The Services Router is designed for installation in a rack that complies with either of the following standards:
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: 3.44 in. (8.74 cm) high, 17.44 in. (44.3 cm) wide, and 21.13 in. (53.67 cm) deep.
The outer edges of the mounting ears extend the width of either chassis to 19.44 in. (48.38 cm), and the front of the chassis extends approximately 0.5 in. (1.27 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.)
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.
The J4350 and J6350 chassis height of 3.44 in. (8.74 cm) equals 2 U. Each U is a standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.
