12、 essential to the present document. Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document is part 4 of a multi-part deliverable aimed at setting out, on a common basis, the engineering requireme
13、nts for telecommunication practice, for housing equipment forming part of a public telecommunications network. EN 300 119-1 2 is a general introduction and explains the terminology used. EN 300 119-2 3 specifies the engineering requirements for racks and cabinets and EN 300 119-3 4 specifies the eng
14、ineering requirements for miscellaneous racks and cabinets. EN 300 119-5 5 covers the preferred thermal management solutions for subracks, racks/cabinets and miscellaneous racks/cabinets installed indoors in restricted access locations, for the removal of heat dissipated by one or more subracks in a
15、n rack complying to the requirements of this multi-part standard. The present document specifies the engineering requirements for subracks mounted in miscellaneous racks and cabinets. The present document applies to all telecommunications equipment forming part of the public telecommunications netwo
16、rk. Illustrative figures are contained in annex A. The present document is part 4 of a multi-part deliverable. Full details of the entire series can be found in part 1 2. National transposition dates Date of adoption of this EN: 24 September 2004 Date of latest announcement of this EN (doa): 31 Dece

18、n miscellaneous racks/cabinets, as described in EN 300 119-3 4. The subrack will normally be supplied as a fully assembled structure, unequipped, partially equipped or fully equipped with plug-in units, etc. 2 References The following documents contain provisions which, through reference in this tex

Supply of subracks exceeding 18 kg, if requested, shall be agreed between the supplier and user. 5.2 Equipped subrack On demand, the supplier shall provide administrations, operators or customers
27、 with the total weight of the equipped subrack to enable the fully equipped miscellaneous rack/cabinet weight to be determined for telecommunications centres and customer site floor loading calculations. 6 Electromagnetic compatibility and electrostatic discharge requirements Subracks to be installe
28、d in miscellaneous racks/cabinets must take account of the EEC Council Directive on the approximation of laws of the Member States relating to electromagnetic compatibility (Directive 89/336/EEC 1). In accordance with the terms of this Directive, due regard shall be taken of the appropriate existing
29、 and emerging standards concerning electromagnetic compatibility phenomena. NOTE: See also figures A.1 and A.2 where dimensions are in mm.

This is not a manufacturing dimension with a tolerance. An aperture dimension is a special coordination dimension
33、for a usable space between features. An actual outside dimension corresponding to a coordination dimension can only decrease. An actual inside dimension corresponding to an aperture dimension can only increase. ETSI ETSI EN 300 119-4 V2.1.1 (2004-09) 8 Annex A (informative): Illustrative figures Fig
