6. Insert the 4x6-mm Phillips flat-head mounting screws into the remaining two holes
in the side mounting-rails and tighten the screws.
7. 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 26 on page 89.
