regulation, the motherboard includes connectors for attaching additional boards 
and typically includes the following components: processor, memory, BIOS, 
and expansion slots ; 
(4) ‘processor’ means the logic c ircuitry that responds to and processes the basic 
instructions that drive a server. For purposes of this regulation, the processor is 
the CPU of the server. A typical CPU is a physical package to be installed on 
the server motherboard via a socket or direc t solder attachment. The CPU 
package may include one or more processor cores ; 
(5) ‘memory’ means a part of a server external to the processor in which 
information is stored for immediate use by the processor ;

share processors that plug into a common socket type;  
(d) share the power s upply unit(s) ;  
(14) 'power supply unit' (PSU) means a device that converts alternate current (AC) 
or direct current (DC) input power to one or more DC power outputs for the

total rated power output from any additional PSU outputs that are not primary 
and standby outputs shall be no greater than 20 Watts. PSUs that offer multiple

Measurements and calculations  
1. For the purposes of compliance and verification of compliance with the applicable 
requirements of this Regulation, measurements and calculations shall be made using 
harmonised standards, the reference numbers of whic h have been published in the

which includes both hardware configuration and system settings, unless otherwise 
specified.   
For servers with expansion APA, the unit under test shall be tested with the

and the server performance in active state . 
For multi -node servers , the unit under test shall be tested for per node power 
consumption in the fully -populated chassis configuration.  
For blade server s, the unit under test shall be tested for blade server power 
consumption in the half -populated chassis configuration, and the chassis shall be

single -wide blade server slots available in the blade chassis shall be 
calculated.  
(b) For blade  chassis having multiple power domains, the number of power 
domains that is closest to filling half of the chassis shall be chosen. If 
there are two choices that are equally close to filling half of the chassis, 
the test shall be performed with the domain or combination of domains 
which use a higher number of blade servers.  
(c) All user manual or manufacturer recommendations for partially 
populating the chassis, which may include disconnecting some of the 
power supplies and cooling fans for the unpopulated pow er domains, 
should be followed.  
(d) If user manual recommendations are not available or are incomplete, then 
the following guidance shall be used:  
(i) Completely populate the power domains;  
(ii) If possible, disconnect the power supplies and cooling fans for  
unpopulated power domains;

airflow restriction for the duration of testing.  
   
EN 12  EN ANNEX IV  
Verification procedure for market surveillance purposes  
The verification tolerances defined in this Annex relate only to the verification of the 
measured parameters by Member State authorities and shall not be used by the manufacturer 
or importer as an allowed tolerance to establish the values in the technical documentation or 
in interpreting these values with a view to achieving compliance or to communicate better 
performance by any means.  
Where a model has been designed so that a model's performance is automatically altered in 
test conditions with the objecti ve of reaching a more favourable level for any of the 
parameters specified in this Regulation  or included in the technical document ation provided 
with the product, the model shall be considered not compliant.  
When verifying the compliance of a product mode l with the requirements laid down in this 
Regulation pursuant to Article 3(2) of Directive 2009/125/EC, for the requirements referred to 
in this Annex, the authorities of the Member States shall apply the following procedure:  
1. The Member State authoritie s shall verify one single unit of the model or model 
configuration.  
2. The model or model configuration shall be considered to comply with the applicable 
requirements if:  
(a) the values given in the technical documentation pursuant to point 2 of Annex 
IV to Di rective 2009/125/EC (declared values), and, where applicable, the 
values used to calculate these values, are not more favourable for the 
manufacturer or importer than the results of the corresponding measurements 
carried out pursuant to paragraph (g) there of; and  
(b) the declared values meet any requirements laid down in this Regulation, and 
any required product information published by the manufacturer or importer 
does not contain values that are more favourable for the manufacturer or 
importer than the declar ed values; and  
(c) when the Member State authorities test the unit of the model or model 
configuration, the determined values (the values of the relevant parameters as 
measured in testing and the values calculated from these measurements) 
comply with the respe ctive verification tolerances as given in Table 7.  
3. If the results referred to in points 2(a) or 2(b) are not achieved, the model and all 
model configurations that are covered by the same product information (according to 
Annex II point 3.1(n)) shall be considered not to comply with this Regulation.  
4. If the result referred to in point 2(c) is not achieved:  
(a) for models that are produced in quantities of less than five per year, the model 
and all model configurations that are covered by the same product in formation 
(according to Annex II point 3.1(n)) shall be considered not to comply with this 
Regulation;  
(b) for models that are produced in quantities of five or more per year, the Member 
State authorities shall select three additional units of the same model o r model 
configuration for testing.  
5. The model or model configuration shall be considered to comply with the applicable 
requirements if, for these three units, the arithmetical mean of the determined values 
complies with the respective verification toler ances given in Table 7 .  
EN 13  EN 6. If the result referred to in point 4(b) is not achieved, the model and all model 
configurations that are covered by the same product information (according to Annex 
II point 3.1(n)) shall be considered not to comply with this Reg ulation.  
7. The Member State authorities shall provide all relevant information to the authorities 
of the other Member States and to the Commission without delay after a decision 
being taken on the non -compliance of the model according to points 3 and 6.  
The Member State authorities shall use the measurement and calculation methods set out in 
Annex III.  
The Member State authorities shall only apply the verification tolerances that are set out in 
Table 7 of this Annex and shall only use the procedure describ ed in points 1 to 7 for the 
requirements referred to in this Annex. No other tolerances shall be applied.
