AMD Solarflare X4522 Ethernet adapters support airflow in either direction:
- Normal flow, where airflow is out from the I/O bracket.
- Reverse flow, where airflow is into the I/O bracket.

The following table shows requirements for
AMD Solarflare
X4522 Ethernet adapters that are dependent on
airflow direction.
