11. Touch the static-protective package containing the drive to any unpainted metal
surface on the computer; then, remove the drive from the package and place it
on a static-protective surface.
12. Follow the instructions that come with the drive to set jumpers or switches, if
any.
Notes:
a. You might find it easier to install the new drive into the opening on the front
and then attach the cables.
b. If you are installing a hard disk drive, you might need to temporarily
disconnect the front-panel cable from the system board. You can reconnect
the front-panel cable after you have finished installing the hard disk drive.
13. Push the drive into the bay; then, use the one screw to attach the drive to the
drive cage.
Note: It is not necessary to secure the drive with two screws.
14. Connect one end of the applicable signal cable into the back of the drive and
the other end of this cable into the applicable connector on the system board
(if you are installing a diskette drive in bay 3, connect the other end of the
cable to the diskette connector on the system board). See “Power and signal
cables for internal drives” on page 44 for additional information about cabling
drives and “System-board internal connectors” on page 77 for the location of
diskette and SCSI connectors on the system board. If there are open
connectors on the cables connecting existing SCSI drives, you can use these
cables to connect the new drive.
15. Route the signal cable so that it does not block the airflow to the rear of the
drives or over the microprocessor.
16. Connect the power cable to the back of the drive. The connectors are keyed
and can be inserted only one way.
17. If you have other options to install or remove, do so now.
18. Lower the drive cage.
19. Replace the support bracket (see “Replacing the support bracket” on page 29).
20. Replace the bezel (see “Replacing the bezel” on page 30).
21. Replace the side cover (see “Replacing the side cover” on page 27).
22. Reconnect the external cables and power cords; then, turn on the attached
devices and the computer.
To remove a drive from bay 3, reverse the preceding steps.
Replacing a hard disk drive in bay 4, 5, or 6
Bays 4, 5, and 6 are in the drive cage. The drive cage is near the front
adapter-support bracket.
Note: When installing hard drives, you might find it easier to work with the
computer lying on its side.
Complete the following steps to install a drive in bay 4, 5, or 6:
1. Read the safety information in Appendix B, “Safety information,” on page 117,
the guidelines in “Handling static-sensitive devices” on page 25, and the
documentation that comes with the drive.
2. Make sure that you have all the cables and other equipment that is specified in
the documentation that comes with the drive.
