  • Redundant fans and hot-swappable fan modules provide high availability.
  • Regular monitoring of CPU and component temperatures is recommended. Thermal Management
  • Consider liquid cooling solutions for even more effective heat dissipation, especially in high-density deployments.

Power Requirements:

  • The server requires a dedicated power circuit with sufficient capacity to handle the peak power draw of 3200W (including both PSUs at full load).
  • Redundant PSUs provide power redundancy in case of PSU failure.
  • Uninterruptible Power Supply (UPS) is recommended to protect against power outages. UPS Systems
  • Ensure proper grounding to prevent electrical hazards.
