Extreme Networks equipment generates a significant amount of heat. It is essential that
you provide a temperature-controlled environment for both performance and safety.
Install the equipment only in a temperature- and humidity-controlled indoor area that is free of
airborne materials that can conduct electricity. Too much humidity can cause a fire. Too little humidity
can produce electrical shock and fire.
