SRX1400 Services Gateway Cabinet Requirements

 

This topic includes the following sections:

Cabinet Size and Clearance Requirements

The minimum size cabinet that can accommodate the services gateway is 27.5 in. (69.8 cm) wide and 31.5 in. (80.0 cm) deep. The cabinet must allow at least 5 in. (13 cm) of clearance on each side of the chassis to allow for cooling air to flow through the vents on each side of the device. A cabinet larger than the minimum requirement provides better airflow and reduces the chance of overheating.

Allow at least 3 in. (7.6 cm) of vertical clearance between the top and bottom of the services gateway and other devices in the cabinet.

If you provide adequate cooling air and airflow clearance, you can stack eight devices in a cabinet that has at least 40 U (70 in. or 1.78 m) of usable vertical space.

Cabinet Airflow Requirements

When you mount the services gateway in a cabinet, you must ensure that ventilation through the cabinet is sufficient to prevent overheating. Consider the following requirements when planning for chassis cooling:

  • Ensure that the cool air supply you provide through the cabinet can adequately dissipate the thermal output of the services gateway.

  • Allow at least 3 in. (7.6 cm) of vertical clearance between the top and bottom of the services gateway and other devices in the cabinet.

  • Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without recirculating into the services gateway. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis.

  • Ensure that the cabinet provides at least 13 cm (5 in) of clearance on each side of the chassis for cooling airflow.

  • If the cabinet contains a top or doors, you must provide perforations in these elements to allow adequate airflow through the cabinet to dissipate the heat generated by all of the devices in the cabinet.

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