Dell OptiPlex 320 - Manual (Page 32)

Connect an IDE CD/DVD drive to the connector labeled "IDE" on the system board. Connect a SATA CD/DVD drive to the connector labeled "SATA1." 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

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
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.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before removing the computer cover.
