■ One pair each of flush or 2-in.-recess front brackets
■ One pair of side-rail brackets
■ One pair of rear brackets
■ Screws to secure the chassis and the rear brackets to the rack (not provided)
■ Dust covers for ports (for EX4200-24F switches only; optional)
CAUTION: If you are mounting multiple units on a rack, mount the heaviest unit at
the bottom of the rack and mount the other units from the bottom of the rack to the
top in decreasing order of the weight of the units.
To mount the switch on four posts in a rack:
1. Attach the front brackets (either the flush or the 2-in.-recess brackets) to the
side-rail brackets using six 4-40 flat-head Phillips mounting screws. See Figure
40 on page 122.

2. Place the switch on a flat, stable surface.
3. Align the side-rail brackets along the side panels of the switch chassis. Align the
two holes in the rear of the side-rail brackets with the two holes on the rear of
the side panel.
4. Insert 4x6-mm Phillips flat-head mounting screws into the two aligned holes and
tighten the screws. Ensure that the remaining four holes in the side-rail brackets
are aligned with the four holes in the side panel. See Figure 41 on page 123.
