in the rack, then start from the bottom up or the center of the rack. The following figure shows the brackets
attached to the chassis. Depending on the bracket holes you use, the chassis may protrude in the rack
Note The cable-management brackets are attached to the chassis after you install the chassis rack-mount brackets
on the chassis and mount the chassis in the rack
