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.
