Note: Omit Steps 1, 2, and 3 if the cabinet slide sections with extenders are already
installed within the equipment rack at the proper elevation, and the chassis slide sections
are mounted on the equalizer chassis.
1. Attach chassis slide sections (Figure 2-1) to equalizer with four number 8-32
screws and lockwashers on each side of chassis.
2. Attach mounting bracket to rear of each cabinet slide section with two number
10-32 screws and flatwashers and nut plates. Before tightening hardware, adjust
mounting brackets so that mounting surfaces of brackets butt up against
mounting surfaces of equipment rack.
3. At the proper elevation within the equipment rack, mount slides with mounting
bracket to equipment rack as follows:
a. Mount each mounting bracket to rear cabinet mounting surface with
modified nut plates (optional) and two number 10-32 screws, lockwashers,
and flatwashers.
b. Mount each slide to front cabinet mounting surface with modified nut plates
and two number 10-32 screws, lockwashers, and flatwashers.
4. Slide cabinet slide extenders out to fully extended and locked positions.
5. Lift equalizer into position so that chassis slide sections are aligned with cabinet
slide extenders and slide chassis slide sections into cabinet slide extenders. Slide
equalizer back until slide release buttons on chassis slide sections snap into holes
in cabinet slide sections.
6. Connect all cables to associated rear panel connectors.
7. Press in slide release buttons, push equalizer fully into rack, and install
appropriate hardware for front panel mounting flanges to secure equalizer to
