Install the Large Mounting Shelf in an Open-Frame Rack
Before front-mounting the router in an open-frame rack, install the large mounting shelf on the rack. The following table
specifies the holes in which you insert screws to install the mounting hardware in an open-frame rack (an X indicates a
mounting hole location). The hole distances are relative to one of the standard U divisions on the rack. For reference, the
bottom of all mounting shelves is at 0.04 in. (0.02 U) above a U division.
