Maintaining Your Site Environment
An exhaust fan in the power supply cools the power supply and system by drawing air in through various
openings in the system and blowing it out the back. However, the fan also draws dust and other particles
into the system, causing contaminant buildup, which results in an increase in the system’s internal
temperature and interferes with the operation of various system components.
To avoid these conditions, we recommend keeping your work environment clean to reduce the amount
of dust and dirt around the system, thereby reducing the amount of contaminants drawn into the system
by the power supply fan.
This section discusses various environmental factors that can adversely affect system performance and
longevity.
