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. - 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 58 and the blade server Hardware Maintenance Manual and Troubleshooting Guide on the IBM BladeCenter Documentation CD or the IBM BladeCenter T Documentation CD that comes with your BladeCenter unit for more information. v ServerGuide problems This table lists problem symptoms and steps to correct the problems. See the "ServerGuide problems" on page 60 for more information. v Troubleshooting charts These charts list problem symptoms and steps to correct the problems. See the "Troubleshooting charts" on page 61 for more information. v Diagnostic programs and error messages Real Time Diagnostics tests the major components of your BladeCenter Unit, including the management modules, switch modules, CD-ROM drive, diskette drive, and your blade server, while the server operating system is running.
