9. Connect the power and data cables to the back of the hard drive.
NOTE: When replacing the primary hard drive, be sure to route the SATA and power cables
through the cable guide on the bottom of the chassis frame behind the hard drive.
If the system has only one SATA hard drive, the data cable must be connected to the dark blue
connector labeled SATA0 on the system board to avoid any hard drive performance problems. If
you are adding a second hard drive, connect the other end of the data cable to the next available
(unpopulated) SATA connector on the system board in the following order: SATA0, SATA1, SATA2.
10. Rotate the drive cage for external drives and the power supply down to their normal positions.
NOTE: If you are replacing the primary hard drive, use the Recovery Disc Set to restore the operating
system, software drivers, and any software applications that were preinstalled on the computer.
