• 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 Probleme met netwerkverbinding

• Check that network cables are securely connected to the 2.5GbE LAN ports and your network devices (router, switch).
• Verify network configuration within your operating system.
• Ensure the network drivers are correctly installed and recognized by the operating system.

6.5 Oorverhittingsprobleme

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.
