SRX5800 Services Gateway Rack Size and Strength Requirements

The size, strength, and location of the rack must accommodate the services gateway's weight and external dimensions. The location of the rack must allow for the clearance requirements specified in Clearance Requirements for SRX5800 Services Gateway Airflow and Hardware Maintenance.

The chassis is 17.37 in. (44.11 cm) wide. The services gateway is designed for installation in a standard 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). The spacing of the holes between the left and right front-mounting flanges and center-mounting brackets is 18.31 in (465 mm) apart. However, the inner edge of the rack rails must allow sufficient space for the width of the chassis.

With the use of adapters or approved wing devices to narrow the opening between the rails, the services gateway can fit into a 600-mm-wide rack, as defined in the four-part Equipment Engineering (EE); European telecommunications standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute (http://www.etsi.org).

Observe these guidelines:

  • The rack must have sufficient vertical usable space to accomodate the height of the services gateway: 27.75 in. (70.49 cm) high (approximately 16 U). You can stack three services gateways in a rack that is at least 48 U (89.3 in. or 2.24 m) in height.

    Note: A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment.

  • The location of the rack must provide sufficient space to accomodate the depth of the services gateway. The chassis is 23.0 in. (58.42 cm) deep.
  • The rack must be strong enough to support the weight of the fully configured services gateway, up to 350 lb (158.76 kg). If you stack three fully configured services gateways, it must be capable of supporting up to 1,050 lb (476.3 kg).
