System fan​

System fan

  • Supported fan types:

    • Standard fan 4056 (21000 RPM)

Note

The redundant cooling by the fans in the server enables continued operation if one rotor of a fan fails.

If there is an OCP module installed, when the system is powered off but still plugged in to AC power, system fan 1 and fan 2 will continue to spin at a much lower speed. This is the system design to provide proper cooling for the OCP module.

Electrical input​

Electrical input
One or two hot-swap power supply units for redundancy support:
