You can replace the route memory on Ethernet line cards. Route memory modules are installed into 144-pin small-outline DIMM (SODIMM) sockets. Route memory runs the Cisco IOS software image and stores the updated network routing tables downloaded from the route processor.

Table 20 provides information about the various hardware engines available with the Ethernet line cards. The engine determines where the memory is placed.
