If you are installing a hard disk drive in the upper horizontal bay, make sure you use the proper hard disk drive ribbon cable and connect the drive to the hard disk drive connector. Also, if this is the second hard disk drive in your system, make sure you set the jumpers on both hard disk drives to indicate which is the master and which is the slave drive.

2.If the drive connector extending from the back of the drive has gold contacts on both sides, use the card-edge connector on the ribbon cable. Make sure you align the

key-way (the plastic divider) with the gap in the drive

c o n n e c t o r .

If the drive connector contains a series of pins, use the header connector. Identify pin 1 on the drive and align the connector so that the red wire is at pin 1.

3.Locate one of the power supply cables that lead from the power supply. (They have multi-colored wires and a plastic connector on the end.)
