D-Link has expanded its range of Green Ethernet technology with the introduction of new environmental-friendly 16- and 24-port Gigabit switches that decrease carbon emissions and energy costs by reducing power consumption without sacrificing operation performance and functionality.

The new energy-efficient DGS-1016D 16-port and DGS-1024D 24-port high performance desktop or rack mountable switches bring the benefits of D-Link’s Green Ethernet technology line to small and medium sized organisations.
“We encourage organisations to do the right thing by considering their carbon footprint when purchasing new networking products,” says Tobie van Schalkwyk, country manager for D-Link in South Africa. “With our Green Ethernet technology, small to medium sized organisations can reduce their carbon emissions and energy costs by purchasing green Gigabit switches that cost no more than comparable non-green technology.”
D-Link's Green Ethernet technology conserves energy by recognising when a port is active or inactive to adjust its power accordingly, cutting energy consumption for organisations that do not need perpetual use of their computers or all the ports on their switches. It is also capable of altering the power usage relative to the length of its cable, and conserving the use of energy for both the user and the environment without suffering any loss of performance.
For a traditional switch, power consumption remains constant even when the ports are not in use. In a standard workday scenario where PCs are used for 10 hours a day and powered off 14 hours a day, and connected to the switch using 20 metre cables, D-Link's Green Ethernet can save up to 25% power used for each system.
-link's Green Ethernet technology can detect a link's status and cable length, and adjust power usage accordingly. By reducing power consumption, less heat is produced, resulting in extended product life and lower operating costs.
Even when a computer is shut down, switches often remain on and continue to consume considerable amount of power. Using D-link's Green Ethernet technology, the new switches can detect when a computer is turned off, and then respond accordingly by changing into power standby mode, thus reducing power usage for that port.
Switches normally send full power to cables regardless of the actual length. Using D-link's Green Ethernet technology, the switches can analyse the cable's length and adjust the power accordingly. Since the cable length used by small to medium organisations is often less than 20m, power consumption can be significantly reduced.
Both the DGS-1016D 16-port and DGS-1024D 24-port Gigabit switches feature a non-blocking switching architecture that filters and forwards packets at full wire-speed for maximum throughput. An 8K MAC address table provides scalability for even the largest networks. Address learning and aging, 802.3x Flow Control for full-duplex mode, and back pressure flow control for half-duplex mode alleviates traffic congestion and ensures reliable data transmission.
Designed using industry standards, both new Green Ethernet switches are compatible with virtually all 10Mbps, 100Mbps, and 1000Mbps Ethernet devices and other vendor equipment, protecting existing network investments while providing a straightforward migration path to faster Gigabit speeds.
