Feature Dependencies
There are no dependencies to other features.
Hardware
Energy metering is supported on all Baseband units. However, the power
measurements reported on the Baseband 6303 and Baseband 6502 do not cover
the PSU and the fan.
Energy metering is not supported on DUs.
All internal radios, RRUs, and AIRs support energy metering, except the
following:
— AIR 11, AIR 21, AIR 32
— RRUS A2, RRUS 01, RRUS 02, RRUS 11, RRUS 32, RRUS 61, mRRUS 12,
mRRUS 61, RRUS 72, RRUS 82
— RUS 01, RUS 02
— RUL 01
— RUW 01, RUW 02
— RRUW 01, RRUW 02, RRUW 03
— RIR 11, RIR 12, RIR 14
— IRU 2242
Energy metering is supported on the following support system units:
— PDU 03 02, PDU 03 01
— PSU AC 03
— EMU
Energy metering is not supported on the following support system units:
— BFU 01 02, BFU 01 03
— PDU 01 01, PDU 01 03, PDU 01 04, PDU 02 01, PDU 02 02
— PSU AC 01
— SAU 01 01, SAU 02 01

231/221 04-LZA 701 6014/1 Uen BT13A | 2020-11-06
— SCU 01 01, SCU 02 01, SCU 03 01
Limitations
— The PM counters under the EnergyMeter MO for RBS 6501 show the
consumption of the integrated radio unit, not the whole RBS. To see the
consumption of the whole RBS 6501, legacy counters under the MO
EnergyMeasurement must be used instead.
— The measurement of the power consumption of the radio unit includes the
power consumption of RET and TMA equipment with power supply from a
radio unit.
— The pmVoltage counter under the EnergyMeter MO reports only in absolute
values.
— Up to 150 active EnergyMeter MOs are supported on a node. From these,
maximum 50 can be consumer units, including both radio units and
baseband units.
Network Requirements
There are no network requirements for this feature.

Feature Operation of Energy Metering
The Energy Metering feature provides a standardized way to observe power
consumption and energy consumption of Baseband and radio units.
Measurements are presented with PM counters under the following MOs:
— EnergyMeter
— ConsumedEnergyMeasurement for Baseband units
— ConsumedEnergy for DUs
— EnergyMeasurement
The PM counters are activated automatically, except those that are under the
EnergyMeasurement MO, where manual configuration is needed.
The EnergyMeter MO is automatically created and enabled for each supported
Baseband, radio unit, and installed support system unit (PSU, PDU, and EMU) of
a node. It can be manually enabled or disabled with
EnergyMeter.setEnergyMeterEnabled for example, if the maximum number of
active EnergyMeter MOs is reached.
For Baseband units, the ConsumedEnergyMeasurement MO automatically
summarizes the power consumption of all active EnergyMeter MOs representing
Baseband and radio units.
For DUs the ConsumedEnergy MO automatically summarizes the power
consumption of all active EnergyMeter MOs representing radio units.
The EnergyMeasurement MO can be configured to summarize the power
consumption of active EnergyMeter MOs for support system units representing
PSUs, EMUs or PDUs, that is, e-fuses. For example, several EnergyMeasurment
MO instances can be created to summarize the power consumption of different
parts of the Modular PDU System (e-fuses).

Overview of Energy Consumption Measurement
Aggregation
On a site with Ericsson power system, energy consumption can be measured on
the following levels:
— Site level - AC-fed cabinet
The incoming AC voltage energy consumption in a cabinet can be measured
by aggregating the energy meters from the installed PSUs. The units to be
included in the measurement are configured in the EnergyMeasurement MO.
— Site level - DC-fed cabinet
The DC voltage energy consumption can be aggregated for several PDUs
including all e-fuses, selected e-fuses, or EMUs. The units to be included in
the measurement are configured in one or several EnergyMeasurement MOs.
— Equipment level - consumer units
The energy consumption of Baseband units and radio units that support the
EnergyMeter MO is automatically aggregated by the
ConsumedEnergyMeasurement MO (for Baseband units) and the
ConsumedEnergy MO (for DUs).

energy consumption of one of the following units:
— An RBS cabinet
— A selected number of consumer units that are supplied with power by the

Ericsson Energy Report
The Ericsson Energy Report feature is a guided analysis. It is intended to give the
user an overview of power use, energy consumption and data volumes for the top
100 consuming nodes. The details are on EnergyMeter MO-level.

Energy Metering
The analysis allows for search and grouping of nodes for comparison in the
network. Detailed analysis of the benefits and effects of various energy saving
features on data volumes and energy consumption is available.
The Energy Report supports ranking and searching of nodes across the following
radio nodes visible to an ENIQ-S deployment:
— NR
— LTE ERBS
— WCDMA RBS
— LTE
— WCDMA
— GSM
The analysis retrieves, queries, and visualizes data for the previous seven-day
period for the Ranking, Search and Energy Saving flows.
For the Energy Usage flow, the analysis retrieves and visualizes data for up to the
previous three years.
The report supports the pmConsumedEnergy counter on both the
EnergyMeasurement and the EnergyMeter MOs, as well as data volume and
energy saving counters.

Activate Basic Feature
This is a basic feature. It does not require manual activation and cannot be
deactivated.
While optional features need to be activated, basic features are activated
automatically during node integration. They also do not have a software license
key associated, which means that they have no entries in the LKF that is installed
on the node.
It is possible that some functions of basic features need to be enabled or
configured manually.
