Rack Requirements
J-series Services Routers must be installed in a rack. Many types of racks are
acceptable, including front-mount racks, four-post (telco) racks, and center-mount
racks.
The following sections describe rack requirements:
■ Rack Size and Strength for J2320 and J2350 Routers on page 104

Rack Size and Strength for J2320 and J2350 Routers
The J2320 and j2350 Services Routers are designed for installation in a rack that
complies with either of the following standards:
■ A 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)
■ A 600-mm 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)
The horizontal spacing between the rails in a rack that complies with this standard
is usually wider than the router's mounting ears, which measure 19 in. (48.2 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 widely enough to accommodate the router chassis's
external dimensions:
■ J2320 chassis—1.75 in. (4.45 cm) high, 17.51 in. (44.48 cm) wide, and 15.1 in.
(38.35 cm) deep.
■ J2350 chassis—2.61 in. (6.63 cm) high, 17.51 in. (44.48 cm) wide, and 15.1 in.
(38.35 cm) deep.
The outer edges of the mounting ears extend the width of either chassis to 19 in.
(48.2 cm), and the front of the chassis extends approximately 0.78 in. (1.98 cm)
beyond the mounting ears. The spacing of rails and adjacent racks must also allow
for the clearances around the router and rack. (See “General Site
Guidelines” on page 103.)
CAUTION: If you are mounting the router in a cabinet, be sure that ventilation is
sufficient to prevent overheating.
If a front-mount rack is used, we recommend supporting the back of the router with
a shelf or other structure.
