DRAM
DRAM stores routing tables, protocols, and network accounting applications. The standard
RSP7000 configuration is 16 megabytes (MB) of DRAM, with up to 128 MB available through
single in-line memory module (SIMM) upgrades.
Note When upgrading DRAM, you must use SIMMs from an approved vendor. To ensure that you
obtain the most current vendor information, obtain the list from Cisco Information Online (CIO) or
the Technical Assistance Center (TAC).
