Cisco MEM1841-128D enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM1841-128D is a 128MB SODIMM DRAM module for the Cisco 1841 integrated services router, fitted as a memory upgrade or replacement where the router’s working memory needs to be increased beyond its base specification. 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 memory 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 not yet needing the larger 256MB module. Tech-Star supplies genuine Cisco memory spares for maintaining and upgrading established 1841 router deployments.
