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.

Error Message
POST Progress Code
Description
1
USB device action
NA
Short beep sounded whenever a USB device is discovered
in POST, or inserted or removed during runtime
1 long
Intel
®
TXT security
violation
0xAE, 0xAF
System halted because Intel
®
Trusted Execution
Technology detected a potential violation of system
security.
3
Memory error
See Tables 28 and 29
System halted because a fatal error related to the memory
was detected.
3-long
and 1
CPU mismatch
error
0xE5, 0xE6
System haled because fatal error related to the CPU
family/core/cache mismatch was detectived
2
BIOS Recovery
started
NA
Recovery boot has been initiated
4
BIOS Recovery
failure
NA
BIOS recovery has failed. This typically happens so quickly
after recovery us initiated that it sounds like a 2-4 beep
code.
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.
Table 67. Integrated BMC Beep Codes
Code
Reason for Beep
Associated Sensors
1-5-2-1 No CPUs installed or first CPU socket is
empty.
CPU1 socket is empty, or sockets are populated
incorrectly
CPU1 must be populated before CPU2.
1-5-2-4 MSID Mismatch
MSID mismatch occurs if a processor is installed
into a system board that has incompatible power
capabilities.
1-5-4-2 Power fault
DC power unexpectedly lost (power good
dropout) – Power unit sensors report power unit
failure offset
1-5-4-4 Power control fault (power good
assertion timeout).
Power good assertion timeout – Power unit
sensors report soft power control failure offset
1-5-1-2 VR Watchdog Timer sensor assertion
VR controller DC power on sequence was not
completed in time.
1-5-1-4 Power Supply Status
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.
