Requirements Specific to Solid-Walled Cabinets
In addition to the requirements listed in the
General Requirements for Cabinets and Racks
section, solid-walled
cabinets must meet the following requirements:
• The rack must have a roof-mounted fan tray and an air-cooling scheme in which the fan tray pulls air in
at the bottom of the cabinet and sends it out from the top, with a minimum airflow of 849.5 m3/h exiting
the cabinet roof through the fan tray, should be available.
• The front and rear doors, and side panels, must be installed and nonperforated so that air flows predicatably
from bottom to top.
• The overall cabinet depth should be 36 to 42 in. (91.4 to 106.7 cm) to allow the doors to close and to
facilitate adequate airflow.
• The open area of the floor air intake must be a minimum of 150 sq. in. (968 sq. cm).
• The lowest piece of equipment should be installed at a minimum of 1.75 in. (4.4 cm) above the floor
openings to prevent blocking the floor intake.
