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.) ● 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. 22 Chapter 1 Hardware overview

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.)
●
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.
