Exception Codes
In case of an error, the BMC drives a blinking code on the blue Status LED (LED1). The same error code is also
reported by the BMC Flags register. The Exception Code is not stored in the Flash Storage and is cleared when the
power is removed. Therefore, a “Clear Exception Code” command is not needed or supported.
