Replacing the SDRAM DIMM

Note The network processor card contains two SDRAM slots for user-configurable system memory, DIMM 1 and DIMM 2.

•The amount of memory installed in slot DIMM 1 must be greater than or equal to the memory installed in slot DIMM 2.

•Slot DIMM 2 is zero for the default memory configuration of 128 MB.

•Slot DIMM 0 is used only for packet memory and is fixed at 64 MB in the factory.

To replace the SRAM DIMM, do the following:
