8. Press down on the tip insert of each standoff to lock the card in place.
9. Replace and tighten the backpanel screws to secure the SBus card to the
system board back panel.
Three SIMM options exist; two are DRAM SIMMs. (Refer to Figure 2-13.) The
third is a nonvolatile SIMM (NVSIMM). (Refer to Figure 2-14.) All three SIMM
types are removed and replaced in the same manner. Table 2-1 summarizes the
SIMM variations.

Capacity Type
8Mbyte SRAM
8Mbyte SRAM
32Mbyte SRAM
32Mbyte SRAM
1Mbyte NVSIMM (battery-backed)
Note – These SIMMs were designed for the SPARCserver 1000 system and are
not interchangeable with other types of SIMMs.
Type A 8 Mbyte SIMMs are interchangeable with Type B 8 Mbyte SIMMs. The
two 32 Mbyte SIMM types many also be interchanged. However, SIMMs of
different capacities cannot be interchanged within a group. To select the proper
socket locations for the SIMMs, refer to Appendix A, "Configuring SIMMs and
Jumpers."
