Installing J4350 and J6350 Routers
Lift the router and insert the larger elliptical openings in the mounting brackets
onto the partially inserted screws so that the router is hanging from the two
screws (see Figure 47 on page 82).
Verify that the mounting screws on one side of the rack are aligned with the
mounting screws on the opposite side and that the router is level.
Install at least two mounting screws into each mounting bracket, in addition to
the center screws from which the router hangs (see Figure 48 on page 83). Use
a number 2 Phillips screwdriver to tighten the screws.
