7.14 Fail Safe Logic and Watchdog Support
The IPMC firmware supports automatic fail safe logic for the payload firmware on the SPP.

with the following settings:

SPP firmware (U-Boot) must disable or reset the BMC Watchdog within 30 seconds of payload
activation. Failure to disable or reset the BMC Watchdog will result in the IPMC performing a
payload reset.
