The memory configuration is adjustable to the application’s needs via se-
lection of the appropriate memory modules. The memory configuration
must fulfill the following requirements:
• The lowest memory module (#1) must be a SPARC/MEM-50L –
which is a lower memory module.
• The top memory module (with the greatest number in your configura-
tion given the number scheme in the figure above) can be a
SPARC/MEM-50M or SPARC/MEM-50U – which is a middle (M)
or upper (U) memory module. The upper module misses the connec-
tors for another memory module to be stacked on top.
• The memory modules between the lowest and the top memory module
must be SPARC/MEM-50M, i.e. middle memory modules.
• If a UPA64S card is installed, at most 2 memory modules can be
installed and memory module #2 must be a SPARC/MEM-50U, i.e.
an upper memory module.
• Note the limitations given by the SPARC/CPCI-52x(G) configuration
under consideration (see section 4.2 “Mechanical Construction” on
page 23).
Out of the extensive list of possible configurations the following memory
module configurations have been qualified (others may be tested and
qualified on request):
For installation information see the respective Installation Guide deliv-
ered together with the memory module.
3.1.3 Solaris Installation
When installing Solaris, there are some general installation guidelines to
be followed before and during Solaris installation and a specific guideline
related to SCSI to be followed after Solaris installation (see “SCSI” on
page 20).
