The power supply provides FRU-to-port or port-to-FRU airflow depending on the product
SKU you purchase. On legacy switches, or switches with an LCD, this airflow is called
back-to-front and front-to-back. The power supplies either have labels on the handles
that indicate the direction of airflow or they have color-coded handles with a fan icon.
See Figure 33 on page 54 for an example of the power supply. Either a power supply has
the label or a blue handle, which denotes FRU-to-port airflow. A power supply with
AFI
the label or a gold-colored handle denotes port-to-FRU airflow.
