Chapter 5. Diagnostics

This chapter describes the diagnostic tools that are available to help you solve problems that might occur in the server.

If you cannot diagnose and correct a problem by using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 247 for more information.

Diagnostic tools

The following tools are available to help you diagnose and solve hardware-related problems:

vPOST 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 “POST” for more information.

vTroubleshooting tables

These tables list problem symptoms and actions to correct the problems. See “Troubleshooting tables” on page 147.

vServer LEDs

Use the LEDs on the server to diagnose system errors quickly. See “Error LEDs” on page 160 for more information.

vDiagnostic programs and messages

The diagnostic programs on the Diagnostics CD are the primary method of testing the major components of the server. See “Diagnostic programs and messages” on page 163 for more information.

POST

When you turn on the server, it performs a series of tests to check the operation of the server components and some optional devices in the server. This series of tests is called the power-on self-test, or POST.

If a power-on password is set, you must type the password and press Enter, when you are prompted, for POST to run.

If POST is completed without detecting any problems, one short beep occurs, and the server startup is completed.

If POST detects a problem, several beeps might sound, or an error message is displayed. See “POST beep codes” on page 130 and “POST error codes” on page 135 for more information.
