Confirming the Types of Cable

This section describes the types of the cables that are connected to the SPARC
M10-4/M10-4S and the crossbar box, as well as the locations of the cable ports.
The types and number of the cables to be used vary depending on the configuration.
2.4.1

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 (electrical)
■
This is used to connect the SPARC M10-4S systems in a building block configuration
without the crossbar box.
Crossbar cable (optical)
■
This is used to connect the SPARC M10-4S with the crossbar box in a building
block configuration with the 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
with the master XSCF, the standby XSCF becomes the master XSCF and continues
the monitoring or control of the system.
Each table has a tag that is used for maintenance recording and management.
