CHAPTER

Overview of the Cisco 4000 Series Routers

The Cisco 4000 series consists of the Cisco 4000-M, the Cisco 4500-M, and the Cisco 4700-M. All models provide a configurable modular router platform using network processor modules—individual modules that when installed in the router are ready for external network connections. Performance is the key distinction between the Cisco 4000-M, Cisco 4500-M, and Cisco 4700-M.

For maximum performance in the Cisco 4000 series, the Cisco 4700-M contains a 133-MHz RISC microprocessor, 16 to 64 MB main memory, and a 512-KB secondary cache. The faster speed of the Cisco 4700-M allows higher throughput for high-speed interfaces. The 512-KB secondary cache is useful for process switching applications such as compression and encryption.

The Cisco 4500-M contains a 100-MHz RISC microprocessor and 8 to 32 MB of main memory. The Cisco 4000-M contains a 40-MHz CISC microprocessor and 4 to 32 MB of main memory.

All Cisco 4000 series routers provide flexibility, allowing network managers to easily reconfigure the router when needs change.

The Cisco 4000 series routers support up to three network processor modules at a time. The following network processor modules are available at the publication date of this guide:

• Single-port Fast Ethernet with 100BaseT and MII connectors provided for the port

• Single-port and dual-port Ethernet with 10BaseT and AUI connectors provided for each

port

• Six-port Ethernet with 10BaseT connectors provided for each port

• Dual-port and four-port synchronous serial supporting EIA/TIA-232, EIA/TIA-449,

V.35, X.21, NRZ/NRZI, DTE/DCE, or EIA-530 DTE interfaces on each port

Overview of the Cisco 4000 Series Routers 1-1

• Dual-port high-speed synchronous serial and 16-port low-speed

synchronous/asynchronous serial. The high-speed ports supports EIA/TIA-232, EIA/TIA-449, V.35, X.21, NRZ/NRZI, DTE/DCE, or EIA-530 DTE interfaces. The low-speed ports support EIA/TIA-232, V.35, or X.21 interfaces in DTE or DCE mode. Each low-speed port can be individually configured for synchronous or asynchronous.

• Single-port HSSI

• Single-port and dual-port Token Ring

• Dual attachment single-mode FDDI

• Single attachment or dual attachment multimode FDDI

• Four-port or eight-port ISDN BRI

• Four-port balanced or unbalanced G.703/G.704

• Single-port channelized T1/ISDN PRI

• Single-port balanced or unbalanced channelized E1/ISDN PRI

• Single-port ATM with single-mode OC-3 and long-reach capability, multimode OC-3,

DS-3, or E3 interfaces

Note For information about modules released after publication of this guide, see the

configuration note packet shipped with your router.

Note EIA/TIA-232 and EIA-TIA-449 were known as recommended standards RS-232

and RS-449 before their acceptance as standards by the Electronics Industries Association (EIA) and Telecommunications Industry Association (TIA)

Overview of the Cisco 4000 Series Routers 1-3

Series Specifications

Design specifications for the Cisco 4000 series are as follows:

• Modular router platform.

• Flash memory capability.

• User-upgradable network processor modules, shared memory, and processor local

memory.

• Hardware thermal alarm to warn of excessively high operating temperature.

• Can be rack-mounted in either a standard 19-inch rack or a telco rack.

• Can be mounted on a wall or placed on a desk or table.

• Support for up to three network processor modules at a time. Network processor

modules can be placed in any of the three available positions in almost any desired combination. See the Cisco Product Catalog for complete configuration details.

The BRI four-port and eight-port network interface modules can not be used in the same chassis with the channelized T1/ISDN PRI network interface module or the channelized E1/ISDN PRI network interface module.

The Cisco 4000-M does not support Fast Ethernet, HSSI, 2T16S, ATM, or six-port Ethernet network processor modules.The Cisco 4000-M can support only one FDDI network processor module in combination with any two other types of network processor modules.

The Cisco 4500-M and Cisco 4700-M can support two FDDI network processor modules. If you are only using one FDDI module, install it in the center slot for optimum heat dissipation.

The Cisco 4500-M and Cisco 4700-M can support one ATM network processor module or up to three six-port Ethernet network processor modules. The single-port Ethernet module is not supported on the Cisco 4500-M or the Cisco 4700-M.

Note The Cisco 4500-M and Cisco 4700-M support all network processor modules except

the single-port Ethernet network processor module.
