Table 12: SRX100 Services Gateway Cabinet Requirements
Specifications
Cabinet
Requirements
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 gateway horizontally in the cabinet.
Cabinet size
•
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 either 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 chassis are spaced 1.25 in. (3.2
cm) apart, measured from the center of the hole.
Clearance
requirements
•
Ensure sufficient 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 required provides better airflow
and reduces the chance of overheating.

SRX100 Services Gateway Rack Requirements
The services gateway can be installed in a rack. Many types of racks are acceptable,
including front-mount racks and four-post (telco) racks.
NOTE: The services gateway cannot be center mounted in a rack.
Table 13 on page 27 provides the details of requirements for rack size, clearance, airflow,
spacing of mounting brackets and flange holes, and connecting to the building structure.
