This standard also applies to the following technical equipment: - designed to be used as communication terminal equipment and communication network infrastructure equipment, regardless of the way of power supply: - designed and intended to be directly connected to or used as infrastructure equipment in cable distribution systems, The way of power supply is not considered; - the design uses the AC mains power supply as the information transmission medium (see Note 4 of Chapter 6 and Note 4 of 7.1). This section also applies to components and assemblies intended to be installed inside information technology equipment. These components or assemblies are not required to comply with all requirements of this standard if the complete information technology equipment in which they are installed complies with the requirements of this standard. This section specifies a series of requirements to reduce the risk of fire, electric shock or injury to operators and laymen who may come into contact with the equipment. When specified, this also includes maintenance personnel. This section aims to reduce: the installed equipment in accordance with the method specified by the manufacturer during installation, operation and maintenance hazards.
