Line Card Memory

If you are upgrading or replacing line card route and packet memory, refer to the Cisco XR 12000 Series Router Memory Replacement Instructions publication for installation procedures and the most up-to-date memory options.

Ethernet Line Card Packet Memory Options

Line card packet memory temporarily stores data packets awaiting switching decisions by the line card processor. Once the line card processor makes the switching decisions, the packets are propagated into the router switch fabric for transmission to the appropriate line card.

Table 22 lists the packet memory options for Ethernet line cards.

1.The SDRAM DIMMs installed in a given buffer (either receive or transmit) must be the same type and size, but the individual receive and transmit buffers can operate with different memory capacities.

Removing and Installing Line Card Memory

Before beginning the memory replacement procedures in this section, ensure that you have the proper tools and equipment at hand, and that you are using appropriate ESD-prevention equipment and techniques. Before removing or installing memory, observe the following guidelines:

•Route memory DIMMs

–Route memory DIMM0 socket must always be populated.

–For certain memory configurations, the route memory DIMM1 socket can remain empty.

–DIMMs must be 3.3V devices.

•Packet memory DIMMs

–All four DIMM sockets for SDRAM buffer memory must be populated.

–Both DIMM sockets for a given buffer pair (either those for the transmit buffer or those for the receive buffer) must be populated with SDRAM DIMMs of the same type and size.

–Size of the DIMMs in the transmit buffer need not match the size of the SDRAM DIMMs in the receive buffer.

–DIMMs must be 3.3V devices.

Instructions are in the following sections:
