OK
An upper non-critical
or critical temperature
threshold has been
crossed.
1. Check for clear and unobstructed airflow into and out of the chassis.
2. Ensure the SDR is programmed and correct chassis has been selected.
3. Ensure there are no fan failures.
4. Ensure the air used to cool the system is within the thermal specifications for the system
(typically below 35°C).
