Cisco Router ISR 4000

Cisco 4000 Series Integrated Services Routers (ISR), the branch routers, is a digital-ready platform that offers at least 4 GE ports, 3 NIM slots, 2 SM slots and 8 CPU core ISM slots. It consolidates many must-have IT functions, including network, security, compute, storage, and unified communications. So you get everything you need in a single platform. The ISR 4000 Series is modular and upgradable, so you can add new services without changing equipment. It supports multiple application-aware services concurrently while maintaining WAN performance of up to 2 Gbps, even during heavy traffic loads. The backplane architecture supports high-bandwidth, module-to-module communication at speeds up to 10 Gbps.

Cisco 4000 Series ISRs are Available in These Models: the 4461 ISR, 4451 ISR, 4431 ISR, 4351 ISR, 4331 ISR, 4321 ISR and 4221 ISR.
