6 Final draft ETSI ES 202 336-12 V1.2.1 (2018-12)
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
systems, network evolution modelling and prevision, audit on field, etc.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document defines measurement and monitoring of power, energy and environmental parameters for ICT
equipment in telecommunications or datacenter or customer premises.
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
parameters and settings are not in the scope of the present document.
The monitoring interface covers:
• 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
equipment).
• Energy metering based on power consumption measurement.
• Environmental parameters of the ICT equipment (e.g. temperature at air inlet of equipment).
The present document defines:
• 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.
• The testing method of some parameters and 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].

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
systems, network evolution modelling and prevision, audit on field, etc.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document defines measurement and monitoring of power, energy and environmental parameters for ICT
equipment in telecommunications or datacenter or customer premises.
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
parameters and settings are not in the scope of the present document.
The monitoring interface covers:
• 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
equipment).
• Energy metering based on power consumption measurement.
• Environmental parameters of the ICT equipment (e.g. temperature at air inlet of equipment).
The present document defines:
• 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.
• The testing method of some parameters and 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].

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
NOTE: Terms referring to energy interface, equipment and distribution are described in power distribution
standards ETSI ETS 300 132-1 [2], ETSI EN 300 132-3-1 [i.15], ETSI EN 300 132-2 [6] for ac and dc
interface A and A3 and ETSI EN 302 099 [i.14] for access network equipment powering.
AC distribution power system: device or system that distribute AC voltage or convert DC voltage to AC voltage and
provides electrical power without interruption in the event that commercial power drops to an unacceptable voltage
level
alarm: any information signalling abnormal state, i.e. different to specified normal state of hardware, software,
environment condition (temperature, humidity, etc.)
NOTE: The alarm signal should be understood by itself by an operator and should always have at least one
severity qualification or codification (colour, level, etc.). alarm message structure are defined in ETSI
ES 202 336-1 [1].
EXAMPLE: Rectifier failure, battery low voltage, etc.
board: electronic part of an equipment (e.g. a blade server)
cabinet: closed enclosure including several shelves or racks
Control Unit (CU): integrated unit in an equipment to monitor and control this equipment through sensors and
actuators
Data Gathering Unit (DGU): functional unit used for several functions:
• collect serial, digital, and analog data from several equipment;
• option to send (output) serial or digital commands;
• forward/receive information to/from the Local/Remote Management Application via agreed protocols;
• mediation between interfaces and protocols.
NOTE: This function may be integrated as part of specific equipment.
DC back-up system: device or system that provides electrical power without interruption in the event that commercial
power drops to an unacceptable voltage level
DC distribution power system: device or system to distribute DC voltage
ethernet: LAN protocol
NOTE: Equivalent to IEEE 802.1 to 802.11 [i.1].
event: any information signalling a change of state which is not an alarm: e.g. battery test, change of state of battery
