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 hard disk drive properly
installed?
Is the optional disk controller board fully seated in the system
board connector?
Are all relevant switches and jumpers on the hard disk drive
and controller board set correctly?
Are the jumpers on the system board set correctly?
Is the hard disk controller properly configured in the ECU?
Is the hard disk activity LED cable connector plugged into the
optional controller board, if present?
If you received error messages, refer to the “Error Messages”
section for information about error messages.
If you did not receive error messages, run the ECU to make sure
that the hard disk drive is configured with the correct
parameters. For information about running the ECU, 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.
