Environment and Cooling

The Add-on modules operates in an ambient temperature range of 0°C (32°F) to 45°C (113°F). The modules can tolerate atmospheric pollution degree 2—only dry, non-conductive pollution is acceptable. Therefore, it is recommended that the cards be mounted in a suitable enclosure.

As you add modules, you must ensure that there are no hot spots created in the board stack due to airflow impairment.

Airflow impairment might result from cables coming in the way or lack of fan direction towards the stack. Record the temperature in several places (especially around I/O and DSP locations) to ensure even heat flow. Impaired heat flow might cause malfunctions and eventually lead to permanent loss of function.
