5. Setup Guide
As a barebone system, the SJRC X86 P6 Mini PC requires the installation of RAM, an SSD, and an operating system before first use.
5.1 Installing RAM and SSD
- Prepare the Device: Ensure the Mini PC is powered off and disconnected from all power sources.
- Open the Chassis: Carefully remove the screws securing the bottom panel of the Mini PC. Gently lift the panel to expose the motherboard.
- Install RAM: Locate the DDR5 SODIMM slot (refer to Figure 4.3). Align your DDR5 SODIMM module with the slot, ensuring the notch on the module matches the key in the slot. Insert the module at a 45-degree angle and press down firmly until the retaining clips snap into place.
- Install M.2 NVMe SSD: Locate the M.2 2280 NVMe slot. Insert your M.2 SSD into the slot at a slight angle. Once fully seated, gently push down the end of the SSD and secure it with the provided screw.
- Install 2.5-inch SATA Drive (Optional): If using a 2.5-inch SATA drive, connect it to the 12-pin SATA slots (non-standard, refer to motherboard layout for specific connection points) and secure it within the chassis if mounting points are available.
- Close the Chassis: Carefully replace the bottom panel and secure it with the screws.
5.2 Initial Connections
- Connect Display: Connect your monitor(s) to the HD 2.0 ports on the front panel (refer to Figure 4.1). The device supports dual 4K@60Hz displays.
- Connect Peripherals: Connect your keyboard, mouse, and other USB devices to the available USB 3.2 or USB 2.0 ports.
- Connect Network (Optional): For wired network access, connect an Ethernet cable from your router/modem to one of the 2.5GbE LAN ports (ETH0 or ETH1) on the rear panel (refer to Figure 4.1).
- Connect Power: Connect the power adapter to the DC-12V input port on the rear panel, then plug the power cord into an electrical outlet.
6. Operating Instructions
6.1 Powering On/Off
- Power On: Press the power button located on the front panel (refer to Figure 4.1). The power indicator light will illuminate.
- Power Off:
- Software Shutdown: For safe shutdown, always use the operating system's shutdown function.
- Hard Shutdown: In case of system unresponsiveness, press and hold the power button for approximately 5-7 seconds until the device powers off. Use this method only when necessary to prevent data loss.
6.2 Operating System Installation
The SJRC X86 P6 Mini PC supports various operating systems. You will need to create a bootable USB drive with your preferred OS installer.
- Prepare Bootable Media: Create a bootable USB drive with your chosen operating system (e.g., Windows 10/11, Linux distributions like Ubuntu, Debian, CentOS, or specialized OS like Open-wrt, PF-sense, OPNsense). Ensure the USB drive is formatted correctly for UEFI boot.
- Access BIOS/UEFI: Power on the Mini PC and repeatedly press the DEL or F2 key (common keys, may vary slightly) to enter the BIOS/UEFI setup utility.
- Configure Boot Order: Navigate to the "Boot" or "Boot Options" section in the BIOS/UEFI. Set your bootable USB drive as the primary boot device. Save changes and exit the BIOS/UEFI.
- Install OS: The Mini PC will now boot from your USB drive, and you can proceed with the operating system installation as per the OS's instructions.
6.3 BIOS Features
The BIOS/UEFI offers several advanced features:
- PXE Boot: Allows the Mini PC to boot from a network server.
- Wake-on-LAN (WoL): Enables the device to be powered on remotely via a network signal.

7. Maintenance
The SJRC X86 P6 Mini PC features a fanless design, which significantly reduces maintenance requirements related to dust accumulation in fans. However, proper care is still essential for optimal performance and longevity.
- Keep Clean: Regularly wipe the exterior of the Mini PC with a soft, dry cloth to remove dust. Avoid using liquid cleaners directly on the device.
- Ensure Airflow: Although fanless, the aluminum housing acts as a heatsink. Ensure the device is placed in a location with adequate air circulation to allow for proper heat dissipation. Do not obstruct the cooling fins.
- Operating Environment: Operate the Mini PC within its specified temperature range of -0°C to +70°C and humidity range of 5%-90% (non-condensing). Avoid extreme temperatures or high humidity environments.
- Software Updates: Keep your operating system and drivers updated to ensure system stability and security.
