SRX1400 Services Gateway Rack Size and Strength Requirements

The SRX1400 Services Gateway can be installed in a rack. Many types of racks are acceptable, including four-post (telco) racks and open-frame racks.

You can front-mount or rear-mount the services gateway in a two-post rack, a four-post rack, or a cabinet.

Note: Though two-post front mounting is most common method of installation for the SRX1400 device, you can also front-mount or rear-mount the chassis in a four-post rack. However, there is no support shelf provided for the rear edge of the chassis to rest.

The device is designed for installation into a 19-in. (48.26 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).

With the use of adapters, the device is designed to fit into a 600-mm-wide (23.62-mm) rack or cabinet, 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). Use approved wing devices to narrow the opening between the rails.

The rack rails must be spaced widely enough to accommodate the device chassis's external dimensions: 5.25 in. (13.3 cm) high, 13.8 in. (35.05 cm) deep, and 17.5 in. (44.5 cm) wide. The spacing of rails and adjacent racks must also allow for the clearances around the device and rack.

The chassis height of 5.25 in. (13.3 cm) is approximately 3 U. 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. You can stack eight SRX1400 Services Gateways in a rack that has at least 40 U (70 in. or 1.78 m) of usable vertical space.

The rack must be strong enough to support the weight of the fully configured device, up to 42.3 lb (19.3 kg). If you stack 8 fully configured devices in one rack, it must be capable of supporting up to 341 lb (155 kg)

SRX1400 Services Gateway Spacing of Mounting Bracket Holes

The device can be mounted in any rack that provides holes or hole patterns spaced at
1 U (1.75 in. or 4.4 cm) increments. The mounting brackets used to attach the chassis to a rack are designed to fasten to holes spaced at those distances.

Connecting the SRX1400 Services Gateway to the Building Structure

Always secure the rack 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. For more information, see Rack-Mounting Requirements and Warnings.
