when handling static-sensitive devices, take precautions to avoid damage from static electricity.
1.read the information in "preinstallation steps (all bays)" on page 38.
2.turn off the computer and attached devices and disconnect the external cables and power cords.
3.remove the side cover (see "removing the side cover" on page 32 for details).
4.remove the support bracket see "removing the support bracket" on page 33.
5.use a screwdriver to pry the filler panel and emc shield away from the computer.
if you are installing a drive that contains a laser,observe the following safety precaution.
laser radiati on when open. do not stare into the beam, do not view directly with optical instruments,and avoid direct exposure to the beam.
6.touch the static-protective bag containing the drive to any unpainted metal surface on the computer; then remove the drive from the bag and place it on a staticprotective surface.
7.set any jumpers or switches on the drive according to the documentation that comes with the drive.
8.you might find it easier to install the new drive into the appropriate opening on the machine front,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.
10.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.
you can install only a 3.5-in. device in bay 4.
11.if the drive is an ide device, connect one end of the ide signal cable into the back of the drive and the other end of the cable into the ide connector on the system board. for the location of the ide connectors, see "internal cable connectors" on page 29. if the drive is a scsi device, connect one end of the scsi signal cable into the back of the drive and the other end of the cable into the scsi adapter.
make sure to route the scsi signal cable so that it does not block the air flow to the rear of the drives or over the microprocessor.
12.connect a 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.
15.go to the appropriate section to work with another option, or replace the side cover,see "replacing the cover" on page 44 for details.
16.reconnect the external cables and power cords; then turn on the attached devices and the computer.
