Field-Replaceable Units
To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure that your system
Note
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.
