Diskette Drive Activity Light Does Not Light

Check the following:
❑ Are the power and signal cables to the diskette drive properly installed?
❑ Are all relevant switches and jumpers on the diskette drive set correctly?
❑ Is the diskette drive properly configured?
❑ Is the diskette drive activity light always on? If so, the signal cable may be plugged in
incorrectly.
If you are using the onboard diskette controller, use the SSU to make sure that controller is
enabled. If you are using an add-in diskette controller, make sure that the onboard controller is
disabled. (Chapter 5)
If the problem persists, there may be a problem with the diskette drive, PHP I/O baseboard, or
drive signal cable. Contact your service representative or authorized dealer for assistance.

❑ Is the hard disk drive properly configured?
❑ Are the SCSI signal cables properly connected to the peripheral bay backplane?
If you received error messages, refer to "Error Codes and Messages" on page 269 for information
about error messages.
If you did not receive error messages, run the SSU and make sure the hard disk drive is configured
with the correct parameters. (Chapter 5)
If the problem persists, there may be a problem with the hard disk drive, PHP I/O baseboard, drive
signal cable, or LED connector. Contact your service representative or authorized dealer for
assistance.
