1. This option adds a second 64-MB DIMM for a total of 128 MB for line cards that are equipped with 64 MB.
2. Standard (default) DRAM DIMM configuration for the processor on E0, E1, or E2 line cards is 128 MB.
3. This 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.
4. A 144-pin SODIMM module is used.
5. The default memory on ISE line cards is 512-MB. This is provided as either 2 256-MB SODIMMs or 1 512-MB SODIMM.
6. 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.
Line Card Packet Memory
Line card packet memory temporarily stores data packets awaiting switching decisions by the line card
processor. Once the line card processor makes the switching decisions, the packets are propagated into
the router's switch fabric for transmission to the appropriate line card.
