Cable Command
The Cable command displays the current cable length settings for the two Host
ports and the Expansion port. The I/O module supports cables from 1 to 8 meters
in length.
To view current settings:
cli>cable
The system returns:
CN#1 Cable Length = 1 meter
CN#2 Cable Length = 1 meter
CN#1 and CN#2 are the external SAS connectors on the I/O module. CN#1 is
labeled with a circle icon. CN#2 is labeled with a diamond icon. See Figure 3.
To set Expansion connector CN2 for a 3-meter cable:
cli> cable -a mod -s “cn2=3”
To verify the setting change:
cli>cable
Note
Command options are case-sensitive. Disable the Caps Lock on
your keyboard.
