Cisco MEM2851-512D enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM2851-512D is a 512MB DDR DIMM memory module for the Cisco 2851 integrated services router, fitted where the router’s working memory needs to be increased to run demanding IOS feature sets. The 2851 is the higher-capacity end of the fixed-configuration 2800 series, typically deployed at larger branch or regional-office sites running combined routing, security, voice and WAN services together, and its higher memory ceiling reflects that heavier workload compared with the smaller 2801/2811/2821 models in the same series. Fitting is a standard DIMM swap with no other chassis changes required. This is a common upgrade for 2851 deployments running the fuller range of the platform’s IOS feature set. Tech-Star supplies genuine Cisco memory spares for maintaining and upgrading established 2851 router deployments.
