Replacing a Rack-Mounted Chassis

Step 5 On the front of the rack, use a 1/4-inch flat-blade screwdriver to loosen and remove the four binder-head screws that secure the left and right ears to the front mounting strips on the equipment rack. (See Figure 7.) Keep the removed screws together; you will need them to secure the replacement chassis in the rack.

Warning The following step might shift the chassis’ center of gravity to the front of the rack and may cause the rack or the chassis to tip or fall. Before proceeding, ensure that you have sufficient assistance to prevent the rack from toppling and the chassis from falling out of the rack. Never attempt to lift or support the front of the chassis with the plastic front panels. The panels can break away and allow the chassis to drop.
