D-Link introduces Green Ethernet

D-Link unveiled a new Green Ethernet technology to reduce power consumption of its switches:
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-1024 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.
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.
