2.2 Component Installation (RAM & Storage)
This is a barebone system, requiring the installation of RAM and storage devices. Ensure the device is powered off and disconnected from the power source before proceeding.
- Accessing the Interior: Unscrew the bottom panel of the Mini PC to expose the motherboard.
- RAM Installation: Locate the two DDR4 SO-DIMM slots. Gently insert the RAM modules into the slots, ensuring they are correctly oriented and firmly seated until the side clips lock them into place.
- M.2 SSD Installation: Identify the M.2 slots on the motherboard. Insert the M.2 SSD at an angle, then push it down and secure it with the provided screw.
- 2.5-inch SATA SSD/HDD Installation: If installing a 2.5-inch drive, connect it to the SATA data and power connectors (cables may be included or purchased separately). Secure the drive within the designated bay. Note that the internal fan may need to be removed to accommodate two 2.5-inch drives.
- Reassembly: Carefully replace the bottom panel and secure it with screws.
2.3 External Connections
Connect peripherals and network cables to the appropriate ports.
- Power: Connect the power adapter to the DC 12V input port.
- Display: Connect a monitor to the VGA port.
- USB Devices: Connect keyboards, mice, or other USB devices to the available USB 2.0 and USB 3.0 ports.
- Network: Connect Ethernet cables to the 2.5G LAN ports (Intel i226V B3). For high-speed networking, insert SFP+ modules into the 10G SFP+ ports and SFP modules into the 1G SFP ports.
- Console: The console port can be used for serial communication for system configuration.
3. Operating Instructions
3.1 Powering On/Off
- Power On: Press the power button located on the front panel.
- Power Off: Perform a proper shutdown through your operating system. Alternatively, press and hold the power button for 5 seconds to force a shutdown.
3.2 BIOS Configuration
To access the BIOS setup, press the DEL or F2 key repeatedly during startup. Important BIOS settings include:
- Boot Order: Configure the boot sequence for your operating system installation media.
- State After G3: To enable automatic power-on after AC power is restored, navigate to IntelRCSetup > South Bridge Chipset Configuration > State After G3 and set it to 'Power On'.
3.3 Operating System Installation
The unit comes with an inactive Windows 10 for initial testing. It is recommended to re-install your preferred operating system (e.g., pfSense, OPNsense, Linux distributions, or a licensed Windows version) for optimal performance and security. Ensure you have the necessary drivers for the Intel i226V LAN ports, as some operating systems may require manual driver installation.
4. Maintenance
4.1 Cleaning
Regularly clean the exterior of the Mini PC with a soft, dry cloth. Avoid using liquid cleaners directly on the device. For internal cleaning, especially if the optional fan is installed, use compressed air to remove dust from vents and components. Ensure the device is powered off and unplugged before cleaning.
4.2 Fan Management
The S20 Mini PC features a fan-less design for silent operation, relying on its aluminum alloy case for heat dissipation. A small internal fan is included by default to enhance cooling, potentially lowering temperatures by approximately 10 degrees Celsius. This fan is removable if not desired or if additional space is needed for storage devices.
5. Troubleshooting
This section addresses common issues you might encounter.
- No Power:
- Ensure the power adapter is securely connected to both the Mini PC and a working power outlet.
