ULTRAPLEX 40X OPERATION MANUAL

Drive Switch/Jumper/Dial Settings
YOUR TASK:
Find the location of the jumpers (internal drive) or
switches and rotary dial (external drive). Check their
settings. Change them if necessary.
YOUR OBJECTIVE:
To ensure that your new CD-ROM drive can coexist
peacefully with other equipment you might have
installed in your computer. To ensure that your drive
will work properly after it is installed.
YOUR METHOD:
Find locations of the jumpers, the switches, and the
rotary dial on the diagram in Chapter 5. Read below
to determine if your drive’s settings need to be
changed. If so, follow the directions on making the
necessary changes.
Your UltraPleX CD-ROM drive needs to be flexible enough to work with a
variety of computer systems (PC, Apple, Sun, Silicon Graphics, Linux, etc.) that
can use SCSI peripherals. To provide this flexibility, Plextor gives its customers
options for drive setting prior to installation. On an internal drive, settings are
determined by the position of jumpers on the jumper block at the rear of the
drive. On an external drive, settings are determined by the position of DIP
switches and the rotary dial on the rear panel of the drive.
Fortunately, we have a pretty good idea of the environment in which most of our
drives will be used (a single SCSI device connected to a PC or Mac). Your drive ships
from our factory with its jumpers, switches, and dial set to work in this
environment.
Apple and PC users should leave the settings of your UltraPleX at their factory
default unless: 1) you plan to use another SCSI peripheral (e.g., hard disk, CD-R,
or scanner) with your computer system in addition to your CD-ROM drive; or
2) you find it necessary to change the device type setting (most likely in an
older UNIX system).
If you plan to use additional SCSI peripherals, you may need to change the
jumper, switch, and dial settings of the UltraPleX. This section will describe how
to make these changes. For instructions, page 20.
If the CD-ROM drive is the only SCSI peripheral you will use with your
computer, or you do not need to boot from the CD-ROM drive in a UNIX
environment, or if you do not plan to use the Eject Lock feature, skip now to
