The Alveo MA35D card is designed for passive cooling and requires an external mechanism to ensure proper airflow for cooling. The card supports bidirectional airflow which includes normal (forward) airflow direction from retainer bracket to I/O bracket and reverse airflow, as illustrated in the following figure. Passive cards should not be powered without a forced airflow mechanism in place.
