The HUNSN RJ05f supports various operating systems, including FreeBSD kernel-based router systems (version 5.10.x and above), Linux distributions, and Windows OS. It supports UEFI boot only.

1. Prepare a bootable USB drive with your chosen operating system.
2. Insert the bootable USB drive into a USB port on the appliance.
3. Power on the device. You may need to press a specific key (e.g., DEL, F2, F10, F12) during startup to enter the BIOS/UEFI settings or boot menu to select your USB drive as the boot device.
4. Follow the on-screen instructions to install the operating system.

5. Operating Instructions

5.1. Power On/Off

• To Power On: Press the power button on the front panel.
• To Power Off: Perform a graceful shutdown through your operating system. Alternatively, press and hold the power button for 5 seconds for a forced shutdown (not recommended for regular use).

5.2. Advanced Features

• Hardware Auto-Power-On: The device supports automatic power-on after a power outage. This feature is enabled by default.
• Wake-on-LAN (WoL): The appliance supports Wake-on-LAN, allowing you to remotely power on the device over the network. This feature may need to be enabled in the BIOS/UEFI settings.
• System Power Management: Utilize your operating system's power management features for optimal energy efficiency.
• Temperature Management: The fanless design ensures silent operation and efficient heat dissipation. Monitor system temperatures through your operating system if necessary.

6. Maintenance

The HUNSN RJ05f is designed for low maintenance due to its fanless construction.

• Cleaning: Periodically wipe the exterior of the appliance with a soft, dry cloth to remove dust. Avoid using liquid cleaners directly on the device.
• Ventilation: Ensure the appliance is placed in a location with adequate airflow to prevent heat buildup, despite its fanless design. Do not block the ventilation fins.
• Environmental Conditions: Operate the device within the specified temperature and humidity ranges to ensure longevity and stable performance.

7. Troubleshooting

If you encounter issues with your HUNSN RJ05f, consider the following troubleshooting steps:

• No Power:
  • Ensure the power adapter is securely connected to both the appliance and a working electrical outlet.
  • Verify the power cord is properly connected to the adapter.
  • Test the outlet with another device.
• No Display Output:
  • Check that the monitor is properly connected to either the DP or HDMI port and is powered on.
  • Ensure the monitor input source is correctly selected.
  • Verify that RAM and storage are correctly installed, as a barebone system will not boot without them.
• Operating System Not Booting:
  • Confirm that the RAM and storage devices are correctly installed and detected in the BIOS/UEFI.
  • Ensure your operating system installation media is bootable and correctly selected in the boot menu.
  • Verify that the OS image is compatible with UEFI boot.
  • Check for any error messages during boot.
• Network Connectivity Issues:
  • Ensure network cables are securely connected to the LAN ports.
  • Verify network driver installation within your operating system.
  • Check your firewall/router software configuration for proper network interface setup.
• System Instability/Freezes:
  • Ensure RAM modules are properly seated.
  • Check for overheating (though unlikely with fanless design, ensure proper ventilation).
  • Verify OS and driver integrity.
