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.
