IBM 71P7279 manual Setting the configuration jumper, Mounting the drive in the bay

or secondary. See the documentation that came with your computer to determine if your computer supports this setting.

Step 4. Setting the configuration jumper

The illustration shows the primary	setting, the secondary (or slave)
setting, and the cable-select	setting. Configure the CD-ROM drive by

placing the jumper over the set of pins corresponding to the setting you chose in Step 3. See “Step 3. Selecting the IDE port” on page 1-4.

vIf you are configuring the CD-ROM device as primary, set the jumper to the

master device setting. (This is how the drive is set when it is shipped.) If there is a second device on the IDE port, make sure that device is configured as secondary.

vIf you are configuring the CD-ROM device as secondary, set the jumper to

the secondary device setting. Make sure that the other device on the IDE port is configured as primary (or primary-with-secondary-present).

vIf you are configuring the CD-ROM device as cable-select, set the jumper to

the cable-select device setting. If there is another device on the IDE port, make sure that the second device is also configured for cable-select.

Step 5. Mounting the drive in the bay

Attention: Be sure to use the M3 x5 mm mounting screw in the option package. Using screws that are too long might damage the drive

You can mount the CD-ROM drive horizontally or vertically in the computer. If you mount the drive vertically, you must secure any CDs you place into the drive before the drive tray is closed, or the CD-ROM drive will not be able to read the CD correctly. For further instructions on securing your CDs in a vertically mounted drive, go to “Loading a CD” on page 1-9.

1.Slide the drive into the bay. Your computer might have specific required procedures for installing storage devices. Refer to the documentation that came with your computer for further instructions.

2.Align the drive-bay screw holes with the threaded holes in the drive housing or mounting bracket; then thread the screws in loosely to check their positions. Usually two screws are used on each side.
