Cisco Router Memory Kit

This kit combines a 32MB Flash SODIMM and a 128MB Main SDRAM DIMM for Cisco 851, 857, 871, 876, 877 and 878 routers. It matches the MEM870-32F and MEM870-128D part numbers in a single max memory upgrade. Network administrators use it to expand IOS image storage and runtime memory on supported branch-office platforms.

Passive Operation

The modules have no active cooling and draw power directly from the router motherboard. They add no audible noise and create no additional thermal load beyond the host chassis design. Power consumption stays within the original system budget for these memory slots.

SODIMM and DIMM Form Factors

One SODIMM and one DIMM module install into the dedicated memory sockets on each router model. The mixed form factors mean each slot accepts only its matching module, preventing mis-installation. Buyers needing higher Flash or DRAM capacities than 32MB and 128MB respectively cannot use this kit.

Questions about this item

How do I install the 32 MB flash SODIMM and 128 MB DRAM DIMM into my Cisco 871 router?

Power down the router, remove the cover, insert the flash SODIMM into the flash slot and the DRAM DIMM into the main memory slot until each clicks, then reassemble and power on.

Will the flash SODIMM or DRAM DIMM need replacement after a certain number of write cycles?

The DRAM DIMM has no wear limit; the flash SODIMM is rated for typical embedded flash endurance, so replacement is only needed if a cell fails or capacity becomes insufficient.

What is the first limitation I will hit when running the Cisco 877 at full load with this 128 MB DRAM upgrade?

The 128 MB DRAM capacity is the hard ceiling; once the running configuration and feature set exceed that amount the router cannot allocate more memory.
