When attaching 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 disconnecting an interface cable from the system board, be sure to press in on the locking tabs on the
cable connector before disconnecting the cable. When attaching an interface cable to the system board, be
sure that the locking tabs snap into place, ensuring that the cable is firmly attached to the connector on the
system board.
NOTICE: When connecting 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.
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
). Keying ensures 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 card-edge connector is usually identified by a notch cut about a quarter of an inch from
the end of the connector, as shown in
. A header connector is usually keyed by the omission of one
), with the corresponding hole filled in on the connector cable.
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.
