CSA Group CSA C872:14 National Standard of Canada (reaffirmed 2024) Power consumption of small network equipment (SNE)

Preface

This is the first edition of CSA C872, Power consumption of small network equipment (SNE).

This Standard specifies the test method for measuring and reporting the power consumption of small network equipment.

This Standard has been harmonized with the requirements for testing and evaluating the power consumption of small network equipment specified in the Energy Star Small Network Equipment Specification, Version 1.0 (revised November 2013).

CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Ontario Ministry of Energy, BC Hydro, Natural Resources Canada (NRCan), Efficiency Nova Scotia, Manitoba Hydro, Sask Power, and the Ontario Power Authority.

The Standard was prepared by the Subcommittee on Energy Efficiency for Small Network Equipment, under the jurisdiction of the Technical Committee on Residential Equipment and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Notes:

1)  Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2)  Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3)  This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

4)  To submit a request for interpretation of this Standard, please send the following information to [email protected] and include “Request for interpretation” in the subject line:

a) define the problem, making reference to the specific clause, and, where appropriate, include a graphical image;

b) provide an explanation of circumstances surrounding the actual field condition; and

c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

Committee interpretations are processed in accordance with CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.csagroup.org.

5)  This Standard is subject to review within five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to [email protected] and include “Proposal for change” in the subject line:

a) Standard designation (number);

b) relevant clause, table, and/or number;

c) wording of the proposed change; and

d) rationale for the change.

Scope

1.1

This Standard specifies the test method for measuring and reporting the power consumption of small network equipment.

Note: This Standard is technology neutral.

1.2

The following products are not covered by this Standard:

a) network equipment capable of accepting interchangeable modules, such as line cards or additional power supplies;

b) network equipment with one or more network ports using pluggable or modular media adapters such as Gigabit Interface Convertor (GBIC) or Small Form-factor Pluggable (SFP) modules. This does not include USB ports;

c) network equipment whose primary wireless capability is not IEEE 802.11 (Wi-Fi);

d) network equipment that receive direct dc power (PoE, USB) or provide power through PoE;

e) large network equipment; and

f) network equipment that is marketed and sold as enterprise network equipment and can be controlled and configured for operation by an external controller.

1.3

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.4

The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
