This document is a compilation of recommended Practices for improving the energy management (i.e. reduction of energy consumption and/or increases in energy efficiency) of data centres. It is historically aligned with the EU Code of Conduct for Data Centre Energy Efficiency (CoC) scheme operated by the Directorate-General Joint Research Centre (DG JRC) of the European Commission (EC).
It is recognized that the Practices included might not be universally applicable to all scales and business mod...view more

This document specifies provision of connectionless user data confidentiality, frame data integrity, and data origin authenticity by media access independent protocols and entities that operate transparently to MAC Clients. NOTE—The MAC Clients are as specified in IEEE Std 802®, IEEE Std 802.1Q?, and IEEE Std 802.1X.2 To this end, it a) Specifies the requirements to be satisfied by equipment claiming conformance to this standard. b) Specifies the requirements for MACsec in terms of provision of ...view more

This document specifies Bridges that interconnect individual LANs, each supporting the IEEE 802 MAC Service using a different or identical media access control method, to provide Bridged Networks and VLANs.

This EN specifies the so-called Energy Reuse Factor (ERF) as a KPI to quantify the reuse of the energy consumed in the data centre. The ERF does reflect the efficiency of the reuse process, however, the reuse process is not part of the data centre.

This European Standard specifies requirements for the following aspects of information technology cabling:
a)   installation specification, quality assurance documentation and procedures;
b)   documentation and administration;
c)   operation and maintenance.
This European Standard is applicable to all types of information technology cabling including generic cabling systems designed in accordance with the EN 50173 series.
