10 Memory Replacement Instructions for the Network Processing Engine and Input/Output Controller
Memory Systems Overview
Table 6 I/O Controller Memory Specifications
Note To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure your system
initializes correctly at startup, DRAM bank 0 (socket U18 and U25, or U11 and U25) must contain
no fewer than two SIMMs of the same type. You may also install two SIMMs of the same type in
bank 1 (socket U4 and U12, or U42 and U52); however, bank 0 must always contain the two largest
SIMMs.
Table 7 and Table 8 list the network processing engine factory-installed DRAM configurations and
the product numbers.
Table 7 DRAMM SIMM Configurations (NPE-100, NPE-150, and NPE-200)
Table 8 lists the network processing engine factory-installed SDRAM configurations for the
NPE-175 and NPE-225. Table 9 lists the network processing engine factory-installed SDRAM
configurations for the NPE-300 and their product numbers; Table 10 lists the factory-installed Flash
memory card options and the product numbers; and Table 11 lists the Flash Disk memory options
and their product numbers.
