Troubleshooting Overview
The HP workstation c8000 includes several tools to help you troubleshoot potential problems.
Many problems have simple solutions, so try the tools and suggestions covered in this section
before contacting HP support. The following sections provide additional information about:
■ Identifying and diagnosing hardware problems

Identifying and Diagnosing Hardware Problems
For basic troubleshooting tips, see the HP workstation c8000 Getting Started Guide. If you need
further help with a hardware failure, the system LEDs and logs will help you identify the
problem:
■ LEDs. The lights on the front and rear panels of the workstation change color and blink in
different patterns to help identify specific hardware problems.
❏ LAN Activity LEDs
❏ Hard Disk Activity LED
❏ System Status and Diagnostic LEDs
❏ System Board LED
■ The BCH Error and Warning Messages provide additional detailed information about
errors identified by the LEDs.
If the LEDs and log files do not provide enough information for you to identify the problem you
are experiencing, HP also provides software diagnostic tools.
NOTE: See Chapter 2, “System Configuration” for detailed instructions on removing and
replacing system components.
