Location on processing engine board. See Figure 1-14. U2, U10, U14, and U26 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. Table 1-21 NPE-100 DRAM SIMM Memory Configurations Total DRAM DRAM Bank 0 Quantity DRAM Bank 1 Quantity Product Number1 32 MB U18 and U25 2 16-MB SIMMs U4 and U12 - MEM-NPE-32MB 64 MB U18 and U25 2 32-MB SIMMs U4 and U12 - MEM-NPE-64MB 128 MB U18 and U25 2 32-MB SIMMs U4 and U12 2 32-MB SIMMs MEM-NPE-128MB 1. These products are also available as DRAM upgrades. For example, to upgrade a network processing engine from 32 MB to 64 MB of DRAM, order product number MEM-NPE-64MB=. Determining Memory Configuration To determine the memory configuration of your Cisco 7200 VXR router, use the show version command.
