Airflow and Power Supply Compatibility

The EX4650 series offers different airflow and power supply configurations to suit various data centre environments. The EX4650-48Y-AFO model specifically supports front-to-back airflow with AC power supplies labeled "AIR OUT" (AFO). It's crucial to ensure that all components (fans and power supplies) match in airflow direction to maintain optimal cooling and prevent system alarms .
