Cisco ISR 4351 Router | 3 GE, 3 NIM, 2 SM, Enterprise WAN — CON-SSSNP-C14351K9

Keep critical branch services online with the Cisco ISR 4351, a modular enterprise router designed for sites that need more than basic connectivity. Its 3 Gigabit Ethernet ports provide a solid wired foundation, while 3 NIM slots and 2 SM slots give network teams room to add interfaces and services as requirements grow. That flexibility matters when one platform must support WAN access, segmentation, and future expansion without a full refresh. Built for infrastructure teams that value consistency and control, the ISR 4351 pairs 4 GB flash with 4 GB DRAM to support router operations and configuration storage in a compact branch footprint. It is a strong fit for organizations standardizing on Cisco ISR platforms across distributed offices, retail locations, and remote sites. Compared with lower-tier routers, this model offers more expansion headroom and a better path for service growth, helping reduce replacement cycles and simplify lifecycle planning. For teams balancing performance, modularity, and long-term deployment value, the ISR 4351 delivers a practical enterprise edge platform that can adapt as the branch evolves.
