Chapter 5. Troubleshooting
This chapter provides basic troubleshooting information to help you resolve some
common problems that might occur with your appliance.
If you cannot locate and correct the problem using the information in this section,
refer to “Appendix B. Getting help, service, and information” on page 45 for more
information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v
POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “Power-on self-test”
on page 51 for more information.
POST error messages and descriptions are given in “Appendix D. POST error
messages” on page 51.
v
Diagnostic programs and error messages
The diagnostic programs are stored in upgradable read-only memory (ROM) on
the system board. These programs are the primary method of testing the major
components of your appliance. See “POST diagnostic programs” on page 62 for
more information.
v
Light-path diagnostics
Your appliance has light-emitting diodes (LEDs) to help you identify problems
with appliance components. These LEDs are part of the light-path diagnostics
that are built into your appliance. By following the path of lights, you can quickly
identify the type of system error that occurred. See “Light-path diagnostics” on
page 28 for more information.
