The humidity in the server room is another environmenis critical to the proper functioning of the server. The air conditioning sthe room often controls the humidity as well as the temperature.
• Too much humidity in the air can damage the server’s electronic components. In humid conditions, moisture can condense on the circuit boards and other components and cause short circuits or corrosion.
• Too little humidity in the air can subject the server to electrostatic discharge which also can damage the server’s components.
