Installing Primary-Memory DRAM SIMMs
The CRBRIM-W/E contains primary and shared (or packet) memory. Primary
memory size, in kilobytes (KB), is displayed in the system banner on the console
screen. Primary and shared memory are 1 MB each of the dynamic random-access
memory (DRAM) on the system board.
After booting up, your system’s primary memory is indicated in the system
banner. The following example shows a system with 1 MB (1024 KB) of primary
memory. (The system does not display shared memory.)

If you use very large routing tables or many protocols, you might need to expand
primary memory. This expansion might be necessary with configurations in which
the CRBRIM-W/E is set up as a connection device between large external
networks and your internal network.
