Diagnostic tools overview The following tools are available to help you diagnose and solve hardware-related problems: v POST 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 "POST beep codes," and the Problem Determination and Service Guide on the IBM xSeries Documentation CD for more information. v Troubleshooting charts These charts list problem symptoms and steps to correct the problems. See "Troubleshooting charts" on page 53 for more information. v Diagnostic programs and error messages The system diagnostic programs are provided in ROM. These programs test the major components of the server. See the Problem Determination and Service Guide on the IBM xSeries Documentation CD for more information. v Light path diagnostics Use light path diagnostics to diagnose system errors quickly. See "Light path diagnostics" on page 60 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 Problem Determination and Service Guide on the IBM xSeries Documentation CD for more information about the POST beep codes. One beep POST was completed successfully without finding any errors. Two short beeps The server configuration has changed.
