Cisco MEM-NP16M-M enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM-NP16M-M is a 16MB DRAM SIMM memory upgrade module for Cisco’s modular router platforms of the mid-1990s to early-2000s generation. Adding SIMM-based DRAM increases the amount of working memory available to the router’s IOS image, routing tables and buffer allocation, which matters on older platforms with modest onboard memory as feature sets and network scale grew.

SIMM memory of this type was the standard upgrade path before Cisco moved later platforms to DIMM-based memory, and it remains the correct spare for restoring or upgrading capacity on routers still running that generation of hardware. Genuine memory is important here because a mismatched or faulty SIMM can prevent a router from booting at all. Tech-Star is UK-based, ships worldwide and can confirm exact compatibility with your specific router platform on request.
