The steps correspond to the numbers shown in the rear rackmount diagrams.
Secure the cable-support bar to the front end of the side brackets, near the side brackets' “ears,” 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 back edges 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 user station or switch, drape them over the cable-support bar.
