POST beep codes If Power-On Status is set to [Enabled], POST also generates beep codes to indicate successful completion or the detection of an error. The startup of the operating system or application program indicates successful completion of POST. More than one beep indicates that POST detected an error. For a list of beep codes, see "Symptom-to-FRU index" on page 160. Error messages 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 indicated by error messages should be performed by a trained service technician. Hardware error messages that occur can be text, numeric, or both. Messages generated by the software generally are text messages, but they also can be numeric. POST error messages and beep codes: POST error messages and beep codes occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. POST error messages are 3-, 4-, 5-, 8-, or 12-character alphanumeric messages and include brief explanations (except I999XXXX errors). For a list of error codes, see "Symptom-to-FRU index" on page 160. SCSI error messages : These messages appear if a problem or conflict is detected by the SCSI subsystem. Refer to the SCSI documentation in the ServerGuide package that comes with the server for information about these messages. Diagnostic error messages : Diagnostic error messages occur when a test finds a problem with the server hardware. The messages present text information that can be used to identify a failing part. These error messages are alphanumeric. Follow the instructions on the screen. For a list of diagnostic codes, see "Symptom-to-FRU index" on page 160. IBM Netfinity 3000 - Type 8476 9
