SPARC T7-1 Server Service Manual

Memory Riser and DIMM FRU Names

The server can contain 16 DIMMs. Eight DIMMs are installed on the motherboard. An optional eight DIMMs can be installed on two memory risers, mounted on the motherboard above the initial DIMMs. Four DIMMs are installed on each memory riser.

Labels on the transparent airflow cover identify the naming of memory risers and DIMMs.

DIMM FRU names are based on the location of the DIMM on the motherboard or on one of the two memory risers. For example, the full FRU name for the DIMM slot on the motherboard farthest from the power supplies is /SYS/MB/CM/CMP/BOB21/CH0.
