Installing the CPM-a
The 7750 SR-a chassis requires a minimum of one CPM-a to operate, but two are
recommended for redundancy. CPM-a cards occupy half of a slot, as listed in Table 49.
Figure 37 shows the installation of the CPM-a in slot 4, position B of a 7750 SR-a4. Table 50
describes the installation features.
