The ambient temperature around the shelf and the air inlet temperature must not
55°C (131°F).
The AXP1440-C07 shelf regulates the fan speed based on the temperature sensors
present in the shelf. The fan speed is adjusted to the lowest speed which still keeps
the evaluated temperature readings below or at their respective upper noncritical
threshold. The fan speed depends on the ambient temperature, blade design,
temperature threshold settings, and shelf configuration.
