T320 Router Installation Summary on page 107
The T320 Core Router can be installed many types of racks, including four-post racks or
cabinets and open-frame racks. An example of an open-frame rack appears in
Figure 32 on page 91.
The router is designed for installation in a 19-in. rack as defined in Cabinets, Racks, Panels,
and Associated Equipment (document number EIA-310-D) published by the Electronics
Components Industry Association (
With the use of adapters, the router is designed to fit into a 600-mm-wide 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 (
Use approved wing devices to narrow the opening between the rails.
The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 25.13 in. (63.82 cm) high, 31.4 in. (79.8 cm) deep, and 17.43 in.
(44.3 cm) wide. The outer edges of the front-mounting flanges and center-mounting
brackets extend the width to 19 in. (48.3 cm). The spacing of rails and adjacent racks
must also allow for the clearances around the router and rack that are specified in
Clearance Requirements for Airflow and Hardware Maintenance" on page
The chassis height of 25.13 in. (63.82 cm) is approximately 14.4 U. A U is the standard
