1.1 Scope This European Standard specifies generic cabling that supports a wide range of communications services for use within a data centre. It covers balanced cabling and optical fibre cabling. This European Standard is based upon and references the requirements of EN 50173-1. This European Standard contains additional requirements that are appropriate to data centres in which the distance over which communications services have to be distributed is the maximum defined for backbone cabling implementations within EN 50173-1. The principles of this European Standard may also be applied to installations that do not fall within this range. In addition to the requirements of EN 50173-1, this European Standard specifies: a) a modified structure and configuration for generic cabling within data centres used to support existing and emerging applications; b) implementation options to reflect the quantity of connections required in data centre infrastructures; c) requirements that reflect the range of operating environments within data centres. Safety (electrical safety and protection, fire, optical power etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting these standards and regulations. 1.2 Conformance For a cabling system to conform to this European Standard: a) the structure and configuration shall conform to the requirements of Clause 4; b) connecting hardware in the cabling structure shall conform to the requirements of Clause 8. c) the performance of channels shall conform to the transmission performance and environmental requirements of Clause 5. This shall be achieved by one of the following: - a channel design and implementation ensuring that the prescribed channel performance Class is met; - attachment of appropriate components to a link design meeting the prescribed performance Class of Annex A. Channel performance shall be assured where a channel is created by adding more than one cord to either end of a link meeting the requirements of Annex A; - using the reference implementations of Clause 6 and compatible cabling components conforming to the requirements of Clauses 7, 8 and 9, based upon a statistical approach of performance modelling. d) local regulations concerning safety shall be met. In addition the following requirements of the EN 50174 series of standards shall be met: e) installation specification and quality planning to address: - the test parameters to be measured; - the sampling levels to be applied; - the treatment of channels or links which fail to meet requirements or for which test results lie within the relevant measurement accuracy; f) administration; g) installation. Test methods to verify conformance with the channel and link requirements of Clause 5 and Annex A respectively are specified in EN 50346. Neither this standard nor EN 50174-1 specifies the test and sampling levels to be adopted. Specifications marked "ffs" (for further study) in EN 50173-1 are preliminary and are not required for conformance to this European Standard.
