Diagnostic tools overview 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 more information about what caused an error message to appear and what action to take, see "Power-on self-test (POST) messages" on page 165 and "POST message table" on page 169. Also see "Power-on self-test (POST) beep codes" on page 192. 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 your 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. Software-generated error messages These messages occur if a problem or conflict is found by an application program, the operating system, or both. Error messages for operating-system and other software problems are generally text messages, but they also can be numeric messages. For information about these software error messages, refer to the information that comes with the operating system or application program, or both. Troubleshooting charts The charts under "Troubleshooting charts" on page 200 list symptoms of problems (for example, a symptom might be "The mouse is not working."), along with steps to correct the problems. 162 Netfinity 3000 User's Handbook
