4. Configuració i instal·lació

The CF-EW85 supports both wall-mounted and pole-mounted installations. Choose the method that best suits your outdoor environment.

4.1 Instal·lació física

Instal·lació de paret

Identify a suitable location on a wall, ensuring clear line of sight for optimal signal coverage.
Use a drill to create pilot holes for the mounting screws.
Secure the AP to the wall using appropriate screws and anchors.

Pole-Mounted Installation

Select a sturdy pole in an optimal location for signal distribution.
Attach the mounting brackets to the back of the AP.
Secure the AP to the pole using the provided straps or clamps, ensuring it is firmly fixed.

4.2 Font d'alimentació

The CF-EW85 supports two power supply methods:

PoE (alimentació per Ethernet): Connect an Ethernet cable from a PoE injector or PoE-enabled switch to the WAN port of the AP. This method simplifies installation by delivering both data and power over a single cable.
Font d'alimentació de CC: Connect a 24V 1A DC power adapter (not always included, check package contents) to the DC power supply interface on the AP.

4.3 Configuració inicial

After physical installation and power connection, proceed with network configuration:

Connect a computer to one of the LAN ports of the CF-EW85 using an Ethernet cable.
Obre a web browser and enter the default IP address of the AP (refer to the Quick Installation Guide for the specific IP address, usually 192.168.1.1 or similar).
Log in using the default username and password (also found in the Quick Installation Guide).
Follow the on-screen wizard to set up your Wi-Fi network name (SSID), password, and other network parameters.

5. Instruccions de funcionament

Once the CF-EW85 is physically installed and configured, it will broadcast Wi-Fi signals for your devices to connect to.

5.1 Funcionament de doble banda

The CF-EW85 operates on both 2.4GHz and 5.8GHz frequencies. You can configure separate SSIDs for each band or use a single SSID with band steering enabled (if supported by the firmware) to allow devices to automatically connect to the optimal band.

2.4 GHz: Offers wider coverage and better penetration through obstacles, suitable for older devices or those further away.
5.8 GHz: Provides higher speeds and less interference, ideal for newer devices and bandwidth-intensive applications in closer proximity.

5.2 Centralized Management (for multiple APs)

For large-scale deployments involving multiple CF-EW85 units, they can be centrally managed using COMFAST AC management equipment. This system allows for unified control, configuration, and monitoring of all connected APs from a single interface.

6. Manteniment

6.1 Comprovacions periòdiques

Periodically inspect the physical condition of the AP, antennas, and cables for any signs of damage or wear.
Ensure all connections are secure and free from corrosion, especially in outdoor environments.
Keep the device free from excessive dust or debris, though its IP66 rating provides good protection.

6.2 actualitzacions de microprogramari

Consulta el lloc web oficial de COMFAST website regularly for firmware updates. Updating the firmware can improve performance, add new features, and enhance security. Follow the instructions provided with the firmware update package carefully.

7. Solució De Problemes

7.1 Problemes comuns i solucions

Problema	Causa possible	Solució
Small coverage area / Weak signal	Improper placement, physical obstacles, high interference.	Ensure the AP is placed in a central location with minimal obstructions. Adjust the AP power settings via the web interface to optimize signal strength. Check for sources of electromagnetic interference and relocate the AP if necessary.
Unstable internet speed / Frequent disconnections	Network congestion, interference, outdated firmware, faulty cables, incorrect configuration.	Ensure the AP is connected to a Gigabit port on your router/switch. Update the AP firmware to the latest version. Check Ethernet cables for damage and ensure they are securely connected. Utilize the 5.8GHz band for devices requiring higher stability and speed. Verify correct network settings in the AP's web interfície.
Too few concurrent users / Slow performance with many devices	Overload on the AP, insufficient upstream bandwidth, network configuration issues.	The CF-EW85 supports over 100 concurrent devices; ensure your internet connection can handle the aggregate bandwidth demand. Consider adding more APs in a centralized management setup for very high-density areas to distribute the load. Implement QoS (Quality of Service) settings if available, to prioritize critical traffic.
Installation trouble	Incorrect mounting, missing parts, unfamiliarity with process.	Refer to the "Setup and Installation" section for detailed instructions and diagrams. Ensure all mounting accessories are present and correctly used. If issues persist, consult the Quick Installation Guide or contact support.
Water ingress / Corrosion	Improper sealing of cable glands, damage to housing, exposure to extreme weather.	While the device is IP66 rated, ensure all cable glands are properly tightened to prevent water ingress during installation. Regularly inspect the housing and connections for any signs of wear or damage that could compromise the waterproof seal. Ensure the device is installed according to environmental guidelines.
El punt d'accés no s'encén	No power supply, faulty PoE injector/switch, damaged DC adapter or cable.	Verify the PoE injector/switch is providing power or the DC adapter is correctly connected and functional. Check power cables for damage and ensure they are securely connected. Try a different power source or cable if available.

8. Consells d'usuari

Col·locació òptima: For best results, mount the AP as high as possible and in a central location relative to the desired coverage area, minimizing physical obstructions like large buildings or dense foliage.
Gestió de cables: Use high-quality, outdoor-rated Ethernet cables (Cat5e or Cat6) for PoE connections to ensure reliable data and power transmission. Always ensure cable glands are properly sealed to maintain the IP66 rating.
Segmentació de la xarxa: For large networks or when providing guest access, consider creating separate VLANs to enhance security and manage bandwidth effectively, preventing unauthorized access to your main network.
Signal Strength Adjustment: If experiencing interference in dense areas or needing to fine-tune coverage, utilize the adjustable power feature in the AP's settings to optimize signal output and minimize overlap with other networks.
Seguiment periòdic: If using centralized management, regularly monitor network performance and device status to proactively address any potential issues.
