Removing the Existing Chassis from the Rack
Before removing the existing chassis from the rack, you must shut down the system power and
disconnect the power cable and all interface cables. To help avoid problems when you install the new
chassis, label all interface cables with their slot/port address and mark the positions of the chassis
ears (with tape, chalk, or a marker) so that you can install the new chassis in the same position.
Two chassis ears hold the chassis in the rack (see Figure 3), but do not bear the weight of the chassis.
The ears are secured to the chassis sides and to the rack posts. The chassis is supported by the two
rack brackets.

the other person removes the screws that secure the ears to the rack.
