10 Network Processing Engine Replacement Instructions
Network Processing Engine Description
Table 4 lists the NPE-100, NPE-150, and NPE-200 factory-installed DRAM configurations and their
product numbers.
Table 5 lists the NPE-175 and NPE-225 SDRAM DIMM configurations.
The NPE-300 contains two banks of SDRAM. Both SDRAM banks are used for all packet memory
requirements; however, bank 0 is used exclusively for packet memory and is set at a fixed
configuration in the factory.
Bank 1 contains two user-configurable SDRAM slots, DIMM slot 2 and DIMM slot 3 (see Figure 6).
Both slots in bank 1 can be populated by DIMMs of different sizes; however, the size of the DIMM
in slot 2 must be greater than or equal to the size of the DIMM in slot 3, and the size of the DIMM
in slot 3 can be zero.
Table 6 lists the NPE-300 factory-installed SDRAM configurations and their product numbers.
