D-Link Green Technology
D-Link Green Technology includes a number of innovations to reduce energy consumption:
What constitutes a D-Link Green product?
The D-Link Green line of products was launched to ensure that the company's sustainability and corporate responsibility goals were being met. Due to the wide variety of products that we make, innovation is key to our success in utilising D-Link Green Technology across a number of platforms. D-Link Green standards ensure that consumers are receiving a standardised set of Green features. Our goal is to have 80% of all our products "D-Link Green" certified by 2012.
To qualify for a D-Link Green label, a product must meet the following criteria:
- include at least one energy-saving feature among those listed under "D-Link Green technologies"
- comply with initiatives such as ENERGY STAR (if applicable), WEEE and RoHS
- use eco-friendly, sustainable packaging solutions
Power savings by number of connected ports and link status
Computers do not require Internet access all the time; neither do switches utilise all ports at all times. When a computer or network equipment is shut down, switches often remain on and continue to consume considerable amounts of power. For these conventional switches, power consumption remains constant even when the ports are not in use.
Switches equipped with D-Link Green technology can automatically detect link status and reduce power usage of ports that are idle: if there is no cable link or link partners turn off, D-Link Green technology will put that port in a "sleep mode," reducing power used for that port and saving energy.*
Power savings by cable length
Most desktop switches by default assume the maximum Ethernet cable length of 100m. However, research shows that the average home uses only 5-10m of network cable. Shorter lengths require less power.
D-Link Green switches are able to detect the Ethernet cable length and adjust power usage accordingly, hence saving energy which would otherwise dissipate as heat.
In a standard workday scenario where PCs are used for 10 hours a day, powered off 14 hours a day, and connected to the switch using 20 meter cables, D-Link Green Technology can save up to 66% power used for each system (savings vary depending on switch used).
Note: When using 20m cables and DGS-1005D.
Schedule-based Power over Ethernet (PoE)
Power over Ethernet (PoE) technology enables the supply of power to network devices over traditional LAN cabling, improving flexibility in the deployment of devices. If a PoE camera or Access Point has been placed in an awkward or inaccessible location with the help of PoE, it cannot easily be switched off. Schedule-based PoE allows you to configure the times when the power should be delivered, reducing the total energy consumption.
Most of the power in Wi-Fi devices is used by the radio: even when data is not transmitted or received, the radio keeps scanning the environment for potential client devices to associate with. Routers with D-Link Green Technology let you schedule Wi-Fi only when you need it. For example, you could set the WLAN to turn itself off at night to save power.
Storage enclosures with D-Link Green Technology power down the hard drive(s) when not in use to save power.
Photo frames with D-Link Green Technology shut down when no one's around to watch.
PowerLine adapters with D-Link Green Technology turn themselves off when you are not sending data.
Low system temperatures
Storage enclosures with D-Link Green Technology take their own temperature and adjust the fan speed to provide only the cooling that is needed.
*Computers or any connecting parties set to standby mode -not power off-, however, will not provide significant power savings.
