M120 Cabinet Airflow Requirements

When you mount the router in a cabinet, you must ensure that ventilation through the cabinet is sufficient to prevent overheating. Following is a list of requirements to consider when planning for chassis cooling:

• Ensure that the cool air supply you provide through the cabinet can adequately dissipate the thermal output of the router. Router Environmental Specifications lists the router's environmental specifications, including its operating temperature and thermal output.
• Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without recirculating into the router. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust. For an illustration of chassis airflow, see Airflow Through the Chassis.
• Route and dress all cables to minimize the blockage of airflow to and from the chassis.
