When you attach the interface cable to a drive, be sure to match the colored strip on the cable to pin 1 of the drive
’s interface connector. For the
location of pin 1 on the drive
’s interface connector, see the documentation that came with the drive.
When you disconnect an interface cable from the system board, be sure to press in on the locking tabs on the cable connector before you
disconnect the cable. When you attach an interface cable to the system board, be sure that the locking tabs snap into place so that the cable is
firmly attached to the connector on the system board.
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the
other connector (see
). Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored strip along one edge of the
cable) goes to the pin-1 end of the connector.
The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or card.
NOTICE: When you connect an interface cable, do not reverse the interface cable (do not place the colored strip away from pin 1 of
the connector). Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.
