The Alveo U45N accelerator card support airflow in either direction.
Figure 1. Airflow Direction for U45N Accelerator Card
The following table shows requirements for the Alveo U45N accelerator card that are dependent on airflow direction.
|QSFP case temperature for airflow entering PCIe bracket||QSFP (≤ 2.5W) case should be rated 70°C|
|QSFP case temperature for airflow exiting PCIe bracket||QSFP (≤ 2.5W) case should be rated 85°C|
|Airflow entering PCIe bracket area||104.6 mm x 13.2 mm|
|Airflow exiting PCIe bracket area||98.4 mm x 20.3 mm|
