U-POE-AF adapter has two Ethernet ports. One port is typically labeled "LAN" or "Data In" and connects to your network switch or router. The other port is labeled "PoE" or "Data + Power Out" and connects to your PoE-compatible device (e.g., wireless access point).
- Connect to Network: Connect an Ethernet cable from your network switch or router to the "LAN" or "Data In" port on the U-POE-AF adapter.
- Connect to Device: Connect another Ethernet cable from the "PoE" or "Data + Power Out" port on the U-POE-AF adapter to the Ethernet port of your wireless mesh device.
- Power On: Plug the power cord of the U-POE-AF adapter into a standard electrical outlet. The adapter will then supply power and data to your connected PoE device.
- Verify Connection: Check the status indicators on both the adapter and your connected device to ensure a successful power and data link.
Operating Instructions
Once properly set up, the Ubiquiti U-POE-AF adapter operates automatically. It provides continuous power and data connectivity to the connected PoE device as long as it is plugged into a power source and connected to the network.
- Ensure the adapter is placed in a well-ventilated area to prevent overheating.
- Do not obstruct the ventilation openings.
- Avoid exposing the adapter to moisture or extreme temperatures.
Maintenance
The Ubiquiti U-POE-AF PoE Adapter requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Cleaning: Use a soft, dry cloth to clean the exterior of the adapter. Do not use liquid cleaners or aerosol sprays.

- Cable Management: Ensure Ethernet cables are not kinked or excessively bent, which can damage the internal wires.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to connected device. | Adapter not plugged in; faulty power outlet; incorrect cable connection; device not PoE compatible. | Ensure adapter is securely plugged into a working outlet. Verify Ethernet cables are correctly connected to the "LAN" and "PoE" ports. Confirm your device supports PoE. |
| No data connection. | Faulty Ethernet cable; network issue; incorrect port connection. | Test Ethernet cables. Check network switch/router status. Ensure the "LAN" port is connected to the network and "PoE" to the device. |
| Adapter is hot. | Poor ventilation; excessive load. | Ensure adequate airflow around the adapter. Do not cover it. If overheating persists, disconnect and contact support. |
