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 32 on page 85 .

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 33 on page 86 .
