3. Align the bottom holes in the mounting brackets with holes on the side panels of the switch chassis.
4. Insert mounting screws into the aligned holes. Tighten the screws.
5. Ensure that the other holes in the mounting brackets are aligned with the holes in the side panels. Insert
a screw in each hole and tighten the screws.
6. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the
mounting bracket holes with the threaded holes in the rack or cabinet rail. Align the bottom hole in
both the mounting brackets with a hole in each rack rail, making sure the chassis is level. See
