Thermal shutdown
The adapter card includes an overtemperature overheat protection. The BMC will automatically shut down the card if a PCIe switch
temperature beyond 105°C (221°F) or a FireFly temperature beyond 70 °C (158°F) is detected. The automatic shutdown can be disabled
by setting DIP-Switch OPT6.
NOTE:
The adapter card link LEDs will start flashing yellow when a PCIe switch temperature of 95°C (203°F) is reached or when FireFly
reports a temperature of 60°C (14°F).
NOTE:
The automatic shutdown can be disabled by setting DIP-Switch OPT6. Prior to disabling the automatic shutdown, please ensure
you have established proper airflow.
