The switch continues to operate when there is one failed fan module. If one fan
module fails, the switch sends an error message. If a second fan module fails, the
switch sends an error message, writes a failure log to flash memory, and shuts
down.
Each fan module has a green LED that is visible from the rear panel. The LED
shows the status of the fan module, as follows:
