Maintaining Your Site Environment
An exhaust fan in the power supply cools the power supply and the AVS 3120 by drawing in air through various openings and blowing it out through the back panel. However, the fan might also draw dust and other particles into the AVS 3120, causing contaminant buildup, which increases the chassis internal temperature and interferes with the operation of various components.
To avoid these conditions, we recommend keeping your work environment clean to reduce the amount of dust and dirt around the AVS 3120 and to reduce the amount of contaminants drawn into it by the power supply fan.
This section discusses various environmental factors that can adversely affect AVS 3120 performance and longevity, and it covers these topics:
•Temperature
•Humidity
•Altitude
•Dust and Particles
•Corrosion
•Electrostatic Discharge
•Electromagnetic and Radio Frequency Interference
•Power Source Interruptions
