Cisco ISR 4331 3GE, 2NIM, 1SM, 4G Flash, 4G DRAM | Enterprise Router — SP-AR1-C14331K9

Maintain dependable branch routing with a platform sized for real enterprise edge demands. Cisco ISR 4331 combines 3 Gigabit Ethernet ports, 2 NIM slots, 1 SM slot, 4 GB flash, and 4 GB DRAM to support routing, service expansion, and local processing in a compact footprint. It is designed for organizations that need more than basic connectivity and want a router that can handle branch services with room to grow. The value here is not just port count. The ISR 4331 is built for environments where uptime, service flexibility, and predictable branch operations matter. The modular slot layout supports add-on capabilities without forcing a full platform replacement, while the onboard memory and flash provide the resources expected in a business-class router. That makes it a strong fit for network teams standardizing on Cisco infrastructure across distributed sites. For procurement teams, this model sits in the category of infrastructure that earns its place by reducing friction at the edge. It supports branch consolidation, service segmentation, and long-term network planning with a platform that is easy to align to enterprise standards.
