System fan
  • Supported fan types:

    • Standard fan (60 x 60 x 38 mm, single-rotor, 24000 RPM)

    • Performance fan (60 x 60 x 56 mm, dual-rotor, 21000 RPM)

  • Fan redundancy: N+1 redundancy, one redundant fan rotor

    • One processor: five hot-swap system fans (one redundant fan rotor)

    • One processor with middle/rear bay or Riser 3, or two processors: six hot-swap system fans (one redundant fan rotor)

Note

  • Single-rotor hot-swap fans cannot be mixed with dual-rotor hot-swap fans.

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

  • When the system is powered off but still plugged in to AC power, fans 1 and 2 may continue to spin at a much lower speed. This is the system design to provide proper cooling.

Power supplies
The server supports up to two hot-swap power supplies for redundancy.
