Connections Through Crossbar Boxes (With An Expansion Rack) - Fujitsu M10 Installation Manual

Note - The SPARC M10 systems have Oracle Solaris preinstalled. According to the purpose,
either use the preinstalled Oracle Solaris as is or reinstall it.
To reinstall Oracle Solaris, install the latest Oracle VM Server for SPARC. For the latest
information on the supported Oracle Solaris versions and SRU, see the Fujitsu M10/SPARC
M10 Systems Product Notes.
Connections through crossbar boxes (with an
expansion rack)
The crossbar box is used for a logical connection between a CPU and the SPARC
M10-4S. The crossbar box is mounted in an expansion rack.
The configuration of connections through crossbar boxes connects each SPARC
M10-4S unit by crossbar cables (optical) and XSCF cables through the crossbar boxes.
It can be expanded to up to the 16BB configuration.
In addition to the crossbar boxes, dedicated power distribution units for supplying
power, crossbar cables (optical), and XSCF cables are mounted in the expansion rack.
This section describes the flow from installation of a building block configuration to
the initial system settings.
The initial system settings are the settings implemented before system startup, and
they include the XSCF setup, CPU Activation setting, and physical partition
configuration.
