The present document is part 7 of a multi-part deliverable aimed at setting out, on a common basis, the engineering requir

14、ements for telecommunication practice, for housing equipment forming part of a public telecommunications network. ETSI EN 300 119-1 i.1 is a general introduction and explains the terminology used. ETSI EN 300 119-2 i.2 specifies the engineering requirements for racks and cabinets and ETSI EN 300 119

15、-3 i.3 specifies the engineering requirements for miscellaneous racks and cabinets. ETSI EN 300 119-5 i.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 dissipat

16、ed by one or more subracks in an rack complying to the requirements of this multi-part standard. The present document specifies the engineering requirements for subracks mounted in harmonized racks and cabinets with extended features. The present document applies to all telecommunications equipment

17、forming part of the public telecommunications network. The present document, ETSI EN 300 119-7, is defining extension to the existing parts of the standard to harmonize dimensions and to extend rack installation capabilities. These extended features are: mounting bracket depth adjustment only on sub

18、rack level (as normally done in many other standardized equipment practices; see 19 inches) common position of mounting brackets for both 300 mm and 600 mm depth recessed subrack mounting plane compared to ETSI EN 300 119-3 i.3 and ETSI EN 300 119-4 i.4 to allow more room for cable management and be

19、tter cable access from front/rear aisle design subrack mounting plane in a manner so that not only 600 mm deep rack is a earthquake proof design but also the 300 mm rack (600 mm: 7 inches deep upright; 300 mm 3,5 inches deep upright; commonality with EIA rack standard for SNBF) make ETSI mounting pr

20、inciple similar to SNBF (5 inches deep upright) which is used in USA telecommunication offices to gain more commonality for international markets define extra front side cabling space for accommodating optical and electrical I/O cables Illustrative figures are contained in annex A.

For a maximum of installation flexibility, the mounting brackets shall be replaceable by different mounting bracket types or

37、 they shall just be adjustable depthwise. Hence they shall not be an integrated part of subrack side plates but separate parts. For a table of dimensions, see table 1 and refer to figures A.1, A.2, A.3 and A.4. 5 Accessibility Subracks fitting in a harmonized rack/cabinet with extended features or a

38、 miscellaneous rack/cabinet of depth 300 mm shall require access only from the front, so that they can be placed in harmonized rack/cabinet with extended features or miscellaneous racks/cabinets which are back to back or against a wall. 6 Weight 6.1 Unequipped subrack Unequipped subracks shall have

39、a maximum weight of 18 kg for safe handling. Supply of subracks exceeding 18 kg, if requested, shall be agreed between the supplier and user. 6.2 Equipped subrack On demand, the supplier shall provide administrations, operators or customers with the total weight of the equipped subrack to enable the

40、 fully equipped miscellaneous rack/cabinet weight to be determined for telecommunications centres and customer site floor loading calculations.
