This ETSI Standard (ES) has been produced by ETSI Technical Committee Environmental Engineering (EE).

The present document is part 12 of a multi-part deliverable covering monitoring and control interface for infrastructure

equipment (power, cooling and building environment systems used in telecommunication networks), as identified

Part 5: "AC diesel back-up generator system control and monitoring information model";

Part 11: "Battery system with integrated control and monitoring information model";

Part 12: "ICT equipment power, energy and environmental parameters monitoring information model".

The goal of the present document is to define the measurement of electrical power and energy consumption of ICT

equipment as well as environmental parameters (temperature, hygrometry) in order to improve energy monitoring and

to correlate the power consumption to equipment operation activity (telecom traffic, computation, etc.). It is also to

define the transfer protocol of this measurement data from site to network operation centre. Knowing power

consumption gives the possibilities to reduce energy consumption of equipment and/or network. Granularity,

measurement period and accuracies are defined to meet these targets. They may depend on equipment types and

location in the different segments of a network (customer termination, access, core, data-center, etc.). In addition, these

measurements can be used to improve engineering and operation including more accurate dimensioning of power

"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of

"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

The present document defines measurement and monitoring of power, energy and environmental parameters for ICT

It defines the power, energy and environmental parameters monitoring interface of ICT equipment based on generic

ETSI ES 202 336-1 [1] interface so that correlations can be made with ICT equipment parameters (traffic, flowrate,

number of connected lines, radio setting, QoS KPI, etc.) in the network management system.

Correlations of monitored data (power, energy consumption and environmental values) with the ICT equipment

• Internal power consumption measurement on the ICT equipment powered in DC and AC.

• Power consumption measurement external to the ICT equipment (if not implemented internally, e.g. legacy

• Environmental parameters of the ICT equipment (e.g. temperature at air inlet of equipment).

• The minimum set of exchanged information required at the interface, including parameters such as

measurement type (e.g. RMS), accuracy, range, etc. and settings such as data acquisition and transmission

period, etc. This includes the data preparation, recording and transmission functions.

• Text tables in annexes A and B with data exchange described in "natural language".

• The XML files with tags and variables corresponding to the data in the tables of annexes A and B in

complement to general rules defined in ETSI ES 202 336-1 [1] and ETSI ES 202 336-2 [3].
