SRX220 Services Gateway Cabinet Requirements
The SRX220 Services Gateway can be installed in a standard 800 mm
(31.5 in.) or larger enclosed cabinet. Table 1 provides the details on
cabinet size, clearance, and airflow requirements.

Requirements
Cabinet Requirements | Specifications |
|---|
Cabinet size | 19 in. (48.3 cm) as defined in Cabinets,
Racks, Panels, and Associated Equipment (document number
EIA-310-D) published by the Electronics Industry Association (http://www.eia.org). You can mount the services gateway horizontally in the cabinet. |
Clearance requirements | The cabinet is at least 1 U (1.75 in. or 4.5 cm)
high. The outer edges of the mounting brackets extend the width
of the chassis to 19 in. (48.3 cm), and the front of the
chassis extends approximately 0.5 in. (1.27 cm) beyond the
mounting brackets. 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.
Note:
The holes for the mounting brackets are spaced 1.25 in.
(3.2 cm) apart, measured from the center of the hole. |
Cabinet airflow requirements | Ensure that ventilation through the cabinet is sufficient
to prevent overheating. Ensure adequate cool air supply to dissipate the thermal
output of the device. 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.
Note:
A cabinet larger than the minimum size required provides
better airflow and reduces the chance of overheating. |
