Connecting Drive Cables When you install a drive, you connect two cables-a DC power cable and a data cable-to the back of the drive and to the system board. Drive Interface Connectors Serial ATA Connector 1 interface cable connector 2 interface connector 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. Keyed connectors ensure that the pin-1 wire in 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.
