Installing or Replacing a Fan Module
The RackSwitch G8264 contains four hot-swap fan modules. All four fan modules are required for
normal operation.
The switch continues to operate when there is one failed fan module. If one module fails, the switch
sends an error message. If a second 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 rear panel. The LED shows the status of the
fan module, as follows:
LED on: Fans are operational.
LED off: Switch unit has no power.
LED blinks: Fan speed has failed. Replace the fan module.

1.
Loosen the retainer screw.
2.
Grasp the extractor handle and gently pull the fan module from the slot.
