BMC Error Codes

The BMC may generate beep codes upon detection of failure conditions. Beep codes are sounded
each time the problem is discovered (for example, on each power-up attempt) but are not sounded
continuously. Common supported codes are listed in
In Table D-1, each digit in the code is represented by a sequence of beeps whose count is equal to
the digit.
Table D-1 BMC Beep Codes
Beep Code Reason for Beep
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: DC power is unexpectedly
lost (power good dropout).
1-5-4-4 Power control fault (power good assertion
timeout).
1-5-1-2 VR Watchdog Timer sensor assertion
1-5-1-4 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.
