If you have a power-on password or administrator password set, you must type the password and press Enter before POST will continue. If POST finishes without detecting any problems, a single beep sounds and the first screen of your operating system or application program appears. If POST detects a problem, more than one beep sounds and an error message appears on your screen. Note A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages usually will not occur the next time you run the test. POST Beep Codes: POST generates beep codes to indicate successful completion or the detection of a problem. One beep indicates the successful completion of POST. More than one beep indicates that POST detected a problem. For more information, see "Beep Symptoms" on page 182. 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 trained service personnel. Hardware error messages that occur can be text, numeric, or both. Messages generated by your software generally are text messages, but they also can be numeric. POST Error Messages: POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. For a list of POST errors, see "POST Error Codes" on page 195. System Monitoring Messages: System monitoring messages occur as the Advanced Remote Management Controller monitors critical system functions. For a list of codes, see "System Management Codes" on page 208. 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 in the Test Log. For a list of diagnostic error codes, see "Diagnostic Error Codes" on page 187. 10 Netfinity Server HMM
