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/BOB00/CH0.
Note -
DIMM names that include CH0 have black ejectors and DIMM names
that include CH1 have white ejectors.
