M10i 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 Components Industry Association (http://www.ecianow.org/).

With the use of adapters, the router is designed to fit into a 600-mm-wide and 600-mm-deep 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). 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: 8.7 in. (22.1 cm) high, 18 in. (45.7 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the 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.

The chassis height of 8.7 in. (22.1 cm) is approximately 5 U. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Components Industry Association. You can stack eight router in a rack that has at least 40 U (70 in. or 1.78 m) of usable vertical space.

The rack must be strong enough to support the weight of the fully configured router, up to approximately 79 lb (35.8 kg). If you stack eight fully configured routers in one rack, it must be capable of supporting about 632 lb (286.7 kg).
