Configures PCI adapters Starts the video operation Verifies that drives (such as the diskette, CD-ROM, and hard disk drives) are connected properly 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. While the memory is being tested, the amount of available memory appears on the screen. These numbers advance as the server progresses through POST and the final number that appears on the screen represents the total amount of memory available. If POST finishes without detecting any problems, a single beep sounds, the first screen of the operating system or application program appears, and the System POST Complete (OK) light is illuminated on the information LED panel. If POST detects a problem, more than one beep sounds and an error message appears on the 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. For a list of error codes and messages, see "Symptom-to-FRU index" on page 285. 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 a list of error codes and messages, see "Symptom-to-FRU index" on page 285. Error messages - descriptions 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 the software generally are text messages, but they also can be numeric. 12 Netfinity Server HMM
