    Overview

    Cisco MEM-2951-512U1GB Overview

    The Cisco MEM-2951-512U1GB is a dedicated router DRAM upgrade for the Cisco 2951 ISR, targeting branch and mid-sized enterprise networks that require higher performance and feature headroom. This 1GB DDR2 SDRAM DIMM doubles the original 512MB DRAM to 1GB, enabling more simultaneous services, larger routing tables, and additional security or voice features. With ECC support, 800MHz speed, and enterprise-grade 0–85°C operating range, it delivers reliable, stable memory expansion for business-critical deployments.

    Product Applications Scenarios

    Enterprise Network
    Upgrading Cisco 2951 ISR memory to 1GB boosts routing scale and services, helping enterprises run more VPN, voice, and security workloads without adding extra hardware cost.
    Cloud Services
    Expanded DRAM on Cisco 2951 ISR improves stability for hybrid-cloud access, handling more tunnels and policies while keeping latency low for regional cloud connections.
    Edge & IoT
    With 1GB DRAM, Cisco 2951 ISR can process more edge data, routing rules, and security functions at branch or IoT aggregation sites, reducing CPU contention and reboots.
