4.2 Mounting
Use the included mounting kits to securely attach the access point to a ceiling or wall. Refer to the detailed Installation Guide provided in your package for specific steps and safety precautions.
4.3 Initial Configuration
The EAP660 HD can be managed in two primary modes:
- Standalone Mode: Configure the access point directly via its web interface.
- Omada SDN Integration: For centralized management, integrate the EAP660 HD into an Omada SDN network using a Hardware Controller, Software Controller, or Cloud-based Controller. This is recommended for multi-device deployments.
For detailed configuration instructions, consult the official TP-Link Omada documentation or the User Guide PDF.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your EAP660 HD access point.
6.1 General Care
- Keep the device in a cool, dry environment, away from direct sunlight and heat sources.
- Clean the device periodically with a soft, dry cloth. Avoid using liquid cleaners or aerosols.
- Ensure proper ventilation around the device to prevent overheating.
6.2 Firmware Updates
Regularly update the device firmware to benefit from performance improvements, new features, and security enhancements. Firmware updates are typically managed through the Omada SDN Controller interface.
6.3 Scheduled Reboots
Consider configuring scheduled reboots through your Omada controller to maintain optimal performance and address potential minor issues proactively.
7. Troubleshooting
This section addresses common issues you might encounter with your EAP660 HD.
7.1 No Power/LED Indicator Off
- Ensure the Ethernet cable is securely connected to both the EAP660 HD and the PoE+ switch/injector.
- Verify that the PoE+ switch/injector is powered on and functioning correctly.
- If using the power adapter, ensure it is properly connected to the device and a working power outlet.
7.2 No Internet Connection
- Check the connection between the EAP660 HD and your router/gateway.
- Verify that your router/gateway has an active internet connection.
- Ensure the EAP660 HD is properly configured (e.g., correct IP settings, SSID broadcast).
7.3 Poor Wi-Fi Performance/Slow Speeds
- Check for sources of interference (e.g., microwaves, cordless phones, neighboring Wi-Fi networks).
- Ensure the access point is optimally placed, avoiding obstructions.
- Verify that your client devices support Wi-Fi 6 for optimal performance.
- If using Omada SDN, check channel utilization and adjust Wi-Fi settings (e.g., channel, channel width, transmit power).
7.4 Omada SDN Compatibility Issues
For SDN usage, ensure your Omada devices/controllers are either equipped with or can be upgraded to an SDN-compatible firmware version. SDN controllers work only with SDN APs, Switches, and Gateways. Non-SDN controllers work only with non-SDN APs. Refer to the TP-Link website for a list of compatible devices and firmware versions.
