Note: You might find it easier to install the new drive into the appropriate
opening on the front, and then attach the cables.
9. If you are installing a 5.25-in. drive in bay 2, push the drive into the bay; then,
use the two screws to attach the drive to the drive cage. If you are installing a
3.5-in. drive in bay 2, you must attach the 5.25-in. conversion kit, supplied with
your option, to the 3.5-in. drive.
10. Determine whether the drive is an IDE or SCSI device; then, connect one end
of the appropriate signal cable into the back of the drive and make sure that
the other end of this cable is connected into the appropriate IDE or SCSI
connector on the system board. See "Power and signal cables for internal
drives" on page 53 for additional information about cabling drives and
"System-board internal connectors" on page 37 for the location of IDE and
SCSI connectors on the system board. If there are open connectors on the
cables connecting an existing IDE drive, this cable can be used to connect the
new drive. The 3-connector SCSI cable that comes with your computer cannot
be used to connect a SCSI drive in bay 2.
11. Route the signal cable so that it does not block the air flow to the rear of the
drives or over the microprocessor and memory.
12. Connect the power cable to the back of the drive. The connectors are keyed
and can be inserted only one way.
13. If you have other options to install or remove, do so now.
14. Replace the support bracket (see "Removing and installing the support
bracket" on page 42).
15. Replace the side cover (see "Replacing the side cover" on page 62).
16. Reconnect the external cables and power cords; then, turn on the attached
devices and the computer.

2. Turn off the computer and all attached devices.
3. Disconnect all power cords; then disconnect all external cables.
4. Remove the side cover (see "Removing the side cover" on page 39).
5. Remove the front bezel (see "Front bezel" on page 40).
6. Remove the support bracket (see "Removing and installing the support
bracket" on page 42).
7. Rotate the drive cage out.
8. Remove the existing drive by disconnecting the cables in the rear of the
diskette drive; then, press on the oval cutout to release the drive and gently
pull it out the front.
