Installing Primary-Memory DRAM SIMMs
The access server 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 DRAM on the system card.
After booting up, your system will indicate in the system banner the amount of primary
memory it has. The following example shows a system with 4 MB (4,096 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 access server
is set up as a connection device between large external networks and your internal network.
