11–2 System Troubleshooting
Publication 6181-UM001D-EN-P
To help identify and isolate a problem, we recommend that you do the
following when a problem occurs:
1. Disconnect power to the RAC6181 Computer.
2. Disconnect any peripheral devices such as printer or CD-ROM drive.
3. Connect the keyboard and mouse (if used) to the side panel
connectors. These connectors are connected directly to the processor
board.
4. Check the video connections if using an external monitor.
5. If the system normally boots from the hard drive, make sure there is
not a diskette in the floppy drive.
6. Apply power and observe the LEDs on the front panel (if present).
Make sure the power on indicator is illuminated.
7. Monitor the Power On Self Test (POST). One of 3 events will occur:
•
The RAC6181 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).
8. 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.
9. If there is a problem not related specifically to a software installation
or peripheral device, refer to the following troubleshooting
checklists.
