    Junos Pulse Gateway Cabinet Requirements

    You can mount the Junos Pulse Gateway (except for the MAG2600) in a cabinet that contains a 19-in rack. Cabinet requirements consist of:

    • Cabinet size
    • Clearance requirements
    • Cabinet airflow requirements

    Table 1 provides the cabinet requirements and specifications for the Junos Pulse Gateway.

    Table 1: Cabinet Requirements and Specifications

    Cabinet Requirement

    Guidelines

    Cabinet size

    • You can mount the Junos Pulse Gateway in a cabinet that contains a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association (http://www.eia.org).

      Note: The rack must meet the strength requirements to support the weight of the Junos Pulse Gateway.

    • The minimum cabinet size must be able to accommodate the maximum external dimensions of the Junos Pulse Gateway.

    Clearance requirements

    • The outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.3 cm).
    • The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between the inside of the front door and the inside of the rear door.

    Cabinet airflow requirements

    When you mount the Junos Pulse Gateway in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

    • Ensure adequate cool air supply to dissipate the thermal output of the Junos Pulse Gateway.
    • Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet without recirculating into the Junos Pulse Gateway. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.
    • Install the Junos Pulse Gateway in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust. This maximizes the clearance for critical airflow.
    • Route and dress all cables to minimize the blockage of airflow to and from the chassis.
    • Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the Junos Pulse Gateway and cabinet.
    • A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.
