Cisco ISR 4331 3GE Router | Enterprise WAN, Modular Branch — CON-L14HR-10GE2348

Keep critical branch traffic moving with a router designed for real infrastructure demands. Cisco ISR 4331 combines 3 Gigabit Ethernet ports with modular expansion through 2 NIM slots and 1 SM slot, giving teams room to adapt the edge without replacing the platform. Built for environments where routing stability matters, this ISR supports consistent WAN connectivity and the kind of hardware flexibility procurement teams value when standardizing branch deployments. The 4 GB DRAM and 4 GB flash provide the memory and storage foundation needed for router services, configuration retention, and operational continuity. This model fits organizations that need more than a basic edge device. It is suited to branch offices, distributed retail, and remote sites that depend on a router with room for interface growth and a Cisco platform that integrates cleanly into established network standards. For teams comparing entry-level routers against a platform class device, the ISR 4331 offers the expansion headroom and deployment confidence that justify the investment.
