Chapter 5. Solving problems

This chapter provides basic troubleshooting information to help you solve some common problems that might occur while you are setting up the server.

If you cannot locate and correct the problem using the information in this chapter, see Appendix A, “Gettinghelp and technical assistance,” on page 81, the Hardware Maintenance Manual on the ThinkServer Documentation DVD.

Diagnostic tools overview

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

vPOST beep codes

The power-on self-test beep codes indicate the detection of a problem.

–One beep indicates successful completion of POST, with no errors.

–More than one beep indicates that POST detected a problem. Error messages also appear during startup if POST detects a hardware-configuration problem.

See “POSTbeep codes” and the Hardware Maintenance Manual on the ThinkServer Documentation DVD for more information.

vDiagnostics DVD

The Diagnostics DVD provided with your server contains the diagnostic programs for testing the major components of the server. For additional information about the Diagnostics DVD, see the Hardware Maintenance Manual on the ThinkServer Documentation DVD.

vTroubleshooting tables

These tables list problem symptoms and steps to correct the problems. See “Troubleshootingtables” on page 65 for more information.

vDiagnostic programs and error messages

The system diagnostic programs are provided in ROM. These programs test the major components of the server. See the Hardware Maintenance Manual on the ThinkServer Documentation DVD

vLight path diagnostics

Use light path diagnostics to diagnose system errors quickly. See “Lightpath diagnostics” on page 77 for more information.

POST beep codes

POST emits one beep to signal successful completion. If POST detects a problem during startup, other beep codes might occur. Use the following beep code descriptions to help diagnose and solve problems that are detected during startup.

Note: See the Hardware Maintenance Manual on the ThinkServer Documentation DVD for more information about the POST beep codes.

One beep

POST was completed successfully without finding any errors.

One long beep and two short beeps

A video error has occurred, and the BIOS cannot initialize the monitor screen to display additional information.
