Temperature has reached a destructive level. Device might be damaged.
Most ATCA chassis react to temperature events in the following manner: When a minor threshold is reached,
the shelf manager will incrementally increase airflow (fan speed) to bring the temperature below the crossed
threshold. When a major threshold is reached, the shelf manager will increase the fans to maximum speed.
When a critical threshold is reached, the shelf manager will shutdown the blade to prevent damage. The shelf
alarm panel, when available, can inform the operator with LEDs when an alarm (minor, major, critical) is
raised. Refer to your chassis documentation to adapt and optimize your temperature monitoring application
to chassis capabilities. See also System Airflow section for more information.
Below is the list of temperature sensors with their respective thresholds.
