Configuring Equipment Racks
The following tips help you plan an acceptable equipment rack configuration:
  •
Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because 
each appliance generates heat. An enclosed rack should have louvered sides and a fan to provide 
cooling air.
  •
When mounting a appliance in an open rack, ensure that the rack frame does not block the intake or 
exhaust ports. If the appliance is installed on slides, check the position of the appliance when it is 
seated all the way into the rack.
  •
In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the 
bottom of the rack can be drawn upward and into the intake ports of the equipment above it in the 
rack. Ensure that you provide adequate ventilation for equipment at the bottom of the rack.
  •
Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through 
the appliance. The best placement of the baffles depends on the airflow patterns in the rack. 
Experiment with different arrangements to position the baffles effectively.
