POST Error Beep Codes
The following table lists the POST error beep codes. Prior to system video initialization, the
BIOS uses these beep codes to inform users of error conditions. The beep code is followed by a
user-visible code on the POST Progress LED’s.
Table 128. POST Error Beep Codes
Beeps Error Message POST Progress Code Description
3 Memory error Multiple System halted because a fatal error related to the memory was
detected.
The BMC may generate beep codes upon detection of failure conditions. Beep codes are
sounded each time the problem is discovered, such as on each power-up attempt but are not
sounded continuously. Each digit in the code is represented by a sequence of beeps whose
count is equal to the digit.

1-5-2-1 CPU: Empty slot / Population error CPU sockets are populated incorrectly – CPU1
must be populated before CPU2.
1-5-4-2 Power fault: DC power unexpectedly lost (power good dropout). Power unit – power unit failure offset.
1-5-4-4 Power control fault (power good assertion timeout). Power unit – soft power control failure offset.
