If POST finishes without detecting any problems, a single beep sounds, and the first screen of the operating system or application program appears. If POST detects a problem, more than one beep sounds, and an error message appears on the screen. See "Beep symptoms" on page 79 and "POST error codes" on page 95 for more information. Notes: 1. If you have a power-on password or administrator password set, you must type the password and press Enter, when prompted, before POST will continue. 2. A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the test. The POST error log contains the three most recent error codes and messages that the system generated during POST. The System Error log contains all messages issued during POST and all system status messages from the service processor. You can view the contents of the System Error log from the Configuration/Setup Utility program or from the diagnostic programs. Viewing error logs from the Configuration/Setup Utility program Start the Configuration/Setup Utility program and select Error Logs from the main menu; then, select either POST Error Log or System Event/Error Log. See "Using the Configuration/Setup Utility program" on page 9 for more information. Viewing error logs from the diagnostic programs Start the diagnostic programs; select Hardware Info from the top of the diagnostic programs screen; select System Error Log from the list that appears; then, follow the instructions on the screen. See "Starting the diagnostic programs" for more information. Diagnostic programs and error messages The server diagnostic programs are stored in upgradeable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server. Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel. Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears. Starting the diagnostic programs Complete the following steps to start the diagnostic programs: 1. Turn on the server and watch the screen. Note: To run the diagnostic programs, you must start the server with the highest level password that is set. That is, if an administrator password is 22 xSeries 335 Type 8676, Type 8830: Hardware Maintenance Manual and Troubleshooting Guide
