2.2. Recovering After Auto-Shutdown
The Board Management Controller holds power off until the next power cycle. Therefore, when an Intel® FPGA PAC card power is shut down, you must power cycle the server to return power to the Intel® FPGA PAC.
The common cause of power shutdown is the FPGA overheating (when the core temperature is over 100°C), or the FPGA drawing excessive current. This typically happens when the AFU design exceeds the Intel® FPGA PAC defined power envelopes or there is insufficient airflow. In this case, you must reduce power consumption in your AFU.
