NOTE: Each side of the chassis has twelve holes for attaching the front-mounting brackets
to the switch.
Six holes on the chassis side align with six holes in the front bracket when the front bracket
is mounted flush with the chassis front or recessed 2 in. from the front of the chassis.
3. Insert M4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws.
Ensure that the remaining four holes in the front bracket are aligned with the four holes in the side
panel. See Figure 32 on page
Figure 32: Attaching the Front-Mounting Bracket to the Switch Chassis
4. Insert M4x6-mm Phillips flat-head mounting screws into the remaining four holes in the front bracket
and tighten the screws.
5. Repeat steps 2 through 4 for attaching the front bracket to the other side of the chassis.
6. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the
front bracket 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
