Connecting the Cables
To connect the hard disk drive to the computer, you need to
connect two cables: the hard disk drive ribbon cable and a
power supply cable. Follow the steps below:
1. If you are installing your computer’s first hard disk drive,
you need to connect the hard disk drive ribbon cable to the
system board now. Follow the instructions on page 5-30
and then return here.
2. The hard disk drive ribbon cable should be connected to the
main system board. Locate the free connector on the end of
this cable. (If there is a hard disk drive in the lower
horizontal bay, the middle connector is attached to that
drive.)
3. Notice the small tab in the middle of the cable connector;
align this tab with the notch in the hard disk drive
connector, as shown in the following illustration.
Note
When the hard disk drive ribbon cable is positioned
correctly, the red wire on the cable aligns with pin 1 on
the drive connector. To identify pin 1, look for a 1 or 2 at
the connector on the drive’s circuit board.
