Connecting Drive Cables - Dell Dimension U7021 Owner's Manual

Connecting Drive Cables

When you install a drive, you connect two cables—a DC power cable and a data cable—to the back
of the drive and to the system board. Some drives may also have an audio connector; one end of the
audio cable attaches to the drive connector and the other end attaches to the system board.
Drive Interface Connectors
Serial ATA Connector

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.
When you connect an IDE cable, ensure that you align the colored stripe with the pin 1 connector.
When you disconnect 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.
NOTE:
The system board serial ATA connector may have an attached cover or shroud.
