Figure 2-7 Memory DIMM topology for the PS700
Figure 2-8 Memory DIMM topology for the PS701 and PS702 base blade
There are eight buffered DIMM slots on the PS700, and 16 on the PS701 and PS702 base
blade with an additional 16 slots on the PS702 expansion unit. The PS700 DIMM slots are
numbered P1-C1 through P1-C8 as shown in Figure 2-7. The PS701 and the PS702 base
blade have slots labelled P1-C1 through P1-C16 as shown in Figure 2-8. For the PS702
expansion unit the numbering is the same except for the reference to the second planar
board. The numbering is from P2-C1 through P2-C16.
