C H A P T E ROverview of the Cisco 4000 Series Routers 1-11Overview of the Cisco 4000Series RoutersThe Cisco 4000 series consists of the Cisco 4000-M, the Cisco 4500-M, and theCisco 4700-M. All models provide a configurable modular router platform using networkprocessor modules—individual modules that when installed in the router are ready forexternal network connections. Performance is the key distinction between theCisco 4000-M, Cisco 4500-M, and Cisco 4700-M.For maximum performance in the Cisco 4000 series, the Cisco 4700-M contains a133-MHz RISC microprocessor, 16 to 64 MB main memory, and a 512-KB secondarycache. The faster speed of the Cisco 4700-M allows higher throughput for high-speedinterfaces. The 512-KB secondary cache is useful for process switching applications suchas compression and encryption.The Cisco 4500-M contains a 100-MHz RISC microprocessor and 8 to 32 MB of mainmemory. The Cisco 4000-M contains a 40-MHz CISC microprocessor and 4 to 32 MB ofmain memory.All Cisco 4000 series routers provide flexibility, allowing network managers to easilyreconfigure the router when needs change.The Cisco 4000 series routers support up to three network processor modules at a time. Thefollowing 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 eachport• 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
