SRX5800 Services Gateway Cabinet Size and Clearance Requirements
The minimum size cabinet that can accommodate the device is 600 mm wide and 800 mm deep. A cabinet larger than the minimum requirement provides better airflow and reduces the chance of overheating. To accommodate a single device, the cabinet must be at least 16 U high. If you provide adequate cooling air and airflow clearance, you can stack three devices in a cabinet that has at least 48 U (84 in. or 2.13 m) 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. between the inside of the front door and the inside of the rear door.
