Drive Switch/
Jumper/Dial Settings
YOUR TASK:
Find the location of 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 jumpers/switches/rotary dial on
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 12PleX CD-ROM drive needs to be flexible enough to work with the variety of
computer systems (PC, Mac, Sun, Silicon Graphics, DEC, etc.) that can use SCSI
peripherals. To provide this flexibility, Plextor gives its customers options on how a
drive can be set before it is installed. 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.
NOTE:
Silicon Graphics computers are somewhat proprietary, and historically you
needed to buy a Silicon Graphics CD-ROM drive. Now you can purchase
kits from Plextor that are specially configured for SGI.
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/dial set to work in this environment.
You should leave the jumpers found on the rear panel of the PX-12XSi and the switches
and rotary dial found on the rear panel of the PX-12XSe at their factory settings unless:
1) you plan to use another SCSI peripheral (e.g., hard disk, scanner) attached to the
same SCSI adapter, in addition to your CD-ROM drive; 2) you work in a UNIX
environment and want to boot from your CD-ROM drive; 3) you want to utilize the
Eject Lock feature. If you plan to use additional SCSI peripherals, you may need to
change the jumper/switch/dial settings of the 12PleX. This section will further describe
how to make these changes. For more information on #2 and #3, see page 18.
