Rack Size and Strength
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
Industry Association (
With the use of adapters or approved wing devices to narrow the opening between the
rails, the router fits into a 600-mm-wide rack or cabinet , as defined in the four-part
Equipment Engineering (EE); European telecommunications standard for equipment practice
(document number ETSI EN 300 119) published by the European Telecommunications
Standards Institute
).
The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 14.0 in. (356 mm) high, 24.5 in. (622 mm) deep, and
17.45 in. (443 mm) wide. The spacing of rails and adjacent racks must also allow for the
clearances around the router and rack that are specified in
Requirements for Airflow and Hardware Maintenance” on page 56
