Cabinet and Rack Installation
• 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 exhausts it out the top, with a minimum of 849.5 m
through the fan tray.
• Nonperforated (solid and sealed) front and back doors and side panels so that air travels predictably
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
adequate airflow.
• A minimum of 150 sq. in. (968 sq. cm) of open area at the floor air intake of the cabinet.
• The lowest piece of equipment should be installed a minimum of 1.75 in. (4.4 cm) above the floor
openings to prevent blocking the floor intake.
