1 colored stripe on IDE cable 2 data cable connector 3 system board connector Connect IDE CD/DVD drives to the connector labeled "IDE" on the system board. Connect SATA CD/DVD drives to the connector labeled "SATA2" or "SATA3." SATA hard drives should be connected to the connectors labeled "SATA0" or "SATA1" on the system board. To locate system board connectors, see System Board Components. IDE Drive Addressing When you connect two IDE devices to a single IDE data cable and configure them for the cable select setting, the device attached to the last connector on the data cable is the master or boot device (drive 0), and the device attached to the middle connector on the data cable is the slave device (drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting. Power Cable Connectors IDE Drive Power Connector SATA Power Connector 1 power cable 2 power input connector Connecting and Disconnecting Drive Cables Most 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-SATA 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. When removing an IDE data cable, grasp the colored pull-tab and pull until the connector detaches. When connecting and disconnecting a SATA data cable, hold the cable by the black connector at each end. NOTICE: When you connect an IDE data 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.
