74 Using the System Setup Program
Emergency Throttling Press to configure the compute sled and chassis
emergency throttle functions.
This option sets the policy to take effect when the sled
detects a system emergency failure (such as fan error,
chassis critical power events, PSU critical power events,
abnormal ambient temperature, etc.).
NOTE: The FCB initiates emergency throttling when active
power supplies do not meet the maximum PSU configurations
or when the exhaust temperature control PWM output is
above 100%.
