New Slots
Cisco 3900 series, 2900 series, and 1900 series ISRs have introduced new slots on the chassis. The first
column in Table 3 lists the new slot names. The second column lists the corresponding old slot names.
Modules previously inserted in the old slots now insert in the new slots with the help of an adapter card.
For instance, network modules (NMs), enhanced network modules (NMEs), and extension voice
modules (EVMs) use an adapter, or carrier card, to insert into the SM slot. See your router’s hardware
installation guide for adapter information.
