CAUTION: Before you begin any of the procedures in this section,
follow the safety instructions on page 7.
Your computer includes one 3.5-inch drive. To add a second 3.5-inch drive:
1 Turn off the computer and devices, and disconnect them from their
electrical outlets.
NOTICE: To disconnect a network cable, first unplug the cable from your
computer and then unplug it from the network jack on the wall.
2 Press the power button.
Pressing the power button when the computer is not connected to an
electrical outlet discharges residual electricity and can help prevent
system board damage.
3 Remove the computer cover (see page 60).
