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 for cooling the
system is within the thermal
specifications for the system (typically
below 35°C).
