Cisco MEM1841-256D enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM1841-256D is a 256MB SODIMM DRAM module for the Cisco 1841 integrated services router, upgrading the router’s memory towards its maximum supported capacity of 384MB when fitted alongside the factory-installed 128MB module. The 1841 is a fixed-configuration branch-office router from the 1800 series, and additional memory is a routine requirement where the router is running IOS feature sets – security, voice or WAN optimisation services – that exceed what the base 128MB specification comfortably supports. Fitting is a standard SODIMM swap with no other chassis changes required. This is a common upgrade for small-branch 1841 deployments reaching the limits of their original memory specification. Tech-Star supplies genuine Cisco memory spares for maintaining and upgrading established 1841 router deployments.
