Cisco Systems 7200 VXR manual Total Dram Dram Bank Quantity Product Number

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.
