necessary for the 9BB configuration or larger.
Direct connections between chassis (without an
expansion rack)
A configuration with direct connections between chassis (without an expansion rack)
directly connects each SPARC M10-4S unit with crossbar cables (electrical). It can be
expanded to up to the 4BB configuration.
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.
