Ensuring proper ventilation
Proper ventilation for the system is important for workstation operation. Follow these guidelines:
Operate the workstation on a sturdy, level surface.
Provide at least 15.24 cm (6 inches) of clearance at the front and back of the workstation.
(Workstation models vary.)
Figure 1-26 Proper workstation ventilation
Ensure that the ambient air temperature falls within the environmental specifications listed in this
document.
NOTE: The ambient upper limit of 35°C (95°F) is only good up to 1524 m (5000 ft) elevation.
There is a 1°C (33.8°F) per 304.8 m (1000 ft) derating above 1524 m (5000 ft). So, at 3,048 m
(10,000 ft), the upper ambient air temperature limit is 30°C (86°F).
For cabinet installation, ensure adequate cabinet ventilation and ensure that the ambient
temperature within the cabinet does not exceed specified limits.
Never restrict the incoming or outgoing airflow of the workstation by blocking any vents or air
intakes, as shown in the following figure.
