24.1 Configuration of the Ports for the

Crossbar Cables (Electrical)

Thissection describes the configuration and the location of the ports that are used for

connecting crossbar cables (electrical).

Thecr ossbar cables (electrical) are used make interconnections between SPARC

M10-4Ssystems.

Eachcr ossbar cable (electrical) has a number that corresponds to a port number on

thech assis. A port number is assigned to each pair of ports. Crossbar cables

(electrical) should be replaced as a pair, therefore.
