- Connect the USB drive to a USB port on the RS41.
- Power on the device. During startup, repeatedly press the DEL key to enter the AMI BIOS setup utility.
- In the BIOS, navigate to the boot options and set your USB drive as the primary boot device. Save changes and exit.
- Follow the on-screen instructions to install your operating system.
4. Эксплуатацыя прылады
4.1 Уключэнне/выключэнне сілкавання
- Уключэнне: Press the power button on the front panel. The device supports hardware auto power-on by default.
- Выключэнне: Perform a graceful shutdown through your operating system. Alternatively, press and hold the power button for a few seconds to force a shutdown.
4.2 Канфігурацыя сеткі
The RS41 features four 2.5GbE I226-V network ports. After installing your operating system, configure the network interfaces according to your specific network requirements (e.g., WAN, LAN, OPT interfaces for firewall setups).
4.3 Дадатковыя магчымасці
- AES-NI Support: The CPU supports AES-NI, which can be leveraged by compatible operating systems and applications for hardware-accelerated encryption/decryption, improving VPN performance.
- Network Wake-up: The device supports Wake-on-LAN (WoL) functionality. Ensure this feature is enabled in the BIOS and configured in your operating system if desired.
- System Power Management: Utilize the BIOS settings and operating system features for efficient power management.
5. Тэхнічнае абслугоўванне
The HUNSN RS41 features a fanless cooling system, which eliminates the need for fan cleaning. However, proper maintenance practices are still recommended to ensure longevity and optimal performance:
- Асяроддзе: Operate the device within the specified temperature range of 0°C to 70°C. Ensure adequate airflow around the aluminum chassis to facilitate heat dissipation. Avoid placing the device in enclosed spaces or near heat sources.
- Уборка: Keep the exterior of the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners directly on the device.
- Вільготнасць: Maintain relative humidity between 10% and 90% (non-condensing).
- Абнаўленні прашыўкі/праграмнага забеспячэння: Regularly update your operating system and any installed software to ensure security and stability.
6. Выпраўленне непаладак
If you encounter issues with your HUNSN RS41, refer to the following troubleshooting steps:
6.1 Няма харчавання / Прылада не ўключаецца
- Verify that the power adapter is securely connected to both the device's DC_IN port and a working power outlet.
- Check the power brick for any indicator lights, which typically confirm it is receiving power.
- Ensure the power button on the front panel is pressed correctly.
- If the device remains unresponsive, disconnect the power, wait 30 seconds, and reconnect.
6.2 Display Issues / No Video Output
- Ensure the monitor is correctly connected to the HDMI or DisplayPort and is powered on.
- Паспрабуйце іншы кабель дысплея або манітор, калі такі маецца.
- Access the BIOS (press DEL during boot) to check display settings.
6.3 Operating System Not Booting
- Verify that RAM modules and storage drives (M.2 SSD, 2.5-inch SATA drive) are correctly seated. Loose connections can prevent booting.
- Enter the BIOS and confirm the boot order is set correctly for your installed operating system drive.
- If recently installed, ensure the operating system installation was successful and the bootloader is properly configured for UEFI.
6.4 Праблемы з падключэннем да сеткі

- Verify network configuration within your operating system.
- Ensure the network drivers are correctly installed and recognized by the operating system.
6.5 Праблемы перагрэву
While the device is fanless, it relies on its aluminum chassis for heat dissipation. If the device feels excessively hot:
- Ensure it is placed in an area with good ventilation, away from direct sunlight or other heat sources.
- Avoid stacking other devices on top of it or placing it in an enclosed cabinet without airflow.
- Confirm that the ambient temperature is within the specified operating range.
