Cleaning Components
Internal fans cool the computer by drawing in air through air vents in the front of the computer
and blowing it out the rear-side panels. Dust and other debris is drawn in with the air and, if
allowed to build up, will interfere with the operation of various system components and insulate
components, preventing heat from dissipating. To prevent this, an air filter has been installed in
front of the air vents in the front panel to block dust and other debris from entering the
computer.
Dust and debris builds up on the air filter over time. When the air filter becomes very dirty, it is
difficult for cooling air to pass through the air filter and enter the computer. So, the air filter
must be cleaned to prevent the computer from overheating. Remove and clean the air filter on a
regular basis following the steps described in the “Air Filter” section of Chapter 2. Also, regularly
vacuum the exterior of the chassis to remove dust that has accumulated around the air vents.

Environmental Factors
ä ä ä ä
Temperature
The ambient temperature within an enclosure may be greater than room ambient temperature.
Installation in an enclosure should be such that the amount of air flow required for safe
operation is not compromised. Consideration should be given to the maximum rated ambient
temperature. Overheating can cause a variety of problems, including premature aging and failure
of chips or mechanical failure of devices.
If the system has been exposed to abnormally cold temperatures, allow a two-hour warm-up
period to bring it up to normal operating temperature before turning it on. Failure to do so may
cause damage to internal components, particularly the hard disk drive.
