mounting bracket with a hole in each rack post, ensuring that the switch is level.

the mounting brackets to the rack posts. Tighten the screws in the two bottom holes first, and then tighten the
screws in the two top holes.
5. Check that the mounting brackets on each side of the rack are lined up with each other.
