The steps correspond to the numbers shown in the front rackmount diagrams.
Secure the cable-support bar to the back end of the side brackets using two of the included screws.
Slide the KX III between the side brackets, with its rear panel facing the cable-support bar, until its front panel is flush with the “ears” of the side brackets.
Secure the KX III to the side brackets using the remaining included screws (three on each side).
Mount the entire assembly in your rack, and secure the side brackets' ears to the rack's front rails with your own screws, bolts, cage nuts, and so on.
When connecting cables to the rear panel of the KX III, drape them over the cable-support bar.
