SRX3400 Services Gateway Cabinet Size and Clearance Requirements

The minimum size cabinet that can accommodate the services gateway is 19 in. (48.2 cm) wide and 31.5 in. (80.0 cm) deep. A cabinet larger than the minimum requirement provides better airflow and reduces the chance of overheating. To accommodate a single services gateway, the cabinet must be at least 13 rack units (U) high. If you provide adequate cooling air and airflow clearance, you can stack eight services gateways in a cabinet that has at least 40 U (70 in. or 178 cm) of usable vertical space.

The minimum front and rear clearance requirements depend on the mounting configuration you choose. The minimum total clearance inside the cabinet is 30.7 in. (78 cm) between the inside of the front door and the inside of the rear door.
