CSA C872:14 (R2019)

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. 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. 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.
