Cisco ISR 4431 4GE 3NIM 8G Flash 4G DRAM IPB | Enterprise Router — CON-L14HR-C1S443K9

Maintain dependable branch performance with Cisco ISR 4431, a router designed for organizations that need more than basic connectivity. Its 4 Gigabit Ethernet interfaces provide a solid network foundation, while 3 NIM slots give teams room to add the services and interfaces required by changing site demands. With 8 GB flash and 4 GB DRAM, the platform is sized to support routing workloads and operational consistency in environments where downtime is expensive. This model fits well in distributed enterprise networks where the WAN edge must handle traffic growth, policy enforcement, and future expansion without forcing a full platform replacement. The ISR 4431 is a practical choice when procurement teams need a Cisco branch router with enough capacity to justify the investment and enough modularity to extend its service life. It is built for infrastructure teams that value predictable operation, upgrade flexibility, and a clean path for scaling branch capabilities over time. Ideal For Branch office WAN edge routing Distributed enterprise network aggregation Sites requiring modular interface expansion Routing platforms for secure branch connectivity Why This Product 1 More expansion headroom than fixed-port branch routers 2 Better suited for evolving sites than entry-level ISR models 3 Cisco platform depth supports long-term branch standardization 4 Modular design helps avoid premature hardware replacement
