This European Telecommunication Standard (ETS) has been produced by the Equipment Engineering (EE)

Technical Committee of the European Telecommunications Standards Institute (ETSI).

This ETS is part 2 of a 4 part ETS, aimed at setting out on a common basis, the installation engineering

requirements for telecommunication practice, housing equipment forming part of a public

telecommunications network. Part 1 is a general introduction, and explains the terminology used. This part,

Part 2, specifies the engineering requirements for racks and cabinets and Part 3 the engineering

requirements for miscellaneous racks and cabinets. Part 4 covers engineering requirements for subracks in

This ETS applies to all telecommunication equipment forming part of public telecommunications network.

The requirements for racks which this part lays down are based on the work of IEC Sub Committee 48D (see

This part of European Telecommunication Standard (ETS) 300 119 details requirements for racks/cabinets

which are supplied fully equipped. The racks/cabinets shall be used for housing telecommunication

equipment forming part of a public telecommunication network installed either on the public

Part 1 of this ETS (ETS 300 119-1 [3]) defines the meaning of rack or cabinet in the context of this ETS.
