19.1 Ports for Crossbar Cable Connection
Use either crossbar cables (optical) or crossbar cables (electrical) exclusively for the
connections of each SPARC M12-2S. Use only crossbar cables (optical) for the
connections between a crossbar box and the SPARC M12-2S.
When there is the need for crossbar cable replacement, replace crossbar cables in
pairs, with each cable connected
to a port assigned the same port number.
■
SPARC M12-2S
A crossbar cable is connected to a crossbar cable connection port of the XBU in the
SPARC M12-2S.
Every two adjacent crossbar cable connection ports of the XBU make up a pair,
and the same port number is assigned to these two ports.
■
Crossbar box
A crossbar cable is connected to a crossbar cable connection port of the crossbar
box.
Every two vertically adjacent crossbar cable connection ports make up a pair, and
the same port number is assigned to these two ports.
Figure 19-1 and Figure 19-2 show the locations and configurations of the
ports for
crossbar cable connection.
