Intel Servers - Reading the BEEP Codes – Catapult Thunder Support

How to read the BEEP codes reported by server on boot.

POST Error Beep Codes

Beeps	Error Message	POST Progress Code	Description
1 short	USB device action	N/A	Short beep sounded whenever USB device is discovered in POST, or inserted or removed during runtime.
1 long	Intel® TXT security violation	AE, AF	System halted because Intel® Trusted Execution Technology detected a potential violation of system security.
3 short	Memory error	Multiple	System halted because a fatal error related to the memory was detected.
3 long and 1 short	CPU mismatch error	E5, E6	System halted because a fatal error related to the CPU family/core/cache mismatch was detected.
2 short	BIOS recovery started	N/A	Recovery boot has been initiated.
4 short	BIOS recovery failed	N/A	Recovery has failed. This typically happens so quickly after recovery is initiated that it sounds like a 2-4 beep code.

Integrated BMC beep codes

Code	Associated Sensors	Reason for Beep
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.
1-5-2-2	CPU CAT Error (IERR) assertion	CPU encountered an error while initializing.
1-5-2-3	CPU ERR2 timeout assertion	CPU Failed to initialize in the specified time for the system.
1-5-2-4	MSID mismatch.	MSID mismatch occurs if a processor is installed into a system board that has incompatible power capabilities.
1-5-2-5	CPU population error	CPU1 socket is empty, or 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 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.
