Removing and Installing Parts
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. Keyed connectors ensure that the pin-
1 wire in the cable (indicated by the colored stripe along one edge of the IDE cable—serial ATA cables do
not use a colored stripe) 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 IDE 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.
