Connecting Drive Cables

When you install a drive, you connect two cables—a DC power cable and an interface cable—to the back of the drive.

Power Cable Connector

1 Power cable
2 Power input connector

Drive Interface Connector

1 Interface connector
2 Colored stripe on cable
3 Interface cable

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 (indicated by the colored

stripe 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 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.
