3. Installation du processeur
- Ouvrez avec précaution le mécanisme de fixation du socket du processeur.
- Align the AMD EPYC processor with the socket, ensuring the gold triangle on the CPU matches the triangle on the socket.
- Gently place the processor into the socket without forcing it.
- Fermez le mécanisme de rétention pour sécuriser le processeur.
- Apply thermal paste and install the appropriate CPU cooler.
4. Installation de la mémoire
- Locate the 16 DDR4 DIMM slots.
- Open the retention clips on both ends of the DIMM slot.
- Alignez le module de mémoire avec l'emplacement, en veillant à ce que l'encoche du module corresponde à la languette de l'emplacement.
- Appuyez fermement sur les deux extrémités du module de mémoire jusqu'à ce que les clips de fixation s'enclenchent.
- For optimal performance, populate DIMM slots according to the motherboard's memory population guidelines (refer to the full manual for specific configurations).
5. Connexions d'alimentation
- 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.
Mode d'emploi
1. Démarrage initial
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. Configuration BIOS/UEFI
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. Installation du système d'exploitation
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.
Entretien
- Élimination de la poussière : Nettoyez régulièrement la poussière accumulée sur la carte mère et les composants de refroidissement à l'aide d'air comprimé. Assurez-vous que le système est éteint et débranché avant tout nettoyage.
- Mises à jour du micrologiciel : 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.
- Gestion des câbles: Ensure internal cables are neatly routed to promote proper airflow and prevent overheating.
Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Le système ne s’allume pas. | Power cables not connected properly; faulty power supply; faulty power button. | Check 24-pin ATX and 8-pin CPU power connections. Test power supply. Verify front panel power button connection. |
| Pas de sortie d'affichage. | Monitor not connected; faulty GPU; incorrect display output selected; memory issues. | Ensure monitor is connected and powered on. Reseat memory modules. Test with a known good GPU (if applicable). Check BIOS settings for display output. |
| Le système redémarre de manière inattendue. | Overheating; unstable power; faulty components (CPU, RAM). | Check CPU cooler installation and thermal paste. Ensure adequate case airflow. Test memory with diagnostic tools. Verify power supply stability. |
| Système d'exploitation non détecté. | Incorrect boot order; faulty storage drive; corrupted OS installation. | Check boot order in BIOS/UEFI. Verify SATA/M.2 connections. Reinstall OS if necessary. |
