Setting Up Your Computer
Installing Your Computer in an Enclosure
Installing your computer in an enclosure can restrict the airflow and impact
your computer’s performance, possibly causing it to overheat. Follow the
guidelines below when installing your computer in an enclosure.
CAUTION:
Before installing your computer in an enclosure, read the safety
instructions that shipped with your computer. For additional safety best practices
information, see the Regulatory Compliance Homepage at
www.dell.com/regulatory_compliance.
NOTICE:
The operating temperature specifications indicated in this document
reflects the maximum ambient operating temperature. The room ambient
temperature needs to be a consideration when you install your computer in an
enclosure. For example, if the ambient room temperature is at 25°C (77°F),
depending on your computer’s specifications, you only have 5° to 10°C (9° to 18°F)
temperature margin before you reach your computer’s maximum operating
temperature. For details about your computer’s specifications, see "Specifications"
on page 31.
• Leave a 10.2-cm (4-in) minimum clearance on all sides of the computer
that have air vents to permit the airflow required for proper ventilation.
• If your enclosure has doors, the doors need to be of a type that allows at
least a 30-percent airflow through the enclosure at the front and at the
back.
NOTICE:
Do not install your computer in an enclosure that does not allow airflow.
Restricting the airflow impacts your computer’s performance, possibly causing it to
overheat.
