2.2.1 Memory Installation Rules
Install memory according to the following rules.
■
Install the memory in units of eight modules.
■
All of the memory installed in a unit of eight modules must be of the same
capacity, rank, and type.
■
Within the same system, you can install memory modules of different capacities.
However, the memory installed in the DIMM slots under each CMU (CMUL or
CMUU) must be a combination of memory modules shown in Table 2-1 and Table
2-2.
■
When installing memory modules for the CMU in the SPARC M12-2/M12-2S (16
memory slots), install memory group A and then memory group B.
■
When installing memory modules of different capacities for the CMU in the
SPARC M12-2/M12-2S (24 memory slots), install memory group A, memory group
B, and memory group C in this order, from largest to smallest capacity.
■
For the SPARC M12-2S in a multiple-BB configuration, install at least one set of
memory modules (eight dual inline memory modules (DIMMs)) in each chassis.
■
To mount a 64 GB DIMM, see "Notes on Memory" in the latest version of the
Fujitsu SPARC M12 Product Notes.
