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)
The horizontal spacing between the rails in a rack that complies with this standard
is wider than the appliance’s mounting brackets, which measure 19 in. (48.3 cm)
from outer edge to outer edge. Use approved wing devices to narrow the opening
between the rails as required
•The rack rails must be spaced wide enough to accommodate the external dimensions
of the JA2500 appliance chassis. The shipping dimensions of a JA2500 appliance are
17.81 in. x 17.31 in. x 3.5 in. (45.2 cm x 44 cm x 8.89 cm).
•The outer edges of the mounting brackets extend the width of the chassis to 19 in.
(48.3 cm).
•The front of the chassis extends approximately 0.5 in. (1.27 cm) beyond the mounting
ears.
•The holes within each rack set are spaced at 2-U [3.5 in (8.9 cm)]. Therefore, the
appliance can be mounted in a rack that provides holes or hole patterns spaced at 2-U
[3.5 in (8.9 cm)] increments, or in a rack that provides holes or hole patterns spaced
at 1-U [1.75 in. (4.5 cm)] increments as long as there is 2x1-U space available in the
rack.
•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 2-U [3.5 in (8.9 cm)]
increments, or in a rack that provides holes or hole patterns spaced at 1-U [1.75 in.
(4.5 cm)] increments as long as there is 2x1-U space available in the rack.
•The mounting holes in the mounting brackets provided with the device are spaced
1.25 in. (3.2 cm) apart (top and bottom mounting holes).
•Always secure the rack in which you are installing the appliance to the structure of the
building. If your geographical area is subject to earthquakes, bolt the rack to the floor.
