Command Cables
The CMDO, CMDX and CDRO cables are all cables that plug into the Command Connector.
The CMDO and CMDX cables both use the same straight connector style, same color code
and carry the full complement of signals available from the Command Connector. The
difference is the CMDO cable has a male connector on one end with open wires on the other
while the CMDX cable has male connectors on both ends.
For information about CMDO-XXX and CMDX-XXX (18 pair cable) cable wire colors see
the "Specifications" section.
Note
Some CMDO and CMDX cables may have White/Yellow and Yellow/White wires in
place of the White/Orange and Orange/White shown in the figure above (pins 6 and 21).
The CDRO cable includes only the most commonly used signals to reduce the cable outer
dimension and has a connector at only one end. The 45 degree connector design used on the
CDRO cable also reduces the enclosure spacing requirement below the drive.
For information about the CDRO-XXX (13 pair) cable wire colors, see the "Specifications"
section.
