Figure 62: Installing the Mounting Hardware for an Open-Frame Rack

Table 88 on page 164 specifies the mounting holes in which you insert the mounting screws
(an X indicates a mounting hole location), and cage nuts if needed. 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.
