ISE/Engine 3 Line Card Memory Upgrade Options

Note: Memory in SODIMM0 is not user serviceable on Engine 3 ATM line cards.'

Note: Do not mix memory sizes. Both DIMMs must be the same size memory.'

Note: upgrades to 512 MB or more require Cisco IOS Release 12.0(31)S or later, and you must upgrade the route processor ROMMON code to Version 1.13 or later before installing the upgraded memory.'

Line Card Current Configuration Memory Upgrade
Quad OC-12c/STM-4c ATM two 256 MB memory modules No memory upgrade option available
Quad OC-3c/STM-1c ATM One 512 MB memory module Upgrade to 1 GB by installing a second 512 MB memory module
Quad OC-12/STM-4 SRP N/A Does not support 1 GB memory upgrade
All other ISE Engine 3 line cards Two 128 MB memory modules Upgrade to 512 MB by installing two 256 MB memory modules
Two 256 MB memory modules Upgrade to 512 MB by installing one 512 MB memory module
Upgrade to 1 GB by installing two 512 MB memory modules
One 512 MB memory module Upgrade to 1 GB by installing a second 512 MB memory module


Route Memory Configurations for Cisco 12000 Series Line Cards

Note: The MEM-GRP/LC-64 option adds a second 64-MB DIMM for a total of 128 MB for line cards that are equipped with 64 MB.'

Note: Standard (default) DRAM DIMM configuration for the processor on E0, E1, or E2 line cards is 128 MB.'

Note: The MEM-GRP/LC-128 option allows the customer to order a spare module or add a second 128-MB DIMM for a total of 256 MB for line cards that are already equipped with one 128 MB DIMM.'

Note: The default memory on ISE line cards is 512-MB. This is provided as either 2 256-MB SODIMMs or 1 512-MB SODIMM.'

Note: The spare 512-MB SODIMM in the ATM ISE line cards can only be installed in SODIMM1. The memory in SODIMM0 is not user replaceable. '
