Chapter 1 Product Overview
Physical Description
Note To prevent DRAM errors 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 1-3 lists the network processing engine factory-installed DRAM configurations and their product
numbers.
Use the show version command to identify the network processing engine installed in your Cisco 7204
router. The following example shows an installed NPE-150:
