Exception Blink Codes
In the case of an error, the BMC shows a blink code on the STATUS-LED. This 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, the “Clear Exception Code” command is not
supported.
Table 4-2: BMC Exception Blink Codes
BMC Flags
The BMC Flags Register returns the last detected exception code since power up.

Watchdog Timer
The BMC Watchdog activation is caused by under voltage protection. The Watchdog LED gets
flashed after restart but only if the power supply reaches 4.2V.
