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

1-2 Cisco 4000 Series Installation Guide
•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)

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.

Memory Systems
Table 1-3 Cisco 4000 Series Processor and Memory Specifications
Memory Systems
The Cisco 4000 series memory systems (see Figure 1-2) have the following functions:
•Main memory—Stores the running configuration and routing tables. The Cisco IOS
software executes from main memory.
•Shared memory—Used for packet buffering by the router’s network interfaces.
•Flash memory—Stores the operating system software image. In the Cisco 4500-M and
4700-M, the Flash memory also stores the boot helper software.
•NVRAM—Stores the system configuration file and the virtual configuration register.
•Boot EPROM—In the Cisco 4000-M, erasable programmable read-only memory
(EPROM)-based memory stores the boot helper—a subset of the Cisco IOS
software—and the ROM monitor. In the Cisco 4500-M and Cisco 4700-M, only the
ROM monitor is EPROM based. The boot helper image allows you to boot the router

when Flash memory does not contain a valid system image. In the Cisco 4500-M and
4700-M, the ROM monitor allows you to boot a system image from Flash memory if a
boot helper image is not present in boot Flash memory.
The differences between the memory systems in the Cisco 4000 series allows enhanced
software upgradability in the Cisco 4500-M and Cisco 4700-M.
