Cabinet Airflow Requirements

When you mount the SRX 210 services gateway in a cabinet, you must ensure that ventilation through the cabinet is sufficient to prevent overheating. The requirements to consider when planning for chassis cooling are as follows:

• Ensure that the cool air supply you provide through the cabinet can adequately dissipate the thermal output of the device.
• Ensure that the cabinet allows the hot exhaust air from the chassis to exit from the cabinet without recirculating into the device. 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 x on page x.

• Install the device as close as possible to the front of the cabinet so that the cable management system clears the inside of the front door. Installing the chassis close to the front of the cabinet 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.
