3.2 Power Supply
The CF-EW87 supports dual power supply modes: Power over Ethernet (POE) and DC power. Choose the method most suitable for your installation environment.
- POE Power Supply (Recommended): Connect an Ethernet cable from a 48V/0.32A POE injector or POE switch to the WAN port of the CF-EW87. This provides both power and data connectivity through a single cable.
- DC Power Supply: Connect a 12V/1.5A DC power adapter (not always included, check package contents) to the DC power supply interface on the device. Ensure the power adapter is suitable for outdoor use if exposed to elements.
3.3 Network Connection
The device features Gigabit Ethernet ports for high-speed network connectivity.
- WAN Port: Connect your internet source (e.g., modem, router, or POE switch) to the 10/100/1000Mbps RJ45 WAN Ethernet port.
- LAN Ports: The device has two 10/100/1000Mbps RJ45 LAN Ethernet ports. These can be used to connect other wired network devices or extend your network.
4. Operation
4.1 Initial Power-On and Status Indicators
Once powered on, the device will initiate its boot sequence. Observe the LED indicators on the front panel to monitor its status:
- Power LED: Indicates the device is powered on.
- WAN LED: Indicates activity on the WAN port.
- LAN LEDs: Indicate activity on the LAN ports.
- Wi-Fi LED: Indicates wireless functionality is active.
4.2 Wireless Connectivity
The CF-EW87 operates on dual bands (2.4GHz and 5.8GHz) with WiFi 7 (802.11BE) standard, offering a combined wireless rate of 3600Mbps. This allows for high-efficiency transmission and supports a large number of concurrent devices.
- Connecting Devices: Search for the Wi-Fi network name (SSID) broadcast by the CF-EW87 on your wireless devices and connect using the provided password.
- High Capacity: A single CF-EW87 AP can simultaneously connect over 120 terminal devices, ensuring smooth network access even in high-density environments.
4.3 Remote Management
For large-scale WiFi projects, the CF-EW87 can be paired with COMFAST brand AC management devices for centralized management and remote control of outdoor APs. This significantly reduces project debugging and maintenance costs, making network deployment and operation more efficient.
5. Maintenance
The COMFAST CF-EW87 is designed for outdoor use with an IP66 waterproof and dustproof rating, minimizing the need for extensive maintenance. However, regular checks can ensure optimal performance and longevity.
- Physical Inspection: Periodically inspect the device and its connections for any signs of damage, loose cables, or obstructions. Ensure waterproof caps are securely in place.
- Cleaning: If necessary, gently clean the exterior of the device with a soft, damp cloth. Do not use harsh chemicals or abrasive materials.
- Firmware Updates: Check the COMFAST official website regularly for firmware updates. Keeping the firmware updated ensures the latest features, security patches, and performance improvements.
- Environmental Considerations: While rated for outdoor use, avoid installing the device in locations prone to extreme physical stress or prolonged submersion.
6. Troubleshooting
6.1 No Internet Connection
- Check Cables: Ensure all Ethernet cables are securely connected to the WAN and LAN ports.
- Power Supply: Verify the device is receiving power, and the Power LED is on. If using POE, ensure the POE injector/switch is functioning correctly.
- WAN Connection: Check the status of your internet source (modem/router). Ensure the WAN LED on the CF-EW87 is active.
- Router Settings: Access the device's web interface (refer to the full installation manual for default IP and login) to check WAN settings and ensure they are correctly configured.
6.2 Slow Wi-Fi Speed or Intermittent Connection
- Signal Strength: Ensure your devices are within the optimal range of the AP. Obstacles like thick walls or metal structures can degrade signal.
- Interference: Other wireless devices or networks operating on similar frequencies can cause interference. Consider changing Wi-Fi channels in the device settings.
- Device Load: While the CF-EW87 supports many devices, excessive simultaneous high-bandwidth usage might affect performance.
- Firmware: Ensure the device firmware is up to date.
6.3 Device Unresponsive / Factory Reset
If the device becomes unresponsive or you forget the login credentials, you can perform a factory reset.
- Reset Button: Locate the RESET button on the device (often a small pinhole next to the ports).
- Procedure: With the device powered on, use a paperclip or a thin object to press and hold the RESET button for approximately 5-10 seconds until the LEDs flash. Release the button, and the device will reboot with factory default settings.
