Upgrading Memory on a Line Card

Table 7-5 lists the available configurations and associated product numbers of SDRAM DIMMs for upgrading the transmit and receive buffer memory on a line card.

Table 7-4 DRAM DIMM Configurations Available for Cisco 12000 Series Line Cards

DRAM DIMM		Memory
Sockets	DIMM Module	Provided	Product Number
P4 DIMM0	1 32-MB DIMM	32 MB	MEM-LC-321
P4 DIMM1	1 32-MB DIMM	64 MB2	MEM-LC-32=2
P4 DIMM0	1 64-MB DIMM	64 MB	MEM-GRP/LC-64=
P4 DIMM0	1 128-MB DIMM	128 MB	MEM-GRP/LC-128=
P4 DIMM0 and	2 128-MB DIMMs	256 MB	MEM-GRP/LC-256=
P4 DIMM1

1.Standard (default) DRAM DIMM configuration for the processor on a line card is 32 MB.

2.For this option, it is assumed that you already have one 32-MB DRAM DIMM installed in P4 DIMM0 and that you want to upgrade to 64 MB by adding a second 32-MB DRAM DIMM to P4 DIMM1.
