Foreword This European Standard (Telecommunications series
14、) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document is part 2 of a multi-part deliverable, aimed at setting out on a common basis, the installation engineering requirements for telecommunication practice, housing equipment forming part of a public tel
15、ecommunications network. EN 300 119-1 i.1 is a general introduction, and explains the terminology used. The present document specifies the engineering requirements for racks and cabinets and EN 300 119-3 i.2 the engineering requirements for miscellaneous racks and cabinets. EN 300 119-4 i.3 covers e
16、ngineering requirements for subracks in miscellaneous racks and cabinets. EN 300 119-5 i.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 one or mo
17、re subracks in an rack complying to the requirements of the present document. The present document applies to all telecommunication equipment forming part of public telecommunications network. Illustrative figures are contained in annex A. The present document is part 2 of a multi-part deliverable.

ETSI ETSI EN 300 119-2 V2.2.2 (2009-12) 63 Coordination dimensions for racks/cabinets 3.1 Height The height dimension (H) includes covers, feet or castors if these are an integral part of the rack/c
29、abinet structure. For telecommunication centres, H shall be 2 200 mm. For customer sites, H may be at any preferred height, as defined in EN 60917-2 1, up to 2 200 mm. Provision shall be made for the possible fitment of height adaptors (for interfacing with overhead structures) as illustrated in fig
30、ure A.1. The racks/cabinets shall also be provided with devices which can be height-adjusted to compensate for any unevenness in the floor. The scope for height adjustment shall be at least 25 mm. The nominal rack/cabinet height shall be measured when the adjustment devices are at their fully retrac
31、ted positions. 3.2 Width The width dimension (W) includes covers if they are an integral part of the rack/cabinet. W shall be one of four permitted dimensions: 150 mm, 300 mm, 600 mm or 900 mm. The sides of any rack/cabinet shall not interfere with the assembly of adjacent racks/cabinets (into a str
32、aight line-up). The suppliers must ensure that the rack/cabinet will fit into the space between the grid lines, as illustrated in figure A.4. Manufacturing tolerances shall therefore be so arranged that this objective will always be achieved, even when racks/cabinets are delivered from different sup
33、pliers. NOTE: If additional equipment at the end(s) of a suite of racks/cabinets is required, the associated coordination dimensions can 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
34、.3 Depth The depth dimension (D) includes: a) doors or covers of the rack/cabinet if present; b) all protruding parts e.g. switches, lamps, hinges, locks, electrostatic discharge points, etc.; c) connectors, cabling, cooling fins, etc. For the doors or covers, a minimum reference value for aisle wid
35、th shall be 750 mm. Doors or covers which are in the open position shall protrude from the front/rear line of 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
36、 operations. D shall be 300 mm or 600 mm. 4 Accessibility and line-up of racks/cabinets Racks/cabinets of different depths may be used in the same rack/cabinet line-up, but the fronts of all the racks/cabinets shall then be aligned, as illustrated in figure A.2 or A.3. Racks/cabinets with a depth of
37、 300 mm shall be accessed only from the front, to allow them to be placed back-to-back or to the wall. The front of racks/cabinets arranged backwards shall be aligned to the rear line (see figure A.2 or A.3). ETSI ETSI EN 300 119-2 V2.2.2 (2009-12) 75 External cable access The rack/cabinet design sh
38、all 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 must be provided in both top and bottom of the rack/cabinet. Direct rack/cabinet-to-rack/cabinet cabling is also allowed within rows.
39、 6 Floor loading The maximum permissible rack/cabinet weight depends on the racks/cabinets floor area. To calculate weight per unit area in kN/m2, the actual weight of the rack/cabinet should be divided by the floor area (W D of the rack/cabinet). The weight per unit area added by the overhead suppo
40、rt structure and cabling is also calculated by using the floor area of the supporting rack/cabinet. The arrangement of racks/cabinets has to be planned by the installer to ensure that the average floor loading for a building is not exceeded. This will be a lower value than the weight per unit area a
41、nd will depend, for example, on the centre distance of the rack/cabinet rows. 6.1 Weight per unit area of fully equipped rack/cabinet For general applications, the weight per unit area of a fully equipped rack/cabinet, including internal cabling, etc. should not exceed 15 kN/m2. The maximum allowed
42、weight per unit area shall be 20 kN/m2. 6.2 Weight per unit area of cable support structure and cabling The weight per unit area exerted by the relevant 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.
43、 6.3 Point loading A point loading exerted by the base of the rack/cabinet on the floor shall not exceed 490 N/cm2. NOTE: Other values for point loading may be adopted by agreement between the supplier and customer. 7 Structural load on a rack/cabinet 7.1 Static load The rack/cabinet shall be able t
44、o support a static load of the superstructure with cabling, as described in clause 6. 7.2 Dynamic load During installation, the rack/cabinet shall be able to support an additional load of 800 N for a rack/cabinet of 600 mm 600 mm or greater; pro rata values shall apply to the other smaller racks/cab
45、inets. 8 Dimensions of packaged rack/cabinet The maximum dimensions of a packaged rack/cabinet shall not exceed 2 500 mm 1 200 mm 900 mm. These maximum dimensions are stated to allow transportation when using normal lifts, hallways and doors. ETSI ETSI EN 300 119-2 V2.2.2 (2009-12) 89 Electromagneti
