    Junos Pulse Gateway Rack Requirements

    The Junos Pulse Gateway can be installed in a rack. Many types of racks are acceptable, including front-mount racks and four-post (telco) racks.

    Rack requirements consist of:

    • Rack size
    • Mounting bracket hole spacing
    • Rack connection to the building structure

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

    Table 1: Junos Pulse Gateway Rack Requirements

    Rack Requirements

    Specifications

    Rack type

    Use a two-post rack or a four-post rack. You can mount the Junos Pulse gateway on any two-post or four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in./4.45 cm) increments and that meets the size and strength requirements to support the weight.

    A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association (http://www.eia.org).

    The rack must meet the strength requirements to support the weight of the chassis.

    Rack Size

    A 19 in. (48.3 cm) 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).

    Rack Requirements

    • The outer edges of the mounting brackets extend the width of either chassis to 19 in. (48.3 cm).
    • The front of the chassis extends approximately 0.5 in. (1.27 cm) beyond the mounting ears.
    • Maximum permissible ambient temperature when two devices are placed side by side in a 19 in. rack is 40°C.

    Spacing of Mounting Bracket and Flange Holes

    • The holes within each rack set are spaced at 1 U [1.75 in. (4.5 cm)]. The device can be mounted in any rack that provides holes or hole patterns spaced at 1-U [1.75 in. (4.5 cm)] increments.
    • The mounting brackets and front-mount flanges used to attach the chassis to a rack are designed to fasten to holes spaced at rack distances of 1 U (1.75 in.).
    • The mounting holes in the mounting brackets provided with the device are spaced 1.25 in. (3.2 cm) apart (top and bottom mounting hole).

    Connecting to the Building Structure

    Always secure the rack in which you are installing the services gateway to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.
