A.1.2 Humidity, Temperature, and Cleanness
This section describes the requirements for the humidity, temperature, and
cleanness of the equipment room. To ensure the stability and life cycle of the USG
and its components, check that the equipment room meets the requirements.
Ensure that there is no explosive, conductive, magnetic, or corrosive dust or debris
in the equipment room. Dust that settle on the device may cause electrostatic
adsorption, resulting in poor contact of the metal socket connectors and metal
contacts. This shortens the life cycle of the device and causes faults.
In addition to dust and debris, toxic gases, such as SO
cleaned out of the equipment room.
