Engine 4 Line Card Memory Locations

Figure 47 shows the DIMM socket locations on an Engine 4 line card. These line cards are equipped with five DIMM sockets:

•One route memory small-outline DIMM (SODIMM) socket

•Two pairs of packet memory DIMM sockets (not user serviceable)

The route memory module is installed to a 144-pin SODIMM socket. Route memory runs the Cisco IOS software image and stores the updated network routing tables downloaded from the route processor.

Ethernet Line Card Route Memory Options

Route memory runs the Cisco IOS software image and stores updated network routing tables downloaded from the route processor (RP). Line card route memory ranges from 128 MB to 256 MB. Table 21 lists the available route memory configurations and associated product numbers of the memory modules used for upgrading route memory on Ethernet line cards.

Table 21 Route Memory Configurations for Ethernet Line Cards

Total Route Memory	Cisco Product Number	DIMM Module	Route Memory DIMM Sockets
64 MB	MEM-GRP/LC-64=1	1 64-MB DIMM	DIMM0 or DIMM1
128 MB	MEM-DFT-GRP/LC-128	1 128-MB DIMM	DIMM0 or DIMM1
128 MB	MEM-GRP/LC-128=	1 128-MB DIMM	DIMM0 or DIMM1
256 MB	MEM-GRP/LC-256=	2 128-MB DIMMs	DIMM0 and DIMM1
256 MB	MEM-LC4-256=2	1 256-MB SODIMM	Varies

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.This option is only compatible with the 4-Port Ethernet line cards and is for replacement only.
