Finding the Fan Module Serial Number
Step 2 Install the fan module in the fan slot, and firmly push it into the slot, applying pressure to the end of the
module, not the extraction handles. 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. See Figure 5-2.
Warning
Do not reach into a vacant slot when installing or removing a module. Exposed circuitry is an energy
hazard.
