5. Apply thermal paste and install the appropriate CPU cooler.

4. Memory Installation

1. Locate the 16 DDR4 DIMM slots.
2. Open the retention clips on both ends of the DIMM slot.
3. Align the memory module with the slot, ensuring the notch on the module matches the key in the slot.
4. Press down firmly on both ends of the memory module until the retention clips snap into place.
5. For optimal performance, populate DIMM slots according to the motherboard's memory population guidelines (refer to the full manual for specific configurations).

5. Power Connections

• Connect the 24-pin ATX power connector from your power supply to the corresponding header on the motherboard.
• Connect the 8-pin CPU power connectors (EPS12V) to the motherboard. Ensure both are connected for dual CPU configurations.

Operating Instructions

1. Initial Boot-up

After all components are installed and connected, connect the power supply to a wall outlet and power on the system. The system should initiate POST (Power-On Self-Test) and display information on the connected monitor.

2. BIOS/UEFI Configuration

During POST, press the designated key (usually DEL or F2) to enter the BIOS/UEFI setup utility. Here you can configure boot order, system time, enable/disable integrated peripherals, and adjust performance settings. Refer to the Supermicro website for detailed BIOS/UEFI guides and firmware updates.

3. Operating System Installation

Once BIOS/UEFI is configured, proceed with the installation of your preferred operating system (e.g., Windows Server, Linux distributions). Ensure all necessary drivers for the motherboard's chipsets, LAN, and other integrated components are installed after the OS is set up.

Maintenance

• Dust Removal: Periodically clean dust from the motherboard and cooling components using compressed air. Ensure the system is powered off and unplugged before cleaning.
• Firmware Updates: Check the Supermicro support website regularly for the latest BIOS/UEFI and BMC firmware updates to ensure optimal performance, stability, and security. Follow the provided instructions carefully when performing updates.
• Cable Management: Ensure internal cables are neatly routed to promote proper airflow and prevent overheating.
