5 Remove the screws that secure the front-panel assemblies to the chassis.
See Figure 3-50.
6 Disconnect all the cables from the backplane. See Figure 5-6 for 2.5-

remove them from the system. You must route these cables properly
when you replace them to prevent the cables from being pinched or
crimped.
