2.6 Power-On Self Test (POST)
The BIOS indicates the current testing phase during POST by writing a hex code to
the Enhanced Diagnostic LEDs, located on the rear of the server main board and
visible through the back of the chassis.
If errors are encountered, error messages or codes will either be displayed to the
video screen, or if an error has occurred prior to video initialization, errors will be
reported through a series of audible beep codes. POST errors are logged in to the
System Event Log (SEL).
During the power-on self test (POST), the server may indicate a system fault by:
■Displaying error codes and messages at the display screen
■Beeping the speaker in a coded sequence
■Illuminating the POST LEDs, visible from the rear panel, in a coded fashion
2.6.1 POST Screen Messages
During POST, if an error is detected, the BIOS displays an error code and message to
the screen. The tables in this section describe the standard and extended POST error
codes and their associated messages. The BIOS prompts the user to press a key in
case of serious errors. Some of the error messages are preceded by the string “Error”
to highlight the fact that the system may be malfunctioning. All POST errors and
warnings are logged in the System Event Log (SEL) unless it is full.
Note – All POST errors are logged to the SEL, which is capable of holding
approximately 3200 entries. After the SEL is full, no further errors are logged. The
SEL can be cleared using the SSU or the BIOS setup. The SEL is automatically
cleared after running the PCT.
Table2-9 and Table 2-10 contain the POST error messages and error codes.
