Environmental Engineering (EE) - Monitoring and control interface for infrastructure equipment (power, cooling and building environment systems used in telecommunication networks) - Part 12: ICT equipment power, energy and environmental parameters monitoring information model

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].

Okoljski inženiring (EE) - Nadzorovalni in krmilni vmesnik za infrastrukturno opremo (elektroenergetski, hladilni in stavbni okoljski sistemi v telekomunikacijskih omrežjih) - 12. del: Oprema za napajanje IKT, energija in okoljski parametri za nadzorovanje informacijskega modela

Ta dokument določa meritev in nadzor napajanja, energije in okoljskih parametrov za opremo IKT v telekomunikacijskih ali podatkovnih središčih oz. prostorih strank.
Opredeljuje nadzorovalni vmesnik za napajanje, energijo in okoljske parametre opreme IKT na podlagi splošnega vmesnika ETSI ES 202 336-1 [1], da je mogoče vzpostaviti korelacije s parametri opreme IKT (promet, pretok, število povezanih linij, radijska nastavitev, kakovost storitve, ključni indikator zmogljivosti (KPI) itd.) v sistemu za upravljanje omrežja.
Korelacije nadzorovanih podatkov (napajanje, poraba energije in okoljske vrednosti) s parametri in nastavitvami opreme IKT niso zajete v področje uporabe tega dokumenta.
Nadzorovalni vmesnik zajema:
• meritev porabe notranje energije v opremi IKT z enosmernim in izmeničnim napajanjem;
• meritev porabe zunanje energije opreme IKT (če ni na voljo notranje napajanje, npr. pri starejši opremi);
• merjenje energije na podlagi izmerjene porabe energije;
• okoljske parametre opreme IKT (npr. temperatura pri vstopni odprtini za zrak na opremi). Ta dokument določa:
• najmanjši nabor izmenjanih informacij, ki se zahtevajo na vmesniku, vključno s parametri, kot so vrsta meritve (npr. RMS), točnost, doseg itd., ter nastavitvami, kot sta obdobji zajemanja in prenosa podatkov itd. To vključuje funkcije za pripravo, zapisovanje in prenos podatkov;
• metodo preskušanja nekaterih parametrov in funkcij;
• besedilne preglednice v dodatkih A in B z izmenjavo podatkov, opisano v »naravnem jeziku«;
• datoteke XML z oznakami in spremenljivkami, ki ustrezajo podatkom v preglednicah dodatkov A in B ter dopolnjujejo splošna pravila, opredeljena v dokumentih ETSI ES 202 336-1 [1] in ETSI ES 202 336-2 [3].

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.

The basic principles of power, energy and environment parameters measurements of ICT equipment (temperature,
hygrometry) and their transfer to the network management systems (NMS) are shown in figure 1.
NOTE 1: The definition of specific NMS for mobile or fixed networks is out of scope of the present document. The
same comment applies to OSS.
ETSI
13 Final draft ETSI ES 202 336-12 V1.2.1 (2018-12)
The following measuring device are used:
• wattmeter or energy meter (W, Wh); and/or
• Voltage (V); and/or
• current meter (A).
Voltage or current shall be recorded for monitoring when used to assess the power and energy consumption.
Temperature shall also be measured and recorded.
NOTE 2: The energy consumption can be calculated from power measurement over a period of time.
NOTE 3: Humidity should be measured at the level of room or air conditioning, not at equipment level.
In the preferred implementation, power and energy measurements shall be taken down-stream of power supply interface
A or A3 as defined in ETSI ETS 300 132-1 [2], ETSI EN 300 132-2 [6] and ETSI EN 300 132-3-1 [i.15] and inside the
ICT equipment (type 1 measurement).
Otherwise e.g. on legacy equipment, power and energy measurements can be taken upstream of interface A outside the
ICT equipment (type 2 measurement).
The electrical measurement sensors shall be located the closest as possible of the power electrical interface (A or A3)
and the thermal environment sensors shall be placed in the air flow of the air inlet of the equipment.
PEE measurement values can be transmitted directly from XCU or DGU to XRMS or indirectly by the NE through the
TMN protocol over the NMS to the XRMS. The direct and indirect transmission shall comply with ETSI
ES 202 336-1 [1] and the present document's protocol.
NOTE 4: The Network Management System (NMS) is the functional entity from which the network operator
monitors and controls the system at centralized level and manage operational and maintenance activities,
it is using a TMN protocol not defined in the present document. The operation and Maintenance functions
are based on the principles of the Telecommunication Management Network (TMN) of Recommendation
ITU-T M.3010 [i.12] introduced by Recommendation ITU-T M.3000 series [i.11].
NOTE 5: The measurements done using the present document can be used as inputs for enabling:
 the assessment of Power Consumption in Broadband Telecommunication Networks Equipment
[i.3], Transport Telecommunication Networks Equipment [i.6] and Customer Premises Equipment
(CPE) [i.8];
 the assessment of Energy efficiency of wireless access network equipement [i.4], Core network
equipment [i.5], router and switch equipment [i.7] and Mobile Network [i.10];
 the power management capabilities of the future energy telecommunication fixed network nodes
with Green Abstraction Layer (GAL) [i.9].

NOTE 1: In figure 1, some ICT sites may not have all of the parts (building, power, cooling) and therefore monitoring
interface would not be required.
NOTE 2: An ICT equipment of a vendor X is in general connected to the NMS of the vendor X, but the power/air
conditioning /building infrastructure XRMS can be from a vendor Y.

Figure 1: Principle of the monitoring of ICT equipment power, energy and environment parameters
4.2 Complementarity to existing site power and air-conditioning
measurements
The power/energy and environmental (PEE) parameters measurement on ICT equipment as standardized in the present
document are complementary to the measurements defined at the site and room level on the power and air conditioning
systems introduced in standard ETSI ES 202 336-1 [1].
In particular the standard ETSI ES 202 336-2 [3], ETSI ES 202 336-3 [4], ETSI ES 202 336-4 [7], ETSI
ES 202 336-6 [8] and ETSI ES 202 336-10 [5] shall be used for definition of PEE measurements monitored by non ICT
equipment in telecommunications or datacenter or customer premises (e.g. power, cooling and distributions systems):
• AC and DC current, voltage and or power sensors;
• AC and DC energy meters;
• Voltage, current, AC frequency measurement sensors;
• True Power factor measurement device;
NOTE 1: The true Power Factor includes the AC Displacement Factor (i.e. the cosinus of the phase angle between
AC current and voltage of 50 Hz fundamental signals) and the current Distorsion Factor. The current
distorsion is the highest factor for ICT load powered by SMPS as phase angle is close to 0. The distortion
factor is a measurement of the performance of the PFC (Power Factor Correction) function.
ETSI
15 Final draft ETSI ES 202 336-12 V1.2.1 (2018-12)
• Sensors bus e.g. for power metering;
• Additional measurements.
NOTE 2: For very critical site, there could be additional power quality monitoring measurements (e.g. harmonic
currents amplitude, power factor, distorsion, dips, etc.) as defined in ETSI ES 202 336-4 [7].
NOTE 3: All the PEE measurements transmitted through ETSI ES 202 336 (all series) [i.16] can be used to get
measurements complementary to those defined in the present document e.g. DC current or power
measurement compliant to ETSI ES 202 336-2 [3] at the output of a DC system supplying one or several
ICT equipment.
4.3 Different site cases
4.3.1 Simple site case
Two types (see figure 2) of PEE monitoring can exist in a simple ICT site, and the compatibility is ensured between
these types with the remote monitoring:
• Type 1: built-in measurements inside ICT equipment down-stream from interface A (or A3).
• Type 2: external measurement at input junction box measurements up-stream from interface A (or A3).
Internal power consumption and environment sensors and external measurement connected to an energy
metering/environment XCU shall be used as defined in clause 4.4. Humidity measurements are optional.
Data export from NMS to the power/cooling remote management server shall use the ETSI ES 202 336-1 [1] and the
present document. The NMS can also be used for dialog with other type of server as explained in clause 4.5.
ETSI
16 Final draft ETSI ES 202 336-12 V1.2.1 (2018-12)

Figure 2: Example of possible implementation in a simple Telecom site
(e.g. a radio mobile site with ICT/Telecom connected to an OSS/NMS)
4.3.2 Complex site case
Figure 3 gives example of 3 cases of monitoring of PEE that can exists in a complex ICT site, and how compatibility is
ensured between these cases with the remote monitoring:
• Type 1: built-in measurements inside ICT equipment down-stream from interface A (or A3).
• Type 2: external measurement at input junction box measurements up-stream from interface A (or A3).
• Type 3: power frame measurement at output of power supply system.
On complex big sites with many equipment from different manufacturers and of different types, users require power
and energy measurement of each ICT equipment and the global monitoring provided in power and air-conditioning is
not sufficiently accurate.
For measurement on the power system and power distribution frame, the issue is to manage on the long run the cabling
tracing and identification to be sure that the measurement always corresponds to the same considered ICT equipment. It
often happen that a power output cable is common to several equipment, powered in room through a secondary
distribution cabinet with smaller cables. With redundancy and double distribution from separate sources it is even more
complicated. In addition the distribution is changing with the evolutive life of the site.
For air condition, this can happen that the sensors are not located close enough to the ICT equipment so that the sensor
does not reflect the condition really seen by the ICT equipment.
So it seems much more reliable and stable to define the closest measurement as possible of the power input and of air
inlet of the ICT equipment.
ETSI
17 Final draft ETSI ES 202 336-12 V1.2.1 (2018-12)
It is preferred to measure power inside the ICT equipment on the power input lines. If not possible it can be done
outside but always downstream interface A or A3 as defined in ETSI ETS 300 132-1 [2], ETSI EN 300 132-2 [6] and
ETSI EN 300 132-3-1 [i.15] of the considered ICT considered element under measurement.
When there are several power interface A or A3 inputs on the same ICT equipment, the sum of all power and energy
measurements shall be provided in the monitored data in addition to individual values.
The temperature and humidity in which the ICT equipment is operating, shall be taken by an external sensor located at
the air inlet of ICT equipment as defined in ETSI EN 300 019-2 series [9].
As in clause 4.3.1 for simple site, the data transmitted to the NMS shall be available on export line to another server as
specified in clause 4.5.

measurement acquisition in a site considering 3 cases of implementations
(power frame measurement, input junction box measurements, built-in measurements)
4.4 Measurement and monitoring description
4.4.0 General description
This description of measurement is split in the 3 following clauses (clauses 4.4.1 to 4.4.3):
• downstream interface A or A3 built-in measurement for new equipment (type 1);
• upstream interface A or A3 measurement for legacy equipment (type 2);
• common requirements.
ETSI
18 Final draft ETSI ES 202 336-12 V1.2.1 (2018-12)
4.4.1 Internal measurements type 1 (Built-in in ICT equipment)
Power consumption measurement are done inside the ICT equipment.
The priority of measurement is on power inputs downstream of interface A of equipment, to be intended for the purpose
of the present document as interface A at shelf level (both for deployment in a rack or in a cabinet enclosure).
Optionally it can be provided measurement at board level.
In table 1, the power/energy/temperature measurement defined for each network element shall be applied.

4.4.2 External measurements type 2 (external sensors) for ICT equipment
The measurement type 2 of the ICT equipment (same list as in table 1) is done externally upstream from interface A by
the following means:
• Current, Voltage sensors or Power or Energy Meters installed in electrical junction box or final power
distribution frames or by sensors for current.
• Multi sensor Acquisition unit.
• A PEE DGU or XCU.
NOTE: Sensors or meters can be interconnected to this XCU or DGU, by a bus.
The monitoring interface at the level of the XCU or DGU is ETSI ES 202 336-1 [1] with data information model of the
present document.
Other environmental measurements (temperature, humidity) shall be associated in order to perform correlation with the
power/energy measurements on the considered equipment. The temperature or humidity sensors have to be very close to
the air inlet of this equipment, which means several measurements on a multicabinet system.

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].

4 ICT power, energy and environmental parameters
monitoring system
4.1 General description
The basic principles of power, energy and environment parameters measurements of ICT equipment (temperature,
hygrometry) and their transfer to the network management systems (NMS) are shown in figure 1.
NOTE 1: The definition of specific NMS for mobile or fixed networks is out of scope of the present document. The
same comment applies to OSS.
ETSI
13 ETSI ES 202 336-12 V1.2.1 (2019-02)
The following measuring device are used:
• wattmeter or energy meter (W, Wh); and/or
• Voltage (V); and/or
• current meter (A).
Voltage or current shall be recorded for monitoring when used to assess the power and energy consumption.
Temperature shall also be measured and recorded.
NOTE 2: The energy consumption can be calculated from power measurement over a period of time.
NOTE 3: Humidity should be measured at the level of room or air conditioning, not at equipment level.
In the preferred implementation, power and energy measurements shall be taken down-stream of power supply interface
A or A3 as defined in ETSI ETS 300 132-1 [2], ETSI EN 300 132-2 [6] and ETSI EN 300 132-3-1 [i.15] and inside the
ICT equipment (type 1 measurement).
Otherwise e.g. on legacy equipment, power and energy measurements can be taken upstream of interface A outside the
ICT equipment (type 2 measurement).
The electrical measurement sensors shall be located the closest as possible of the power electrical interface (A or A3)
and the thermal environment sensors shall be placed in the air flow of the air inlet of the equipment.
PEE measurement values can be transmitted directly from XCU or DGU to XRMS or indirectly by the NE through the
TMN protocol over the NMS to the XRMS. The direct and indirect transmission shall comply with ETSI
ES 202 336-1 [1] and the present document's protocol.
NOTE 4: The Network Management System (NMS) is the functional entity from which the network operator
monitors and controls the system at centralized level and manage operational and maintenance activities,
it is using a TMN protocol not defined in the present document. The operation and Maintenance functions
are based on the principles of the Telecommunication Management Network (TMN) of Recommendation
ITU-T M.3010 [i.12] introduced by Recommendation ITU-T M.3000 series [i.11].
NOTE 5: The measurements done using the present document can be used as inputs for enabling:
 the assessment of Power Consumption in Broadband Telecommunication Networks Equipment
[i.3], Transport Telecommunication Networks Equipment [i.6] and Customer Premises Equipment
(CPE) [i.8];
 the assessment of Energy efficiency of wireless access network equipement [i.4], Core network
equipment [i.5], router and switch equipment [i.7] and Mobile Network [i.10];
 the power management capabilities of the future energy telecommunication fixed network nodes
with Green Abstraction Layer (GAL) [i.9].
ETSI
14 ETSI ES 202 336-12 V1.2.1 (2019-02)

NOTE 1: In figure 1, some ICT sites may not have all of the parts (building, power, cooling) and therefore monitoring
interface would not be required.
NOTE 2: An ICT equipment of a vendor X is in general connected to the NMS of the vendor X, but the power/air
conditioning /building infrastructure XRMS can be from a vendor Y.

Figure 1: Principle of the monitoring of ICT equipment power, energy and environment parameters
4.2 Complementarity to existing site power and air-conditioning
measurements
The power/energy and environmental (PEE) parameters measurement on ICT equipment as standardized in the present
document are complementary to the measurements defined at the site and room level on the power and air conditioning
systems introduced in standard ETSI ES 202 336-1 [1].
In particular the standard ETSI ES 202 336-2 [3], ETSI ES 202 336-3 [4], ETSI ES 202 336-4 [7], ETSI
ES 202 336-6 [8] and ETSI ES 202 336-10 [5] shall be used for definition of PEE measurements monitored by non ICT
equipment in telecommunications or datacenter or customer premises (e.g. power, cooling and distributions systems):
• AC and DC current, voltage and or power sensors;
• AC and DC energy meters;
• Voltage, current, AC frequency measurement sensors;
• True Power factor measurement device;
NOTE 1: The true Power Factor includes the AC Displacement Factor (i.e. the cosinus of the phase angle between
AC current and voltage of 50 Hz fundamental signals) and the current Distorsion Factor. The current
distorsion is the highest factor for ICT load powered by SMPS as phase angle is close to 0. The distortion
factor is a measurement of the performance of the PFC (Power Factor Correction) function.
ETSI
15 ETSI ES 202 336-12 V1.2.1 (2019-02)
• Sensors bus e.g. for power metering;
• Additional measurements.
NOTE 2: For very critical site, there could be additional power quality monitoring measurements (e.g. harmonic
currents amplitude, power factor, distorsion, dips, etc.) as defined in ETSI ES 202 336-4 [7].
NOTE 3: All the PEE measurements transmitted through ETSI ES 202 336 (all series) [i.16] can be used to get
measurements complementary to those defined in the present document e.g. DC current or power
measurement compliant to ETSI ES 202 336-2 [3] at the output of a DC system supplying one or several
ICT equipment.
4.3 Different site cases
4.3.1 Simple site case
Two types (see figure 2) of PEE monitoring can exist in a simple ICT site, and the compatibility is ensured between
these types with the remote monitoring:
• Type 1: built-in measurements inside ICT equipment down-stream from interface A (or A3).
• Type 2: external measurement at input junction box measurements up-stream from interface A (or A3).
Internal power consumption and environment sensors and external measurement connected to an energy
metering/environment XCU shall be used as defined in clause 4.4. Humidity measurements are optional.
Data export from NMS to the power/cooling remote management server shall use the ETSI ES 202 336-1 [1] and the
present document. The NMS can also be used for dialog with other type of server as explained in clause 4.5.
ETSI
16 ETSI ES 202 336-12 V1.2.1 (2019-02)

Figure 2: Example of possible implementation in a simple Telecom site
(e.g. a radio mobile site with ICT/Telecom connected to an OSS/NMS)
4.3.2 Complex site case
Figure 3 gives example of 3 cases of monitoring of PEE that can exists in a complex ICT site, and how compatibility is
ensured between these cases with the remote monitoring:
• Type 1: built-in measurements inside ICT equipment down-stream from interface A (or A3).
• Type 2: external measurement at input junction box measurements up-stream from interface A (or A3).
• Type 3: power frame measurement at output of power supply system.
On complex big sites with many equipment from different manufacturers and of different types, users require power
and energy measurement of each ICT equipment and the global monitoring provided in power and air-conditioning is
not sufficiently accurate.
For measurement on the power system and power distribution frame, the issue is to manage on the long run the cabling
tracing and identification to be sure that the measurement always corresponds to the same considered ICT equipment. It
often happen that a power output cable is common to several equipment, powered in room through a secondary
distribution cabinet with smaller cables. With redundancy and double distribution from separate sources it is even more
complicated. In addition the distribution is changing with the evolutive life of the site.
For air condition, this can happen that the sensors are not located close enough to the ICT equipment so that the sensor
does not reflect the condition really seen by the ICT equipment.
So it seems much more reliable and stable to define the closest measurement as possible of the power input and of air
inlet of the ICT equipment.
ETSI
17 ETSI ES 202 336-12 V1.2.1 (2019-02)
It is preferred to measure power inside the ICT equipment on the power input lines. If not possible it can be done
outside but always downstream interface A or A3 as defined in ETSI ETS 300 132-1 [2], ETSI EN 300 132-2 [6] and
ETSI EN 300 132-3-1 [i.15] of the considered ICT considered element under measurement.
When there are several power interface A or A3 inputs on the same ICT equipment, the sum of all power and energy
measurements shall be provided in the monitored data in addition to individual values.
The temperature and humidity in which the ICT equipment is operating, shall be taken by an external sensor located at
the air inlet of ICT equipment as defined in ETSI EN 300 019-2 series [9].
As in clause 4.3.1 for simple site, the data transmitted to the NMS shall be available on export line to another server as
specified in clause 4.5.
Figure 3: Example of cohabitation of ICT equipment internal and external power/energy/environment
measurement acquisition in a site considering 3 cases of implementations
(power frame measurement, input junction box measurements, built-in measurements)
4.4 Measurement and monitoring description
4.4.0 General description
This description of measurement is split in the 3 following clauses (clauses 4.4.1 to 4.4.3):
• downstream interface A or A3 built-in measurement for new equipment (type 1);
• upstream interface A or A3 measurement for legacy equipment (type 2);
• common requirements.
ETSI
18 ETSI ES 202 336-12 V1.2.1 (2019-02)
4.4.1 Internal measurements type 1 (Built-in in ICT equipment)
Power consumption measurement are done inside the ICT equipment.
The priority of measurement is on power inputs downstream of interface A of equipment, to be intended for the purpose
of the present document as interface A at shelf level (both for deployment in a rack or in a cabinet enclosure).
Optionally it can be provided measurement at board level.
In table 1, the power/energy/temperature measurement defined for each network element shall be applied.

power and cooling measurements to identify the equipment and its location.
The data shall be transmitted using the TMN monitoring protocol Recommendation [i.12] to the ICT management
system.
If an ICT equipment includes a power/energy/environment parameters monitoring interface, it shall be compliant to
ETSI ES 202 336-1 [1] and the present document for interoperability reason between ICT equipment or NMS and
XRMS Interoperability on the TMN is out of the scope of the present document.
ETSI
19 ETSI ES 202 336-12 V1.2.1 (2019-02)
4.4.2 External measurements type 2 (external sensors) for ICT equipment
The measurement type 2 of the ICT equipment (same list as in table 1) is done externally upstream from interface A by
the following means:
• Current, Voltage sensors or Power or Energy Meters installed in electrical junction box or final power
distribution frames or by sensors for current.
• Multi sensor Acquisition unit.
• A PEE DGU or XCU.
NOTE: Sensors or meters can be interconnected to this XCU or DGU, by a bus.
The monitoring interface at the level of the XCU or DGU is ETSI ES 202 336-1 [1] with data information model of the
present document.
Other environmental measurements (temperature, humidity) shall be associated in order to perform correlation with the
power/energy measurements on the considered equipment. The temperature or humidity sensors have to be very close to
the air inlet of this equipment, which means several measurements on a multicabinet system.
4.4.3 Common requirements for external (type 2) and internal (type 1)
measurement
4.4.3.0 Principle of PEE measurement
The principle of the measured data acquisition, of the local processing and of the robust data saving for a reliable
remote monitoring and control are described in clauses 4.4.3.1 to 4.4.3.7. More details are given in annex F on the data
measurement chain and on state of the art measurement with fair accuracy.
PEE measurement type, accuracy, test methods and data preparation for remote transmission are defined in order to
provide the mandatory monitoring/

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).

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].

4 ICT power, energy and environmental parameters
monitoring system
4.1 General description
The basic principles of power, energy and environment parameters measurements of ICT equipment (temperature,
hygrometry) and their transfer to the network management systems (NMS) are shown in figure 1.
NOTE 1: The definition of specific NMS for mobile or fixed networks is out of scope of the present document. The
same comment applies to OSS.
ETSI
13 ETSI ES 202 336-12 V1.2.1 (2019-02)
The following measuring device are used:
• wattmeter or energy meter (W, Wh); and/or
• Voltage (V); and/or
• current meter (A).
Voltage or current shall be recorded for monitoring when used to assess the power and energy consumption.
Temperature shall also be measured and recorded.
NOTE 2: The energy consumption can be calculated from power measurement over a period of time.
NOTE 3: Humidity should be measured at the level of room or air conditioning, not at equipment level.
In the preferred implementation, power and energy measurements shall be taken down-stream of power supply interface
A or A3 as defined in ETSI ETS 300 132-1 [2], ETSI EN 300 132-2 [6] and ETSI EN 300 132-3-1 [i.15] and inside the
ICT equipment (type 1 measurement).
Otherwise e.g. on legacy equipment, power and energy measurements can be taken upstream of interface A outside the
ICT equipment (type 2 measurement).
The electrical measurement sensors shall be located the closest as possible of the power electrical interface (A or A3)
and the thermal environment sensors shall be placed in the air flow of the air inlet of the equipment.
PEE measurement values can be transmitted directly from XCU or DGU to XRMS or indirectly by the NE through the
TMN protocol over the NMS to the XRMS. The direct and indirect transmission shall comply with ETSI
ES 202 336-1 [1] and the present document's protocol.
NOTE 4: The Network Management System (NMS) is the functional entity from which the network operator
monitors and controls the system at centralized level and manage operational and maintenance activities,
it is using a TMN protocol not defined in the present document. The operation and Maintenance functions
are based on the principles of the Telecommunication Management Network (TMN) of Recommendation
ITU-T M.3010 [i.12] introduced by Recommendation ITU-T M.3000 series [i.11].
NOTE 5: The measurements done using the present document can be used as inputs for enabling:
 the assessment of Power Consumption in Broadband Telecommunication Networks Equipment
[i.3], Transport Telecommunication Networks Equipment [i.6] and Customer Premises Equipment
(CPE) [i.8];
 the assessment of Energy efficiency of wireless access network equipement [i.4], Core network
equipment [i.5], router and switch equipment [i.7] and Mobile Network [i.10];
 the power management capabilities of the future energy telecommunication fixed network nodes
with Green Abstraction Layer (GAL) [i.9].
ETSI
14 ETSI ES 202 336-12 V1.2.1 (2019-02)

NOTE 1: In figure 1, some ICT sites may not have all of the parts (building, power, cooling) and therefore monitoring
interface would not be required.
NOTE 2: An ICT equipment of a vendor X is in general connected to the NMS of the vendor X, but the power/air
conditioning /building infrastructure XRMS can be from a vendor Y.

Figure 1: Principle of the monitoring of ICT equipment power, energy and environment parameters
4.2 Complementarity to existing site power and air-conditioning
measurements
The power/energy and environmental (PEE) parameters measurement on ICT equipment as standardized in the present
document are complementary to the measurements defined at the site and room level on the power and air conditioning
systems introduced in standard ETSI ES 202 336-1 [1].
In particular the standard ETSI ES 202 336-2 [3], ETSI ES 202 336-3 [4], ETSI ES 202 336-4 [7], ETSI
ES 202 336-6 [8] and ETSI ES 202 336-10 [5] shall be used for definition of PEE measurements monitored by non ICT
equipment in telecommunications or datacenter or customer premises (e.g. power, cooling and distributions systems):
• AC and DC current, voltage and or power sensors;
• AC and DC energy meters;
• Voltage, current, AC frequency measurement sensors;
• True Power factor measurement device;
NOTE 1: The true Power Factor includes the AC Displacement Factor (i.e. the cosinus of the phase angle between
AC current and voltage of 50 Hz fundamental signals) and the current Distorsion Factor. The current
distorsion is the highest factor for ICT load powered by SMPS as phase angle is close to 0. The distortion
factor is a measurement of the performance of the PFC (Power Factor Correction) function.
ETSI
15 ETSI ES 202 336-12 V1.2.1 (2019-02)
• Sensors bus e.g. for power metering;
• Additional measurements.
NOTE 2: For very critical site, there could be additional power quality monitoring measurements (e.g. harmonic
currents amplitude, power factor, distorsion, dips, etc.) as defined in ETSI ES 202 336-4 [7].
NOTE 3: All the PEE measurements transmitted through ETSI ES 202 336 (all series) [i.16] can be used to get
measurements complementary to those defined in the present document e.g. DC current or power
measurement compliant to ETSI ES 202 336-2 [3] at the output of a DC system supplying one or several
ICT equipment.
4.3 Different site cases
4.3.1 Simple site case
Two types (see figure 2) of PEE monitoring can exist in a simple ICT site, and the compatibility is ensured between
these types with the remote monitoring:
• Type 1: built-in measurements inside ICT equipment down-stream from interface A (or A3).
• Type 2: external measurement at input junction box measurements up-stream from interface A (or A3).
Internal power consumption and environment sensors and external measurement connected to an energy
metering/environment XCU shall be used as defined in clause 4.4. Humidity measurements are optional.
Data export from NMS to the power/cooling remote management server shall use the ETSI ES 202 336-1 [1] and the
present document. The NMS can also be used for dialog with other type of server as explained in clause 4.5.
ETSI
16 ETSI ES 202 336-12 V1.2.1 (2019-02)

Figure 2: Example of possible implementation in a simple Telecom site
(e.g. a radio mobile site with ICT/Telecom connected to an OSS/NMS)
4.3.2 Complex site case
Figure 3 gives example of 3 cases of monitoring of PEE that can exists in a complex ICT site, and how compatibility is
ensured between these cases with the remote monitoring:
• Type 1: built-in measurements inside ICT equipment down-stream from interface A (or A3).
• Type 2: external measurement at input junction box measurements up-stream from interface A (or A3).
• Type 3: power frame measurement at output of power supply system.
On complex big sites with many equipment from different manufacturers and of different types, users require power
and energy measurement of each ICT equipment and the global monitoring provided in power and air-conditioning is
not sufficiently accurate.
For measurement on the power system and power distribution frame, the issue is to manage on the long run the cabling
tracing and identification to be sure that the measurement always corresponds to the same considered ICT equipment. It
often happen that a power output cable is common to several equipment, powered in room through a secondary
distribution cabinet with smaller cables. With redundancy and double distribution from separate sources it is even more
complicated. In addition the distribution is changing with the evolutive life of the site.
For air condition, this can happen that the sensors are not located close enough to the ICT equipment so that the sensor
does not reflect the condition really seen by the ICT equipment.
So it seems much more reliable and stable to define the closest measurement as possible of the power input and of air
inlet of the ICT equipment.
ETSI
17 ETSI ES 202 336-12 V1.2.1 (2019-02)
It is preferred to measure power inside the ICT equipment on the power input lines. If not possible it can be done
outside but always downstream interface A or A3 as defined in ETSI ETS 300 132-1 [2], ETSI EN 300 132-2 [6] and
ETSI EN 300 132-3-1 [i.15] of the considered ICT considered element under measurement.
When there are several power interface A or A3 inputs on the same ICT equipment, the sum of all power and energy
measurements shall be provided in the monitored data in addition to individual values.
The temperature and humidity in which the ICT equipment is operating, shall be taken by an external sensor located at
the air inlet of ICT equipment as defined in ETSI EN 300 019-2 series [9].
As in clause 4.3.1 for simple site, the data transmitted to the NMS shall be available on export line to another server as
specified in clause 4.5.
Figure 3: Example of cohabitation of ICT equipment internal and external power/energy/environment
measurement acquisition in a site considering 3 cases of implementations
(power frame measurement, input junction box measurements, built-in measurements)
4.4 Measurement and monitoring description
4.4.0 General description
This description of measurement is split in the 3 following clauses (clauses 4.4.1 to 4.4.3):
