Product Overview
All the Cisco 2900 Series base platforms ship with a default memory of 512-MB DRAM and 256-MB Compact Flash. The default Cisco 2951 has a unique memory configuration, whereby a 512-MB DIMM is installed in one of the two memory slots on the router. Memory upgrades on the Cisco 2951 can involve an increase in the density of that single DIMM or a combination of DIMMs with both slots populated. The Cisco 2951 allows the use of asymmetric densities of DRAM in both slots. On the Cisco 2921, 2911, and 2901, the default DRAM of 512 MB is soldered onto the motherboard. Hence, memory upgrades will populate the remaining memory slot in densities of 512 MB, 1 GB, and 2 GB. DRAM part numbers are shared across the Cisco 2921, 2911, and 2901, and you cannot use them on a Cisco 2951. Likewise, you cannot use the Cisco 2951 DRAM memory on other Cisco 2900 Series platforms. Table 8 gives DRAM information about the Cisco 2900 Series routers.Table 8. Cisco 2900 Series Routers DRAM (Factory Upgrades and Spares)
