Chapter 3 Mobile Access Router Card
MARC Power Requirements
The MARC uses +3.3-V, +5-V, and +12-V power sources. Internal on-board DC-to-DC conversion
circuitry generates 1.8 V/1.5 A from the +3.3-V power source.
MARC Router Signals
Cisco 3200 Series router cards do not support any ISA bus signals. The PCI bus connector supports
communication between Cisco 3200 Series Mobile Access Router cards.
Note
Non-Cisco MIC cards cannot use PCI signals. The use of PCI signals by non-Cisco cards causes
unpredictable results. You cannot add third-party devices that might attempt to communicate with the
SMIC through the ISA or PCI bus.
The signals are delivered through the shared, 34-pin multifunction header and the 10-pin Ethernet
header. LED signals and 5 V of power are also provided through the shared, 34-pin multifunction header.
Fast Ethernet Signals on the MARC
There is one fixed Fast Ethernet port on the MARC. A Cisco router identifies a Fast Ethernet interface
address by its slot number and port number, in the format slot/port. The slot/port address of a Fast
Ethernet interface on the MARC is 0/0.
The Fast Ethernet port signals are in compliance with IEEE 802.3. They are provided through the 10-pin
Ethernet header, which supports the following:
•
Autonegotiation and parallel detection MII interface with extended register capability for
10/100BASE-TX connection
•
Full-duplex and half-duplex modes
•
3.3-V operation low power consumption (300 mW typical)
•
Low-power sleep mode
•
10BASE-T and 100BASE-TX using a single Ethernet connection
•
Robust baseline-wander correction performance
•
100BASE-FX fiber-optic capabilities
•
Standard carrier signal multiple access collision detect (CSMA/CD) or full-duplex operation
•
Integrated, programmable LED drivers
The FastEthernet 0/0 port on the MARC is a Fast Ethernet
router
port. The FastEthernet ports on the
4-port FESMIC and the 2-port FESMIC are Fast Ethernet
switch
ports. The routing features supported
on the MARC cannot be configured on the FESMIC ports.
