Chapter 6. Solving problems This section 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, "Getting help and technical assistance," on page 71, the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD, and the "Server Support" flowchart in the front of this document. Diagnostic tools overview The following tools are available to help you diagnose and solve hardware-related problems: v POST beep codes and error messages The power-on self-test (POST) 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 code descriptions" on page 60 and the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD for more information. v ServerGuide problems chart This chart lists problem symptoms and steps to correct problems that occur when you are using the ServerGuide Setup and Installation CD. See the "ServerGuide problems" on page 62 for information. v Troubleshooting charts These charts list problem symptoms and steps to correct the problems. See "Troubleshooting charts" on page 63 for more information. v Diagnostic programs and error messages The system diagnostic programs are provided on the Diagnostics CD. These programs test the major components of the server. See the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD for more information. v System-board error LEDs An LED on the system board might also be lit to help isolate an error indicated by the system-error LED on the front of the server. See "System-board LEDs" on page 10 for more information. v Light path diagnostics Use light path diagnostics to diagnose system errors quickly. See "System-board error LEDs" on page 68 for more information. © Copyright IBM Corp. 2004 59
