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 (
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
( ). 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 340.61 lb (154.4 kg)
