2.5 Confirming the Types of Cable
This section describes the types of cables connected to the SPARC M10-4/M10-4S and
the locations of the ports.
The types and number of the cables to be used vary depending on the configuration.
2.5.1 Types of cable
In a building block configuration, the following cables are used for making a
connection between the SPARC M10-4S systems and between the SPARC M10-4S
and the crossbar box:
■
Crossbar cable
In a building block configuration, this is used to connect the SPARC M10-4S units
to each other or to connect the SPARC M10-4S to a crossbar box.
■
XSCF BB control cable
This is used to connect the XSCFs mounted in the SPARC M10-4S or crossbar box
chassis.
An XSCF mounted in a chassis becomes the master XSCF and monitors or controls
the entire system. XSCFs other than the master XSCF act as slaves and monitor or
control each chassis.
■
XSCF DUAL control cable
This is used to connect the master XSCF to a standby XSCF and duplicate XSCF.
One of the slave XSCFs functions as the standby XSCF. If an abnormality occurs
