2.1. Auto-Shutdown

The Board Management Controller monitors and controls resets, different power rails, FPGA and board temperatures. When the Board Management Controller senses conditions that can potentially damage the board, it automatically shuts down board power for protection.
Note: When the FPGA loses power, the PCIe link between the Intel® FPGA PAC and host is down. In many systems, the PCIe link-down may cause a system crash.
Table 2.  Auto-Shutdown CriteriaThe following table lists the criteria beyond which the Board Management Controller shuts down board power.
