Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—or a single
interface cable to the back of the drive and to the system board.
Drive Interface Connectors
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. Serial ATA cables go 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 a SATA interface cable, do not place the colored stripe away from pin 1 of the
connector. Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.
Power Cable Connector
To connect a drive using the power cable, locate the power input connector on the system board.
