    Rack Mounting Hole Locations for the JCS1200 Platform

    Table 1 specifies the holes in which you insert mounting screws (and cage nuts if needed) to install the mounting hardware required in a four-post or two-post 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. The bottom of all mounting shelves is at 0.04 in. (0.02 U) above a U division.
