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 of a rack:
1. Place the switch on a flat, stable surface.
NOTE: The four-post rack-mount kit ships with the short front-mounting brackets attached
to the side mounting-rails. If you want to recess the switch in the rack, you must unscrew
the short front-mounting brackets from the side mounting-rails by using the
Phillips (+) screwdriver and attach the long front-mounting brackets to the side mounting-rails.
2. 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 panels.
3. Insert 4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws
by using the screwdriver. Ensure that the remaining four holes in the side mounting-rails are aligned
with the four holes in the side panel. See Figure 123 on page 361 .

4. Insert the 4x6-mm Phillips flat-head mounting screws into the remaining four holes in the side
mounting-rails and tighten the screws by using the screwdriver.
5. 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 the chassis is level. See
Figure 124 on page 362 .
