Hot Swapping:
The fan tray can be hot swapped. The switch does not need to be powered off to replace
the fan tray. However, it needs to be done quickly before the switch shuts down (within 2
minutes).
The stacking module is not hot swappable. The switch must be powered off before installing
or replacing the module.

Replacing the Fan Tray

The fan tray is hot swappable. Replacing the fan try can be done with the switch powered on.
When a fan fails the Fan Status LED on the switch will blink simultaneously with the switch Fault
LED. In this case, the entire fan tray needs to be replaced. Individual fans cannot be replaced.
