Cisco 4000 Series Overview
The Cisco 4000 series comprises the Cisco 4000-M, the Cisco 4500-M, and the Cisco 4700. 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
hardware connections. Performance is the key distinction between the Cisco 4000-M, Cisco 4500-M
and Cisco 4700.
For maximum performance in the Cisco 4000 series, the Cisco 4700 contains a 133-MHz Orion
RISC microprocessor from Integrated Device Technology, Incorporated (IDT), along with a
512 kilobyte (KB) secondary cache; the Cisco 4500-M contains a 100-MHz Orion RISC
microprocessor from IDT; and the Cisco 4000-M contains a 40-MHz Motorola 68EC030
microprocessor. The Cisco 4000 series provides flexibility, allowing network managers to easily
reconfigure the router when needs change.
