About Requirements for Perforated Cabinets

A perforated cabinet has perforations in its front and rear doors and side walls. In addition to the requirements
listed in the “General Requirements for Cabinets and Racks” section, perforated cabinets must meet the
following requirements:

• The front and rear doors must have at least a 60-percent open area perforation pattern, with at least 15

square inches (96.8 square cm) of open area per rack unit of door height.

• The roof should be perforated with at least a 20-percent open area.

• The cabinet floor should be open or perforated to enhance cooling.

The Cisco R Series rack conforms to these requirements.

About Requirements for Open Racks

In addition to the requirements listed in the “General Requirements for Cabinets and Racks” section on page
A-1, if you are mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets the
following requirements:

• The minimum vertical rack space per chassis must be two rack units (RU), equal to 3.47 inches (8.8 cm).

• The horizontal distance between the chassis and any adjacent chassis should be 6 inches (15.2 cm), and

the distance between the chassis air vents and any walls should be 2.5 inches (6.4 cm).
