Removing and Installing Parts: Dell XPS 400 Service Manual connector and the other will attach to the system board. Connect hard drives to data connectors labeled "SATA" and connect CD/DVD drives to connectors labeled "IDE". When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device attached to the last connector on the interface cable is primary or the boot device (drive 0), and the device attached to the middle connector on the interface cable is the secondary device (drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting. 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. When connecting an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When disconnecting an IDE cable, grasp the colored pull tab and pull until the connector detaches. When connecting and disconnecting a serial ATA cable, hold the cable by the connector at each end. Like IDE connectors, the serial ATA 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.

connector and the other will attach to the system board.
Connect hard drives to data connectors labeled "SATA" and connect CD/DVD drives to connectors labeled "IDE".
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device
attached to the last connector on the interface cable is primary or the boot device (drive 0), and the device attached to the
middle connector on the interface cable is the secondary device (drive 1). See the drive documentation in your upgrade kit for
information on configuring devices for the cable select setting.
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.
When connecting an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When disconnecting an IDE
cable, grasp the colored pull tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA cable, hold the cable by the connector at each end. Like IDE connectors, the
serial ATA 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.
