Cisco ISR 4331 3GE, 2 NIM, 1 SM, 4 GB Flash, 4 GB DRAM | Router — SP-AR1-ASR102HX

Keep branch traffic under control with the Cisco ISR 4331, a compact integrated services router designed for sites that need dependable routing, modular expansion, and practical local memory for day-to-day network services. With 3 GE interfaces, 2 NIM slots, 1 SM slot, 4 GB flash, and 4 GB DRAM, it gives infrastructure teams a balanced platform for edge connectivity without moving to a larger chassis than the site requires. This configuration is well suited to organizations that want to standardize branch routing while preserving room for service modules and future interface needs. The ISR 4331 is a strong fit when uptime, manageability, and predictable deployment matter more than chasing oversized capacity. Its modular design helps teams adapt the router to changing site requirements while keeping the footprint appropriate for branch closets and distributed offices. For procurement teams, the value is in buying only the capacity the site needs while still retaining expansion options. For network architects, it offers a practical edge platform for WAN termination, LAN aggregation, and service integration in a form factor that is easier to deploy and maintain than larger enterprise routers.
