NUMAlink Cabling for a Silicon Graphics Prism
If your system was shipped from SGI with the modules already mounted in a rack and
the NUMAlink cables pre installed, you should proceed to “Optional SGI ImageSync
Cabling” on page 16 to continue.
This section describes the NUMAlink cabling for the basic configuration. For additional
NUMAlink cabling information, see “System Configurations” on page 60.
Figure 1-10 shows a system with a base compute module and one XG2N graphics
module.
