Cisco 7200 VXR Installation and Configuration Guide

Chapter 1 Cisco 7200 VXR Product Overview
Field-Replaceable Units
Note To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure that 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 size SIMMs.
To determine the memory configuration of your Cisco 7200 VXR router, use the show version
command. The following example shows an NPE-G1 installed in a Cisco7206VXR router:
