Rack Requirements for ACX7100-48L Routers

 

ACX7100-48L routers are designed to be installed on four-post racks. Table 1 provides the rack requirements and specifications for ACX7100-48L routers.

Rack Requirement

Guidelines

Rack type

Use a four-post rack that provides bracket holes or hole patterns that are spaced at 1-U increments (1.75 in. or 4.45 cm), and ensure that the rack meets the size and strength requirements to support the weight.

A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

Mounting bracket hole spacing

Ensure that the holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm) so that the router can be mounted in any rack that provides holes spaced at that distance.

Rack size and strength

  • Ensure that the rack complies with the standards for a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

  • Use an 800-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 (http://www.etsi.org).

    The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the device's mounting brackets, which measure 19 in. (48.26 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.

  • Ensure that the rack rails are spaced widely enough to accommodate the router chassis’ external dimensions. The outer edges of the front-mounting brackets extend the width to 19 in. (48.26 cm).

  • Ensure that for four-post installations, the front and rear rack rails are spaced between 23.6 in. (60 cm) and 36 in. (91.4 cm) front-to-back.

  • Ensure that the rack is strong enough to support the weight of the router. The fully configured ACX7100-48L router weighs about 26.94 lb (12.22 kg).

  • Ensure that the spacing of rails and adjacent racks allows for proper clearance around the router and rack.

Rack connection to building structure

  • Secure the rack to the building structure.

  • If earthquakes are a possibility in your geographical area, secure the rack to the floor.

  • Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.
