Step 1 Pinch the fan release handle, and slide the fan out.
Caution You should replace a failed fan module within 5 minutes to avoid overheating the switch.
Step 2 Insert the new fan module into the fan slot, and firmly push the module) into the slot, applying pressure
to the end of the module, not the extraction handles (
Figure 3-18). When correctly inserted, the fan
module is flush with the switch rear panel. When the fan is operating, a green LED is on in the top left
corner of the fan.
Warning
Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed
circuitry could constitute an energy hazard.
