Foreword This European Standard (Telecommunication
14、s series) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document is part 3 of a multi-part deliverable aimed at setting out, on a common basis, the installation engineering requirements for telecommunication practice, for housing equipment forming part of
15、a public telecommunications network. EN 300 119-1 1 is a general introduction and explains the terminology used. EN 300 119-2 2 specifies the engineering requirements for racks and cabinets. The present document specifies the engineering requirements for miscellaneous racks and cabinets. EN 300 119-
16、4 3 covers engineering requirements for subracks in miscellaneous racks and cabinets. EN 300 119-5 4 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
17、 one or more subracks in an rack complying to the requirements of this multi-part standard. The present document applies to all telecommunication equipment forming part of the public telecommunications network. The present document is part 3 of a multi-part deliverable. Full details of the entire se
18、ries can be found in part 1 1.

19、cting National Standard (dow): 31 October 2010 ETSI ETSI EN 300 119-3 V2.2.2 (2010-01) 51 Scope The present document details requirements for miscellaneous racks and cabinets supplied unequipped. The miscellaneous racks/cabinets shall be used for housing telecommunication equipment forming part of a
20、 public telecommunication network installed either on the public telecommunication operators sites or in the premises of operators customers. The miscellaneous racks/cabinets shall be able to accommodate various equipments, e.g. subracks (see EN 300 119-4 3) and shall have provision for doors or cov
21、ers. EN 300 119-1 1 defines the meaning of rack or cabinet in the context of the present document. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

For non-specific references, the latest version of the referenced documen
29、t (including any amendments) applies. Not applicable. 3 Dimensions for miscellaneous racks/cabinets 3.1 Height The height dimension (H) includes covers, feet or castors if these are an integral part of the miscellaneous rack/cabinet structure. For telecommunication centres and customer sites, H shal
30、l be 2 200 mm. The miscellaneous rack/cabinet shall have provision within its height for the attachment of parts for interfacing to any overhead structure. The miscellaneous racks/cabinets shall also be provided with devices which can be height-adjusted to compensate for any unevenness in the floor.
31、 The scope for height adjustment shall be at least 25 mm. The nominal miscellaneous rack/cabinet height shall be measured when the adjustment devices are at their fully retracted positions. 3.2 Width The width dimension (W) includes covers if they are an integral part of the miscellaneous rack/cabin
32、et. W shall be 600 mm. The sides of any miscellaneous rack/cabinet shall not interfere with the assembly of adjacent racks/cabinets (into a straight line-up). The suppliers shall ensure that the miscellaneous rack/cabinet will fit into the space between the grid lines, as illustrated in figure A.1.
33、Manufacturing tolerances shall therefore be so arranged that this objective will always be achieved, even when miscellaneous racks/cabinets are delivered from different suppliers. NOTE: If additional equipment at the end(s) of a suite of miscellaneous racks/cabinets is required the associated coordi
34、nation dimensions should be specified as an integer multiple of the mounting pitch of 25 mm for each side during equipment practice design and should be agreed between supplier and user. 3.3 Depth The depth dimension (D) includes: a) doors or covers of the miscellaneous rack/cabinet structure if pre
35、sent; b) protruding parts e.g. switches, lamps, hinges, locks, electro-static discharge points, etc.; c) connectors, cabling, cooling fins, etc. For the doors or covers a minimum reference value for aisle width shall be 750 mm. Doors or covers which are in the open position shall protrude from the f
36、ront/rear line of miscellaneous racks/cabinets by a maximum of 150 mm. Doors or covers shall be designed so that when open, they do not in any way restrict access to the equipment for essential maintenance and installation operations in that rack or cabinet. D shall be 300 mm or 600 mm. ETSI ETSI EN
37、 300 119-3 V2.2.2 (2010-01) 73.4 Other dimensions For other dimensions of the miscellaneous rack/cabinet, see table 1 and refer to figures A.4 and A.5. 4 Accessibility and line-up of miscellaneous racks/cabinets Miscellaneous racks/cabinets of different depths may be used in any rack/cabinet line-up
38、, but the front line of all racks/cabinets shall be aligned as illustrated in figure A.2 or A.3. Racks/cabinets with a depth of 300 mm shall be accessed only from the front, to allow them to be placed back-to-back or to the wall. The front line of miscellaneous racks/cabinets arranged back to back s
39、hall be aligned to the rear line (see figure A.2 or A.3). 5 Floor loading The maximum permissible miscellaneous rack/cabinet weight depends on the miscellaneous racks/cabinets floor area. To calculate weight per unit area in kN/m2, the actual weight of the miscellaneous rack/cabinet should be divide
40、d by the floor area (W D of the rack/cabinet). The weight per unit area added by the overhead support structure and cabling is also calculated by using the floor area of the supporting miscellaneous rack/cabinet. The arrangement of miscellaneous racks/cabinets has to be planned by the installer to e
41、nsure that the average floor loading for a building is not exceeded. This will be a lower value than the weight per unit area and will depend, for example, on the centre distance of the rack/cabinet rows. 5.1 Weight per unit area of fully equipped miscellaneous rack/cabinet For general applications
42、the weight per unit area fully equipped miscellaneous rack/cabinet, including internal cabling, etc., should not exceed 15 kN/m2. The maximum allowed weight per unit area shall be 20 kN/m2. 5.2 Weight per unit area of cable support structure and cabling The weight per unit area exerted by the releva
43、nt portions of the cable support structure with cabling, should usually not exceed 3 kN/m2. The maximum allowed weight per unit area shall be 8 kN/m2. 5.3 Point loading A point loading exerted by the base of the fully equipped miscellaneous rack/cabinet on the floor shall not exceed 490 N/cm2. NOTE:
44、 Other values for point loading may be adopted by agreement between the supplier and customer. 6 Structural load on a miscellaneous rack/cabinet 6.1 Static load The miscellaneous rack/cabinet shall be able to support a static load of the superstructure with cabling, as described in clause 5. ETSI ET
45、SI EN 300 119-3 V2.2.2 (2010-01) 86.2 Dynamic load During installation, the miscellaneous rack/cabinet shall support an additional load of 800 N for a miscellaneous rack/cabinet of 600 mm 600 mm and 400 N for a miscellaneous rack/cabinet of 600 mm 300 mm. 7 External cable access The miscellaneous ra
46、ck/cabinet design shall enable the cabling for the telecommunication equipment to be routed either over a cable support structure, or under a raised floor, as required i.e. cable access shall be provided in both top and bottom of the miscellaneous rack/cabinet. Direct miscellaneous rack/cabinet to m
47、iscellaneous rack/cabinet cabling is also allowed within rows. External cables shall be located in the area on the left and right hand sides of the miscellaneous rack/cabinet, between the subrack and miscellaneous rack/cabinet structure. The minimum area for cable shall be 6 000 mm2on each side. Thi
48、s figure is based on the use of a 500 mm wide subrack. The area available will increase when a 450 mm wide subrack is installed. 8 Dimensions of packaged miscellaneous rack/cabinet The maximum dimensions of a packaged miscellaneous rack/cabinet shall not exceed: 2 500 mm 1 200 mm 900 mm These maximu
49、m dimensions are stated to allow transportation when using normal lifts, hallways and doors. NOTE: See also figures A.4 and A.5 where dimensions are in mm.
