5-10 Solving Problems
Is the power indicator on the front panel lit?
Is the power supply failure indicator on the power supply lit? If not, the
power supply has failed.
Is the power connector for the cooling fan(s) connected to the system
board?
Is the cable from the front panel board connected to the system board?
If the switches and connections are correct and the power outlet is functioning,
contact your service representative for assistance.
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 the Setup or SSU to make
sure that the 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 the Setup or SSU, refer to Chapter 3, “Configuring
Your System,” or Appendix B, “System Setup Utility.”
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?
Is the individual hard drive activity indicator on the front panel lit?
Is the disk bay power indicator on the front panel lit?
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.
