No Beeps
If no beeps occur after your server successfully
completes POST, your server might contain a
defective system board, a defective speaker, or a
disconnected speaker.
One Short Beep
If this occurs after your server successfully completes
POST, then POST has no configuration or functional
errors to report. One beep also occurs if you enter an
incorrect power-on password.
Two Short Beeps
This beep combination indicates that POST
encountered an error.
Three Short Beeps
This beep combination indicates a system memory
error. This combination occurs only if the video BIOS
cannot display the error code.

This beep type indicates that your server system
board or speaker subsystem might contain a failing
component.
