Cisco MEM-4400-8G enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM-4400-8G is an 8GB DRAM upgrade kit (supplied as two 4GB modules) for the Cisco ISR 4400 Series Integrated Services Routers, listed by Cisco as a spare memory option for this router family. The ISR 4400 series ships with a base memory configuration that can be a limiting factor once a router is loaded with multiple services (routing, security, WAN optimisation and voice functions running concurrently on the same platform), and this 8GB kit is one of Cisco’s supported upgrade paths for increasing that headroom without replacing the router itself. As a genuine Cisco-specified memory kit it is built to the router’s supported timing and capacity specification, avoiding the compatibility and stability issues that unverified third-party memory can introduce on a platform running multiple concurrent services. ISR 4400 routers remain in widespread service as branch and edge routing platforms, and memory upgrades of this kind are a common, low-disruption way to extend a router’s useful service life as its workload grows. Tech-Star (UK-based, shipped worldwide) stocks Cisco ISR memory upgrades for ongoing router estate maintenance.
