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.

3200 specifications

Cisco Systems 3200 Series routers are designed to deliver high-performance, reliable networking solutions for enterprise and service provider environments. They are part of Cisco's extensive portfolio that addresses the challenges of modern networking, particularly in connecting remote offices and branch locations efficiently and securely.

One of the standout features of the Cisco 3200 Series is its scalability. The routers support a variety of modular interfaces, allowing organizations to tailor their network infrastructure according to specific needs. This modularity ensures that as businesses grow and their networking requirements evolve, the Cisco 3200 can adapt without necessitating a complete overhaul of existing hardware.

Security is another critical characteristic of the Cisco 3200 routers. They incorporate robust security features such as integrated firewall capabilities, advanced encryption standards, and Virtual Private Network (VPN) support. This ensures that sensitive data transmitted over the network is protected from potential threats, making them ideal for businesses that prioritize security, especially in regulated industries.

Performance-wise, the Cisco 3200 is equipped with advanced processing capabilities, enabling it to handle high data throughput even in demanding environments. This performance is bolstered by the use of Cisco's proprietary technologies, such as Quality of Service (QoS) and traffic shaping, which allow the prioritization of critical applications to ensure seamless connectivity.

The router series also benefits from Cisco's extensive software ecosystem, which includes Cisco IOS (Internetwork Operating System). IOS provides a familiar interface for network administrators, alongside a wealth of features for configuration and management. Furthermore, the Cisco 3200 Series is designed to integrate with Cisco's Application Policy Infrastructure Controller (APIC) and Software-Defined Networking (SDN) solutions, offering enhanced flexibility in managing network resources.

Connectivity options for the Cisco 3200 Series are extensive, offering support for various WAN technologies, including MPLS, LTE, and broadband internet. This versatility enables organizations to choose the best connectivity solutions according to their geographic and operational requirements.

Finally, the Cisco 3200 Series routers are built with reliability in mind. They are designed for high availability and redundancy, ensuring that network services remain uninterrupted in the event of hardware failures or maintenance activities.

In conclusion, Cisco Systems 3200 routers represent a comprehensive networking solution, combining scalability, security, performance, and reliability, making them a preferred choice for organizations looking to enhance their networking infrastructure in a dynamic digital landscape.
