Cisco ISR 4321 2GE 2NIM 4G Flash 4G DRAM | Enterprise Router — CON-L1NBD-SN3795K9

Keep branch and small-office traffic under control with a router built for practical edge deployment. The Cisco ISR 4321 combines 2 Gigabit Ethernet ports, 2 NIM slots, 4 GB flash, and 4 GB DRAM in a compact platform that supports routing, service expansion, and day-to-day network operations without excess footprint. For teams that need more than basic connectivity, the modular NIM architecture matters. It gives you room to adapt the router to changing WAN or service requirements without replacing the entire platform. The onboard memory and flash support the software and operational demands of a branch edge device, while the dual GE interfaces provide the wired connectivity expected in modern distributed networks. This model is a strong fit when reliability, serviceability, and platform longevity matter more than chasing the lowest entry price. It is designed for organizations that want a router they can standardize on, expand as needs change, and keep in service across multiple deployment cycles. Ideal For Deploy as a branch office router for distributed connectivity Add modular WAN or service interfaces through NIM expansion Standardize routing across small and midsize remote sites Support edge network services where compact hardware is preferred Why This Product 1 2 GE ports support wired branch connectivity 2 2 NIM slots add modular expansion flexibility 3 4 GB flash and 4 GB DRAM support router operations 4 Better suited to standardized branch deployments than fixed-function routers
