Juniper EX3300 Complete Hardware Guide

NOTE: One person must be available to lift the switch while another secures
the switch to the rack.
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. Remove the switch from the shipping carton (see “Unpacking an EX3300 Switch” on
page 82).
2. Attach the front-mounting brackets (either the flush or the 2-in.-recess brackets) to
the side mounting-rails using six 4-40 flat-head Phillips mounting screws. See
Figure 24 on page 88.

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 4x6-mm Phillips 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 25 on page 89.
