3. Install clip nuts ( 3 in Figure 3-12 on page 3-13) for vertical rack rails with
round holes or cage nuts ( 4 in Figure 3-12 on page 3-13) for vertical rack rails
with square holes in the front rack rails in the marked positions.
4. At this point you must also install clip nuts or cage nuts into the holes that will
receive the rack ears that secure each additional module to the rack. These rack
ears will only be installed on the front vertical rails. To do this, first determine
and mark the location for each of the rack ears on each of the two front vertical
rails. For each module, do the following:
a. Determine where the module will be placed. Remember that the control
module requires 5 EIAs, and each expansion module requires 9 EIAs (27
holes). Mark the EIAs for each module.
b. Each rack ear has two screws. These screws will fit into the top hole in each
of the two bottom EIAs for each module. Mark the appropriate holes for
each module.
