• Efficient D-Link Green Technology
As a concerned member of the global community, D-Link is devoted to providing eco-friendly
products. D-Link Green Wi-Fi and D-Link Green Ethernet save power and prevent waste. The
D-Link Green WLAN scheduler reduces wireless power automatically during off-peak hours.
Likewise the D-Link Green Ethernet program adjusts power usage based on the detected cable
length and link status. In addition, compliance with RoHS (Restriction of Hazardous Substances)
and WEEE (Waste Electrical and Electronic Equipment) directives make D-Link Green certified
devices the environmentally responsible choice.
