Rack Size and Strength

The MX2010 router is 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 Components Industry Association (http://www.ecianow.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 (ETSI). The horizontal spacing between the rails in a

rack that complies with this standard is usually wider than the mounting brackets, which measure

19.2 in. (48.8 cm) from the outer edge to outer edge. Use approved wing devices to narrow the opening

between the rails as required.

A 23-in. rack using appropriate 23-in. to 19-in. rack adapters and an appropriate installation shelf that

supports the chassis at the correct vertical position to properly line up the rack mount holes. Juniper

Networks does not supply this hardware, but consideration for the size and weight of the chassis is

important for a safe installation.

The rack rails must be spaced widely enough to accommodate the chassis's external dimensions:

59.50 in. (151.1 cm) high, 36.20 in. (91.95 cm) deep, and 19 in. (48.3 cm) wide. The outer edges of the

front-mounting flanges extend the width to 19.2 in. (48.8 cm), The spacing of rails and adjacent racks must

also allow for the clearances around the chassis and rack that are specified in

for Airflow and Hardware Maintenance for the MX2010 Router" on page
