Lenovo TD100 manual Diagnostic tools, Post beep codes, error messages, and error logs, Server LEDs

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 locate and correct the problem using the information in this chapter, see “Getting help and technical assistance” on page 217 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 172.

vServer LEDs

Use the LEDs on the server to diagnose system errors quickly. See “Error LEDs” on page 186 for more information.

vDiagnostic programs, messages, and error messages

The diagnostic programs are the primary method of testing the major components of the server. The diagnostic programs are on the Diagnostics CD that comes with the server. See “Diagnostic programs, messages, and error codes” on page 189 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 prompted, for POST to run.

If POST is completed without detecting any problems, a single beep sounds, and the server startup is completed.

If POST detects a problem, more than one beep might sound, or an error message is displayed. See “POST beep codes” on page 148 and “POST error codes” on page 155 for more information.
