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 ETSI ES 202 336-12 V1.2.1 (2019-02)

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.

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].

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)

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].

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
