Chapter 3 Mobile Access Router Card
The PCI bus connector supports communication between the Serial Mobile Interface Card (SMIC), the
Fast Ethernet Switch Mobile Interface Card (FESMIC), and the Mobile Access Router Card. The
Wireless Mobile Interface Card (WMIC) communicates with the router through an internal Fast Ethernet
port and is configured through an independent console port; the WMIC only draws power from the bus.
MARC Component Systems
The industry-standard architecture (ISA) buses and peripheral component interconnect (PCI) buses on
the Cisco 3200 Series Mobile Access Router cards provide power to the components on the cards. Both
buses comply with the PC/104-
Plus
standard. The ISA bus allows PC/104-
Plus
ISA signals to pass
through the card bus, but the Cisco cards do not use any of the signals.
Caution
If you add non-Cisco cards that generates signal on the PCI bus, the router might shut down. Please do
not add non-Cisco cards that generate signals on the PCI bus.
Figure 3-1
shows the MARC header and bus locations.

MARC Header and Bus Locations
Note
The PC/104-
Plus
standard requires that the PCI Bus and the ISA bus use keying features in the standard
stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed and the
D30 opening is plugged. On the ISA bus, pin C19 and B10 are removed, and the C19 and B10 openings
are plugged.
