Fan mode behavior

In nonredundant fan mode, a fan failure or a missing fan causes:

• The system Health LED to flash amber.

• The operating system to orderly shutdown.

In redundant fan mode:

• A fan rotor failure will switch the system to nonredundant fan mode.

  This change is indicated by the Health LED flashing amber. The system continues to operate normally in this mode.

• A second fan rotor failure or a missing fan causes the operating system to orderly shutdown.
