Figure 3-143 Back-to-front airflow for port-side intake

The airflow direction of the power modules and fan modules required on the CloudEngine 6800 series switches depends on how the device is installed in a cabinet. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If a switch is installed with the power supply side facing the front and the port side facing the back, the switch needs to adopt fan modules and power modules with front-to-back airflow.
