This appendix describes the cabinet and rack requirements and i ncludes these sections:

• General Requirements for Cabinets and Racks, page B-1

This section provides the Nexus 7000 Series requirements for the following typ es of racks and cabinets,

assuming an external ambient air temperature range of 41 to 104°F (5 to 40°C):

• Standard perforated cabinets

• Solid-walled cabinets with a roof fan tray (bottom to top cooling)

• Standard open racks

• Four-post telco racks

Note If you select an enclosed cabinet, we recommend that you use one of the following thermally validated

types: standard perforated or solid-walled with a fan tray.

To correctly install the Nexus 7000 Series in a hot-aisle cold-aisle environment, you should fit a cabinet

with baffles to prevent exhaust air from recirculating.

Note The verified cabinet vendors for the Nexus 7000 Series are Panduit and Chatsworth.

The rack or cabinet used to hold a Nexus 7000 Series should meet the following requirements:

• Use a standard 19-inch, four-post Electronic Industries Alliance (EIA) cabinet or rack, with

mounting rails that conform to English universal hole spacing per sect ion 1 of the

ANSI/EIA-310-D-1992 standard.

• Have at least 21 rack units (RU) of usable vertical rack space for one Nexus 7000 series device and

42 RU for two Nexus 7000 Series devices (45 RU is recommended).

Each of the following optional requirements are site specific:

• Accommodate up to two Nexus 7000 10-slot chassis and provide cable manag ement for up to 384

ports for each Nexus 7000 series device.

• Provide the features required for the AC power distribution units (PDUs) for the power supplies

installed in each chassis.
