SRX110 Services Gateway Cabinet Requirements

 

The services gateway can be installed in a standard 31.5-in. (80.0-cm) or larger enclosed cabinet.

Table 1 provides the details on cabinet size, clearance, and airflow requirements.

Cabinet Requirement

Specifications

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

  • 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. (48.2 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 for the chassis are spaced 1.25 in. (3.2 cm) apart, measured from the center of the hole.

Airflow

  • Ensure that ventilation through the cabinet is sufficient to prevent overheating.

  • Ensure that cool air supply is adequate 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 at 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 size provides better airflow and reduces the chance of overheating.
