GRP, PRP, and Line Card Memory Overview
4 GigabitEthernet/IEEE 802.3 interface(s)
DRAM DIMM Slot 1: 256M found, Slot 2: 256M found
Configuration register is 0x0
In this example, two 256-Mbyte memory modules are installed and therefore the memory is not user
upgradable.
Engine 4 Line Card Memory Locations
Figure 6 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.
Figure 6 Engine 4 Line Card Memory Locations
Note Engine 4 and Engine 4+ line cards may have a different route memory DIMM socket identifier than the
Cisco OC-192c line card shown in Figure 6. For example, the route memory module on the Cisco Quad
OC-48c line card is in the J12 socket.
Line Card Route Memory
Route memory is line card DRAM that runs the Cisco IOS software image and stores the updated
network routing tables downloaded from the GRP. Line card route memory ranges from 128 to 512 MB.
