SRX110 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 1 provides the details of requirements for rack size, clearance, airflow, spacing of mounting brackets and flange holes, and connecting to the building structure.

Table 1: Rack Requirements for the Services Gateway

Rack Requirement

Specifications

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).

Clearance

  • 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.
