1
Turn off the system, including any attached peripherals, and
disconnect the system from its electrical outlet.
2 Open the system. See "Opening the System" on page 97.
3 Disconnect the fan's power cable from the fan-controller board.
Note the routing of the cable underneath the tabs on the chassis as you
remove them from the system. You must route these cables properly
when you replace them to prevent the cables from being pinched or
crimped.
