MX2020 Cabinet Airflow Requirements

Before you install the router in a cabinet, you must ensure that ventilation through the cabinet is sufficient to prevent overheating. Consider the following requirements to 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.

  • 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 Figure 1.

  • Install the router as close as possible to the front of the cabinet so that the cable manager just clears the inside of the front door. This maximizes the clearance in the rear of the cabinet for critical airflow.

  • Route and dress all cables to minimize the blockage of airflow to and from the chassis.
