Reviewing Core/Net module placement
Core/Net modules are installed side-by-side on top of separate pedestals, for
power and cooling redundancy. Core/Net 1 is always on the left. Core/Net 0
is always on the right (see Figure 87 on page 211).
Reviewing required Core cards
All Core cards are installed in the factory. See Table 26 on page 210 for the
Core card requirements for each Core/Net module. Refer to “System
equipment – UEMs” on page 38 for module and card descriptions.

system depends on the number of Network groups installed in the system. See the System
Layout plan to determine the number and placement of cCNI cards.
