Large Network Equipment Key Product Criteria

ENERGY STAR certified large network equipment (LNE) products must use efficient power supplies. Below we provide an overview of the key efficiency and power factor criteria for the power supplies in Table 1 and Table 2.  Please read the specification (PDF, 801KB) for a complete description of the requirements for certification.

Table 1: Efficiency Requirements for all PSUs

Power Supply Type	Rated Output Power	10% Load	20% Load	50% Load	100% Load
Multi-output	All output levels	N/A	85%	88%	85%
Single- output	All output levels	80%	88%	92%	88%

Table 2: Power Factor Requirements for AC-DC PSUs

Power Supply Type	Rated Output Power	10% Load	20% Load	50% Load	100% Load
Multi-output	All output levels	N/A	0.80	0.90	0.95
Single- output	≤ 500 W	N/A	0.80	0.90	0.95
Single- output	1000 W≥ output rating> 500 W	0.65	0.80	0.90	0.95
Single- output	>1000 W	0.80	0.90	0.90	0.95

ENERGY STAR certified LNE must have the following energy efficient features:

• Remote Port Administration: An LNE product must provide the end-user with the ability to conduct remote administration of individual physical network ports.
• Adaptive Active Cooling: Primary components of an LNE product must utilize adaptive cooling technologies that reduce the energy consumed by the cooling technology in proportion to the current cooling needs of the LNE product. (e.g., reduction of variable speed fan or blower speeds at lower ambient air temperature). This requirement is not applicable to devices that employ passive cooling.
• Energy Efficient Ethernet: All copper-based physical network ports in an LNE product must be compliant with IEEE 802.3 Clause 78.

In addition, for products with a nameplate power rating greater than 250 watts, real-time reporting of input power and air inlet temperature is required.

Finally, active state data reporting of power and performance is required.
