Memory Requirements
Depending on the circumstances, you might need to determine the amount of main memory (DRAM or
SDRAM) required by your Cisco 7200 series router to support a combination of installed port adapter
types and a specific Cisco IOS software subset image.
Note
The NPE-175, NPE-225, NPE-300, and NSE-1 use SDRAM DIMMs for main memory, whereas the
NPE-100, NPE-150, and NPE-200 use DRAM SIMMs for main memory.
The NPE-400 uses a single SDRAM SODIMM for main memory.
The NPE-G1 uses two SDRAM SODIMMs for main memory.
The NPE-G2 uses a single SDRAM DIMM for main memory.
