5. Setup Guide
5.1. Site Preparation
- Location: Choose a central location for optimal Wi-Fi coverage, away from obstructions and sources of interference (e.g., microwave ovens, cordless phones).
- Power: Ensure a suitable power source is available (PoE+ or 12V DC adapter).
- Network Connectivity: Plan for Ethernet cable routing to your network switch or router.
5.2. Mounting the Access Point
The AP-655 can be mounted on a ceiling or wall. Use the provided mounting bracket and hardware.
- Attach the mounting bracket to the desired surface using appropriate screws.
- Align the AP-655 with the bracket and twist to lock it into place.
5.3. Connecting the Access Point
- Connect an Ethernet cable from your network switch (with PoE+ support) to one of the 5 Gbps Ethernet ports (E0 or E1) on the AP-655.
- Alternatively, if not using PoE+, connect a 12V DC power adapter (sold separately) to the power input port.
- The system LED (Sys) will illuminate to indicate power and operational status.
5.4. Initial Configuration
Initial configuration is typically performed via a network controller (e.g., Aruba Central, Mobility Conductor) or through a local console connection. Refer to the Aruba documentation for detailed software configuration steps.
6. Operating Instructions
6.1. LED Indicators
The AP-655 features several LED indicators to provide status information:
- Sys LED: Indicates system status (e.g., booting, operational, error).
- 2GHz LED: Indicates activity on the 2.4 GHz radio band.
- 5GHz LED: Indicates activity on the 5 GHz radio band.
- 6GHz LED: Indicates activity on the 6 GHz radio band.
Refer to the Aruba documentation for specific LED behavior and troubleshooting codes.
6.2. Network Operation
Once configured, the AP-655 will broadcast Wi-Fi networks (SSIDs) on the 2.4 GHz, 5 GHz, and 6 GHz bands. Client devices can connect to these networks using standard Wi-Fi protocols. The AP-655 intelligently manages client connections across the available bands for optimal performance.
7. Maintenance
7.1. Cleaning
To maintain optimal performance, periodically clean the exterior of the access point with a soft, dry cloth. Do not use liquid cleaners or aerosol sprays.
7.2. Firmware Updates
Regularly check for and apply firmware updates provided by Hewlett Packard Enterprise (Aruba). Firmware updates often include performance enhancements, security patches, and new features. These updates are typically managed through your Aruba network controller.
7.3. Environmental Considerations
Ensure the access point is operated within its specified environmental conditions (temperature, humidity) to prevent damage and ensure longevity.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power / Sys LED off | No power from PoE+ switch or power adapter; faulty cable. | Verify PoE+ is enabled on the switch port or check power adapter connection. Test with a different Ethernet cable or power source. |
| Poor Wi-Fi signal or slow speeds | Interference; AP placement; too many clients; outdated firmware. | Relocate AP away from interference sources. Ensure optimal placement. Check client count. Update firmware. |
| Clients cannot connect to Wi-Fi | Incorrect Wi-Fi settings (SSID, password); AP not broadcasting. | Verify SSID and password. Check AP configuration via controller. Ensure AP is operational (Sys LED). |
| 6GHz band not visible | Client device does not support Wi-Fi 6E; 6GHz radio disabled. | Ensure client device is Wi-Fi 6E compatible. Verify 6GHz radio is enabled in AP configuration. |
