D-Link has launched another green product, this time its a 5-port Gigabit switch that promises a 73 percent reduced power consumption without sacrificing network performance.
Shipping now, the DGS-2205 is one of four environmentally friendly small office/home office (SOHO) unmanaged gigabit switches that will ship this year with newly enhanced power-savings. The next-generation D-Link 8-Port Gigabit Desktop Switch (DGS-2208). The 16-port (DGS-1016D) and 24-port (DGS-1024D) unmanaged gigabit switches will also receive enhanced power-savings later this year.

The second-generation releases of the D-Link DGS-2200 series multi-port desktop switches are part of an award-winning company-wide D-Link Green™ technology computing initiative that includes manufacturing environmentally-responsible products, eco-friendly packaging, optimizing devices for ENERGY STAR certification, and providing consumer education and recycling programs.

When connected and powered down, the DGS-2205 D-Link Green switch can save up to 73 percent when compared with non-Green D-Link conventional switches.

The same device, when used for 10 hours and then powered down for 14 hours over a 24-hour period, when connected via Ethernet cables, represents a 66 percent energy reduction.
Power saving equals cost saving with the new second generation D-Link with MSRP prices set at $59.99 for the DGS-2205 and $79.99 for the DGS-2208. MSRP pricing of the DGS-1016D and DGS-1024D are $219.99 and $249.99 respectively.



D-Link's Green 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 cable, conserving energy use for 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 Green technology, the new switches can detect when a computer is turned off and will respond accordingly by powering down 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 cables regardless of the actual length. Through D-Link's Green 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.
