To mount the switch on four posts of a rack:
1. Remove the switch from the shipping carton (see “Unpacking an EX2300 Switch” on
page 123).
2. Attach the front-mounting brackets (either the flush or the 2-in.-recess brackets) to
the side mounting-rails by using 6 Phillips 4-40 flat-head mounting screws. See
Figure 38 on page 139.

3. Place the switch on a flat, stable surface.
4. Align the side mounting-rails along the side panels of the switch chassis. Align the
two holes in the rear of the side mounting-rails with the two holes on the rear of the
side panel.
5. Insert the Phillips 4x6-mm flat-head mounting screws into the two aligned holes and
tighten the screws. Ensure that the two holes in the rear of the side mounting-rails
are aligned with the remaining two holes in the side panel. See Figure 39 on page 139.
6. Insert the Phillips 4x6-mm flat-head mounting screws into the remaining two holes
in the side mounting-rails and tighten the screws.
7. Have one person grasp both sides of the switch, lift the switch, and position it in the
rack, aligning the side mounting-rail holes with the threaded holes in the front post
of the rack. Align the bottom hole in both the front-mounting brackets with a hole in
each rack rail, making sure that the chassis is level. See Figure 40 on page 140.
