SRX345 Services Gateway Rack Size and Strength Requirements
When installing the services gateway in a rack, you must ensure that the rack complies
with a 1U (19 in. or 48.7 cm) rack as defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310-D), published by the Electronic Industries Alliance
(http://www.ecaus.org/eia/site/index.html).
When selecting a rack, ensure that the physical characteristics of the rack comply with
the following specifications:
•
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.

SRX345 Services Gateway Spacing of Mounting Brackets and Flange Holes
The spacing of the mounting brackets and flange holes on the rack and device mounting
brackets are as follows:
•
The holes within each rack set are spaced at 1 U (1.75 in. or 4.5 cm).
•
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).
