Inlet Temperature versus Airflow Requirement in Server

The following tables provide the required airflow rate and airflow speed to the U50/U50 LV card under various operating conditions. In these tables, the term load refers to the total power drawn by the card.

Note: In the following tables, the term load refers to the total thermal power dissipation of the card.
