For a two-postrack, Table 61 on page 232 specifies the holes in which you insert 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.
