Appendix A
BIOS Error Beep Codes
During the POST (Power-On Self-Test) routines, which are performed each time
the system is powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue the
boot-up process. The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up pro-
cedure. If a fatal error occurs, you should consult with your system manufacturer
for possible repairs.
These fatal errors are usually communicated through a series of audible beeps.
The numbers on the fatal error list, on the following page, correspond to the number
of beeps for the corresponding error. All errors listed, with the exception of Beep
Code 8, are fatal errors.
POST codes may be read on the debug LEDs located beside the LAN port on the
serverboard backplane. See the description of the Debug LEDs (LED1 and LED2)
in Chapter 5.
