4. Note the position of the mode jumper at the rear of the PlexWriter. A jumper will
be installed on either the CABLE SELECT, SLAVE, or MASTER position.
Write down this jumper position. (You’ll need to replace the jumper after the
test.) Then:
If the jumper is on the MASTER position, move it to the SLAVE or CABLE
SELECT position for this test.
If the jumper is on the SLAVE or CABLE SELECT jumper, leave it in
place.
5. Install the spare jumper, located in the accessory kit, so that both the CABLE
SELECT and SLAVE positions are jumpered, as shown below.
Figure 20. Place Jumpers Across Both the SLAVE and CABLE SELECT Pins to
Perform the Self-Test Diagnostics.
6. If you removed the drive for access to the cable and mode jumpers, slide it back
into the computer and connect the power cable to the drive.
7. Replace the computer’s cover and re-connect the computer’s power cord to the
power source.
CAUTION: Turning on the computer power without first replacing the cover can be
dangerous to the computer’s components and also to you. Be aware of the danger of
electric shock and do not touch any components inside the computer.
8. While pressing the eject button on the PlexWriter, turn the computer power on.
The LED indicator blinks green and amber and the tray ejects.
9. Insert a blank Plextor-recommended CD-R disc. Be sure to use only CD-R media
of the type recommended by Plextor.
If the DISC indicator blinks amber three times, the loaded disc is not a blank
CD-R disc. Remove the disc and insert a blank, Plextor-approved CD-R disc.
