System Troubleshooting
This chapter describes the most common operating problems, the
probable causes, and recommended corrective actions including:
• Troubleshooting procedure
• Troubleshooting checklists
• Boot-up error messages
• General error and information messages
To help identify and isolate a problem, we recommend that you do the
following when a problem occurs:
1. Disconnect power to the 6155 Computer.
2. Disconnect any peripheral devices such as printer or scanner.
3. Check the video connections if using an external monitor.
4. If the system normally boots from the hard drive, make sure there is
not a diskette in the floppy drive.
5. Apply power and observe the LEDs on the front panel (if present).
Make sure the power on indicator is illuminated.
6. Monitor the Power On Self Test (POST). One of 3 events will occur:
• The 6155 Computer will complete the boot-up process.
• An error message will occur indicating a non-fatal fault. You
may have to acknowledge the message before the boot-up
process is allowed.
• The boot-up process will terminate (fatal error).
7. If the system boots up, isolate the problem by connecting peripheral
devices one at a time until the problem occurs. If the problem is with a
specific software package or driver, you may want to re-install the
software.
8. If there is a problem not related specifically to a software installation
or peripheral device, refer to the following troubleshooting checklists.
