A diskette drive and CD-ROM drive come preinstalled in all systems.
 Pre-installation Steps
Consider the following cautions when installing or removing media drives into your
system unit.
 Use caution when handling all disk drives. Disk drives are more likely to be
damaged during installation and service than at any other time. A fall of as little
as .25 inch, bumping, or rough handling can all cause latent failures.
 Media drives are particularly sensitive to electrostatic discharge. Follow the
electro-static handling procedures prior to handling the media drive.
 Refer to the documentation that came with your drive to determine if any
drive-specific procedures must be followed, such as setting switches or jumpers,
or attaching the drive to a carrier tray.
 Media SCSI drives must have their SCSI address set manually. Refer to the
documentation that came with your drive for more information on setting the
SCSI address. Refer to “SCSI IDs and Bay Locations” on page 1-6 for more
information on SCSI addresses in your system unit.
