Network Processing Engine or Network Services Engine Memory Information

NPE-150 Memory Information

Note To prevent DRAM errors in the NPE-150 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 can 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.

Use the following figure and tables for information about the NPE-150 memory location, specifications,

and configurations.
