Informacijska tehnologija - Univerzalni sistemi pokabljenja - 5. del: Podatkovna središča - Dopolnilo A2

Ta evropski standard določa univerzalno polaganje kablov, ki podpira širok razpon komunikacijskih storitev za uporabo v podatkovnih centrih. Zajema uravnoteženo polaganje kablov in polaganje optičnih kablov. Ta evropski standard temelji na zahtevah EN 50173-1 in se sklicuje nanje. Ta evropski standard vsebuje dodatne zahteve, ki so primerne za podatkovne centre, kjer je največja razdalja, na kateri je treba distribuirati komunikacijske storitve, opredeljena z izvedbo hrbteničnega polaganja kablov v EN 50173-1. Načela tega evropskega standarda prav tako lahko veljajo za inštalacije, ki niso v tem obsegu.

Insert the following new Annex C.
Annex C
(normative)
Intermediate distribution cabling subsystem
C.1 General

Larger data centres may require an additional subsystem in order to support a reasonable

administration system that will allow for the interconnection of several main distributors. In such case

the main distributor will become the common distributor, which now connects several intermediate

distributors, which act as local main distributors.

This annex defines the additional requirements that are required for such implementations.

C.2 Structure
C.2.1 Functional elements

In addition to the distributors specified in 4.1, Annex C specifies the following functional element and

interface of generic cabling:
– intermediate distributor (ID).
C.2.2 General structure and hierarchy

Generic cabling systems in accordance with this annex contain an additional cabling subsystem: the

intermediate distribution cabling subsystem. Network access cabling subsystems may be connected

directly to the intermediate distributor.

The cabling subsystems are connected together to create a generic cabling system with a structure as

shown in Figure C.1. The composition of the intermediate distribution cabling subsystem is described in

C.2.3. The functional elements of the cabling subsystems are interconnected to form a basic hierarchical

topology as shown in Figure C.2.

Where the functions of distributors are combined (see 4.7.1) the cabling subsystems linking them are

not required.

Connection to application-specific equipment at an ID adopts an interconnect or a cross-connect

approach (see EN 50173-1). Passive connections between cabling subsystems adopt either a cross-

connect approach, by way of either patch cords or jumpers, or an interconnect approach.

C.2.3 Cabling subsystems
C.2.3.1 Main distribution cabling subsystem

The main distribution cabling subsystem extends from an MD to the IDs connected to it. The

subsystem includes
a) the main distribution cables,

b) the mechanical termination of the main distribution cables at the MD together with associated

patch cords and/or jumpers at the MD,
c) the mechanical termination of the main distribution cables at the ID.

Although equipment cords are used to connect the transmission equipment to the cabling subsystem,

they are not considered part of the main distribution cabling subsystem because they are application-

specific.
C.2.3.2 Intermediate distribution cabling subsystem

The intermediate distribution cabling subsystem extends from an ID to the ZDs connected to it. The

subsystem includes
a) the intermediate distribution cables,

b) the mechanical termination of the intermediate distribution cables at the ID together with

associated patch cords and/or jumpers at the ID,
c) the mechanical termination of the intermediate cables at the ZD.

Although equipment cords are used to connect the transmission equipment to the cabling subsystem,

they are not considered part of the intermediate distribution cabling subsystem because they are

application-specific.
