Fan mode behavior

In non-redundant fan mode, a fan failure or a missing fan causes:

• The system Health LED to flash amber.

• The operating system to orderly shut down.

In redundant fan mode:

• A fan failure or a missing fan will switch the system to non-redundant fan mode.

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

• A second fan failure or a missing fan causes the operating system to orderly shut down.
