Error Code Error Message
A003 TPM device failed self test.
A100 BIOS ACM Error
A421 PCI component encountered a SERR error
A5A0 PCI express* component encountered a PERR error
A5A1 PCI express* component encountered an SERR error

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 on error conditions. The beep code is followed by a user-visible code on the
POST Progress LEDs.

The following Beep Codes are sounded during BIOS Recovery.
2 Recovery started
4 Recovery failed
The Integrated 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.
Codes that are common across all Intel server boards and systems that use same generation chipset are
listed in the following table. Each digit in the code is represented by a sequence of beeps whose count is
equal to the digit.
Code Associated Sensors
1-5-2-1 No CPUs installed or first CPU socket is empty.
1-5-2-4 MSID Mismatch
1-5-4-2 Power fault
1-5-4-4 Power control fault (power good assertion timeout).

Table 66. Integrated BMC Beep Codes

Description
Short beep sounded whenever USB device is discovered in
POST, or inserted or removed during runtime.
System halted because Intel® Trusted Execution Technology
detected a potential violation of system security.
System halted because a fatal error related to the memory
was detected.
System halted because a fatal error related to the CPU
family/core/cache mismatch was detected.
Recovery boot has been initiated.
Recovery has failed. This typically happens so quickly after
recovery is initiated that it sounds like a 2-4 beep code.
Reason for Beep
CPU1 socket is empty, or sockets are populated incorrectly
CPU1 must be populated before CPU2.
MSID mismatch occurs if a processor is installed into a system
board that has incompatible power capabilities.
DC power unexpectedly lost (power good dropout) – Power
unit sensors report power unit failure offset
Power good assertion timeout – Power unit sensors report soft
power control failure offset
VR controller DC power on sequence was not completed in
time.
The system does not power on or unexpectedly powers off
and a Power Supply Unit (PSU) is present that is an
incompatible model with one or more other PSUs in the
system.
