Receives Certification from ENERGY STAR® for Environmentally-Friendly Devices; Publishes Green Ethernet Technology White Paper

FOUNTAIN VALLEY, Calif., October 24, 2007 — D-Link, the end-to-end networking solutions provider for consumer and business, today announced the introduction of the industry's first Green Ethernetâ„¢ technology with a new series of environmentally-friendly small office/home office (SOHO) Gigabit switches that decrease energy costs by reducing power consumption without sacrificing operational performance and functionality.

The introduction of the D-Link® DGS-2200 series multi-port desktop switches is part of an ongoing company-wide 'Green' computing initiative that includes manufacturing environmentally-responsible products, optimizing devices for ENERGY STAR certification, providing consumer education and recycling programs, and distributing the network technology industry brief titled "Green Computing and D-Link: The Green Movement and Specific D-Link Solutions Reduce Detrimental Impacts on the Environment."

In November, D-Link will broaden the program by adding its energy-efficient DGS-1016D 16-port and DGS-1024D 24-port high performance rack mountable switches to its 'Green' technology lineup.

D-Link's Green Ethernet switching solutions provide an opportunity for significant energy savings. For example, when connected and subsequently powered down, the DGS-2208 multi-port desktop switch can realize up to 80 percent savings in power usage*, and the other D-Link 'Green Ethernet' switches can save up to 45 percent in power usage. The same devices, when connected via Ethernet cables and used for 10 hours and then powered down for 14 hours over a 24-hour period, provide up to a 40 percent and 27 percent energy reduction, respectively**.

About D-Link's Green Ethernet Technology

D-Link's Green Ethernet technology conserves energy by recognizing when a port is active or inactive then adjusts its power accordingly, benefiting Home/SOHO users who may not need perpetual use of their computers or the use of all the ports on their switches. It is also capable of altering power usage in relation to the length of its Ethernet cable, conserving energy use and benefiting both the user and the environment without any loss of performance.

  • Power conserved when links are idle
    Even when a computer is shut down, switches often remain on and continue to consume considerable amounts of power. Through D-Link's Green Ethernet technology, the new switches can detect when a computer is turned off and will respond accordingly by powering down the corresponding port into standby mode and reducing power used for that port.
  • Optimized power usage based on dynamic detection of cable length
    Normally, switches send full power to Ethernet cables regardless of the actual length of the cable. Through D-Link's Green Ethernet technology, the switches are able to analyze the cable's length and adjust the power accordingly. Since the cable length used by Home/SOHO users is mostly less than 20m, power consumption can be significantly reduced.

The incorporation of Green Ethernet technology into these DGS-2200 series switches re-emphasizes D-Link's strong commitment to protecting the environment, leading the development of eco-friendly products that comply with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) directives. The RoHS directive restricts the use of specific hazardous materials during the manufacture of electrical and electronic goods while WEEE applies standards for proper disposal and recycling of products.


As part of its ongoing program to manufacture environmentally-friendly products, D-Link has become a partner with ENERGY STAR, a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DoE) to promote energy conservation and management best practices.

For businesses, ENERGY STAR takes a strategic approach to energy management that produces twice the savings – for the bottom line and the environment – by offering an energy management strategy that helps measure current energy performance, establish goals, track savings and gain rewarding improvements.

"The safety and integrity of our products are of great concern to us and key to our relationship with customers," said Steven Joe, president and CEO of D-Link Systems, Inc. "We're proud to introduce the industry's first Green Ethernet products and to be an ENERGY STAR partner.

"We will continue to seek new avenues that protect the environment and help consumers save money by offering energy efficient products." Joe added.

"We salute D-Link's leadership in this important energy-saving initiative," said Steve Ryan, EPA ENERGY STAR Program Manager. "D-Link is the first manufacturer to qualify adapters that are used by routers, firewalls, and Internet cameras for the ENERGY STAR program. By conserving energy, ENERGY STAR-qualified adapters help reduce greenhouse gas emissions and air pollution associated with the generation of electricity."

D-Link's Commitment to the World Environment

  • D-Link is designing consumer and business products to shut down or reduce power consumption when not in use. The IEEE (Institute of Electrical and Electronics Engineers, Inc.) is developing the 802.3 specifications for Energy Efficient Ethernet that may be standardized by 2012. However, D-Link plans to introduce within the next year auto-sensing capabilities so products detect when to power down and save energy.
  • D-Link consumer product gift boxes are made of recycled materials, with the eventual goal of all packaging to be made of recycled materials.
  • D-Link participates in the Returned Merchandise Association (RMA), a program that converts returned merchandise into products that can be resold and reused.
  • D-Link's manufacturing responsibility includes factory compliance with ISO 14001, an internationally accepted specification for an environmental management system (EMS). It specifies requirements for establishment of an environmental policy, determining environmental aspects and impacts of products/activities/services, plans for environmental objectives and measurable targets, implementation and operation of programs to meet objectives and targets, checking and corrective action, and management review.
  • As part of its ISO 14001 compliance, D-Link pledges to conform to all legal and other requirements related to the protection of the environment, minimize adverse impacts to the environment, promote 'Green' products, save energy and scarce resources, take preventive actions to protect the environment and maintain a safety-first and health-first policy for employees.
  • D-Link has also earned ISO 9001 certification, which designates that the Company has defined processes for establishing and maintaining an effective, quality system for manufacturing. This certification outlines a guide for quality products and has become an international reference for quality requirements in business-to-business dealings.
  • D-Link has actively recruited recycling partners in North America to take in and properly dispose of unused networking products, a service that provides customers an easy way to properly dispose of and recycle old switching equipment.
