6.2.7 Memory ModulesThe positions of the failing single-inline memory modules (SIMMs) are reportedby SROM power-up scripts (Section 2.2).Note• Bank 0

Warning: Memory and CPU modules have parts that operate at hightemperatures. Wait 2 minutes after power is removed before handlingthese modules.Cautio

NoteSIMMs can only be removed and installed in successive order. Forexample; to remove a SIMM at bank 0, SIMM 1, SIMMs 0 and 1 forbanks 3, 2, and 1 mu

NoteWhen installing SIMMs, make sure that the SIMMs are fully seated. Thetwo latches on each SIMM connector should lock around the edges of theSIMMs.A
