NOTE: You may have to remove the drive from the computer to
perform the next two steps.
3. Hold the ATAPI cable at or near the base of its connection to the
PX-760A drive. Carefully remove the ATAPI cable from the drive
by pulling the cable gently rearward.
4. Note the position of the mode jumper at the rear of the PX-760A. 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, leave it in place.
If the jumper is on the Slave position, leave it in place.
If the jumper is on the Cable Select position, move it to the
Master position.
5. Install an extra jumper so that both the Master and Slave positions
are jumpered, as shown in Figure 38.
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. Turn the computer power on. The LED indicator blinks green, then
amber, and the tray ejects.
