Remove the replacement fan unit from its shipping box and carefully slide the fan into the slot
formerly occupied by the faulty unit. Connectors on the installed fan must be firmly seated in the
corresponding 8265 connectors.
Note: The fan begins rotating the moment the unit is plugged in.

Verify that the replacement fan is flush with the back of the 8265.
5
Replace the four screws that secure the fan unit to the rear of the 8265.
6
Visually inspect all installed fans to verify that each is turning without interruption.

confirm that all fan units are indeed functioning normally. LEDs for installed fans should be
illuminated to indicate normal operation.
