Note: Your SAS Expander Card requires adequate airflow to operate reliably. The
recommended airflow is 200 LFM (linear feet per minute) minimum, to avoid operating
above the maximum ambient temperature. Additionally, when chassis mounting the
SAS Expander Card with screws (rather than installing in a PCIe slot), airflow must run
horizontal to the fins of the heat sink. Forced airflow is required. Contact Adaptec
Support for more information about the chassis mount option.
