Cisco ISR 4431 4GE 3NIM 8G Flash 4G DRAM | Enterprise Routing — CON-L14OS-SPRM5EP1

Keep critical branch traffic moving with a router designed for enterprise WAN edge requirements. Cisco ISR 4431 combines 4 Gigabit Ethernet interfaces, 3 NIM slots, 8 G flash, and 4 G DRAM to support secure connectivity, modular service expansion, and consistent performance in distributed environments. This platform is built for teams that need more than basic routing. The ISR 4431 gives you the hardware headroom to support branch services, segmentation, and operational continuity without forcing an early refresh. Its modular design helps align the platform to changing site requirements, while the onboard memory and flash support the software footprint expected in managed enterprise deployments. For infrastructure teams standardizing branch architecture, this model fits where reliability, service flexibility, and Cisco ecosystem compatibility are priorities. It is a practical choice when the cost of downtime, truck rolls, or undersized edge hardware is higher than the price of a stronger platform. Use it to anchor branch connectivity with a router sized for real enterprise workloads. Ideal For Primary WAN edge router for a medium or large branch office Modular branch deployment requiring service expansion through NIM slots Standardized Cisco routing platform across distributed enterprise sites Connectivity hub for secure branch traffic and local network services Why This Product 1 More modular than fixed-port branch routers 2 Sized for enterprise WAN edge workloads 3 Includes 3 NIM slots for service expansion 4 Provides 4 G DRAM and 8 G flash for platform headroom
