NOTE: The power cable for the hard drives is a two-headed cable that is routed from the power
supply to the rear of the hard drive bays.
6. If installing a new drive, connect the opposite end of the data cable to the appropriate system
board connector.
NOTE: You must connect the primary hard drive data cable to the dark blue connector labeled
SATA0 to avoid any hard drive performance problems. If you are adding a second hard drive,
connect the data cable to the light blue SATA connector labeled SATA1.
