This package (MEM2600XM-128DBOT) for the Cisco 2600XM Series provides one 128-MB DIMM and the Cisco ROMmon. Two features have been introduced on all Cisco 2600XM Series multiservice routers. The first is a 128-MB synchronous dynamic RAM (SDRAM) dual in-line memory module (DIMM) for use in all new and existing Cisco 2600XM Series multiservice routers. This 128-MB DIMM offers higher-density memory, providing the ability to support memory increases to 256 MB of DRAM with the correct ROM monitor or ROMmon. All Cisco 2650XM Multiservice Router, Cisco 2651XM Multiservice Router, and Cisco 2600XM bundles and upgrades to 128 MB of DRAM now include one 128-MB SDRAM DIMM instead of two 64-MB SDRAM DIMMs. This allows for the second slot to remain open for future memory expansion up to 256 MB. The second feature is an internal ROMmon on all Cisco 2600XM Series multiservice routers. ROMmon simply provides future ability to upgrade the Cisco 2600XM Series to 256-MB DRAM. Currently the maximum memory used by Cisco IOS S...
