To replace the fan module in a switch, do the following:
-
Push the latching tab toward the
fan module handle and pull outward on the handle to disengage the fan module
internal connectors. See Removing a Fan Module.
-
Carefully slide the fan module
the rest of the way out of the switch.

Note
If you are not
installing a replacement fan module, install a cover over the unoccupied fan
module slot. Unoccupied slots must always be covered to maintain proper
system ventilation.
-
Verify that the airflow
direction on the replacement fan module matches that of the installed fan
modules.
Fans with front-to-back airflow are labeled Air Out.
-
Carefully slide the replacement
fan module all the way into the fan module slot, as shown in Installing a Fan Module.
-
Push the fan module in until the
latch snaps into place.

Caution
Do not slam
the fan module into the switch.
