Beep Codes
One beep and the appearance of text on the monitor indicates
successful completion of POST. More than one beep indicates that
POST detects an error.
Beep codes are sounded in a series of two or three sets of beeps.
The duration of each beep is constant, but the length of the pause
between the beeps varies. For example, a 1–2–4 beep code sounds
like one beep, a pause, two consecutive beeps, another pause, and
four more consecutive beeps.
It is possible to misinterpret a beep code if you do not understand
exactly how they work. Keeping in mind that POST error codes
vary in the length of the pause, and not the duration of the beep
tones, will help you to distinguish the beeps.
The following list contains more detailed descriptions of the possible
types of beeps that your server might emit.
Beep Descriptions
Beep Type
Meaning
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.
