D-Link announced a new lineup of Ethernet desktop switches that use 44 percent less electricity than its current 5-port switches. The firm claims it's the first manufacturer of such green Ethernet switches:
The power saving is accomplished in two ways. First, the new switches measure when PCs connected to them are turned off and then power down into standby mode. Secondly, they analyze cable lengths and can adjust power usage for different cable lengths accordingly. Most existing switches are powered up to support 100m cable lengths all the time, but many small systems use only 5-10m of cable.
D-Link says it is tuned into the green zeitgeist with Osbert Ong, its European product manager saying: "D-Link recognizes the significant market demand for energy-efficient networking products and is leading the initiative in making Green Ethernet a reality for the home and SME user."
Concerning larger businesses he said: "D-Link's Green Ethernet solutions will enable them to reduce their carbon footprint."
