5-12 Problem Solving
Diskette Drive Activity LED Does Not Light
Check the following:
„
Are the diskette drive power and signal cables properly installed?
„
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 Setup or the SSU
to make sure that Onboard Floppy is set to Enabled. Conversely, to use
an optional fixed/diskette controller, make sure that Onboard Floppy is
set to
Disabled . For information about running Setup or the SSU, refer
to the “Configuring Your System” chapter.
If the problem persists, there may be a problem with the diskette drive,
system board, or drive signal cable. Contact your service representative
for assistance.
Hard Disk Drive Activity LED Does Not Light
If you have installed one or more hard disk drives in your system, check
the following:
„
Are the power and signal cables to the drive properly installed?
„
Are all relevant switches and jumpers on the hard drive and adapter
board set correctly?
„
Is the hard disk drive properly configured in the SSU?
Run the SSU to make sure that the hard disk drive is configured with
the correct parameters. For information about running the SSU, refer to
the “Configuring Your System” chapter.
If the problem persists, there may be a problem with the hard disk
drive, the optional controller board, system board, drive signal cable, or
LED connector. Contact your service representative for assistance.
Note: The hard disk drive activity light on the front panel
lights when a hard disk drive, or a SCSI device controlled by
the onboard SCSI host controller, is in use. This LED does not
display CD-ROM activity.
