When the switch is powered on for the first time, use the
fan prefer-direction
command to configure
the airflow direction of the fan tray as the preferred airflow direction of the switch. If the fan tray
airflow direction and the preferred airflow direction are not the same, the system generates traps and
logs. By default, the preferred airflow direction is from the power module side to the port side.

fan prefer-direction
command, see
