For a list of error codes and messages, see "Symptom-to-FRU index" on page 285. Diagnostic error messages: Diagnostic error messages occur when a test finds a problem with the server hardware. These error messages are alphanumeric and they are saved temporarily in the Test Log and logged in the System Error Log when diagnostics are run. For a list of error codes and messages, see "Symptom-to-FRU index" on page 285. Software-generated error messages: These messages occur if a problem or conflict is found by an application program, the operating system, or both. Messages are generally text messages, but they also can be numeric. For information about these error messages, refer to the documentation that comes with the software. System error log The System Error Log contains all error and warning messages issued during POST and all system status messages from the Netfinity Advanced System Management Processor. See "System error log" on page 31 for information about how to view the System Error Log. Option diskettes An optional device or adapter might come with an Option Diskette.
