Cisco ISR 4331 Router | 3 GE, 2 NIM, 1 SM, Enterprise Branch — CON-L1NBD-10GE2348

Keep critical branch services online with the Cisco ISR 4331 platform, designed for sites that need more than basic routing. Its 3 Gigabit Ethernet ports provide core wired connectivity, while 2 NIM slots and 1 SM slot give teams the flexibility to add interfaces and services as requirements change. That modular design matters when you are standardizing across remote offices, retail locations, or distributed enterprise branches. With 4 GB flash and 4 GB DRAM, the platform is sized for routing, policy enforcement, and branch services that need consistent local performance. It is a practical fit for organizations that want to consolidate edge functions without moving to a larger chassis than the site requires. The ISR 4331 family is commonly selected where network teams need predictable deployment, manageable footprint, and Cisco integration across the branch. This configuration is well suited to environments that value serviceability and expansion headroom over low-cost commodity hardware. It gives infrastructure teams a stable foundation for branch connectivity, WAN aggregation, and future interface growth without overcommitting rack space or budget. Ideal For Primary routing for a small or midsize branch office WAN edge connectivity for distributed enterprise sites Modular interface expansion for changing branch requirements Standardized Cisco routing platform for remote locations Why This Product 1 More modular than fixed-port branch routers 2 Better suited to expanding sites than entry-level edge devices 3 Cisco platform consistency for standardized branch rollouts 4 Sized for branch routing without oversized chassis complexity
