D-Link's Energy Saving Claims for Green Ethernet Products Verified by Independent Testing Lab

Nov. 20, 2008 - PRLog -- LONDON, UK – D-Link has today announced results of a power consumption test - conducted by Broadband-Testing Labs - validating its claims that its Green Ethernet switches deliver true energy savings. D-Link was first to market with Green Ethernet products last year; now, as an increasing number of commercial and public sector organisations are taking proactive measures to reduce their energy consumption, D-Link is the first network vendor to have its energy-saving claims independently validated.

Steve Broadhead, Director Broadband-Testing Labs, said “Not only are the consumption figures well below any published figures currently available, but are below those D-Link itself made available from internal testing. The figures include full line rate traffic testing, itself a testament to the ability of the D-Link switches, given their competitive pricing, to be able to perform at full line rate.” Broadhead added, “D-Link was first to market with Green Ethernet products and made claims about energy-efficiency that have been validated by these tests.”

The research results provide current and potential D-Link customers with the reassurance that with its Green Ethernet switches, it is not paying lip-service to the current environmental zeitgeist, but actually creating products that deliver measureable energy savings.

Nigel Moulton, VP Enterprise and SME, D-Link Europe, said, “Going green and reducing power consumption is an absolute requirement for many customers, so products must deliver on their green promise. As such, we are delighted that these tests confirm the unique energy-saving capability of D-Link’s business-class switches; an achievement that has not come at the expense of the switches’ performance or price point.”

Under test was D-Link’s DGS-1224T 24-port Green Ethernet Gigabit Smart Switch, which is D-Link’s entry point into energy saving networking for the SMB market. Equipped with D-Link Green Ethernet technology, the switch reacts when a device attached to it is turned off, by placing the corresponding port in a standby mode that requires less power. The switches also detect cable lengths and adjust power output accordingly.

In the power consumption testing the DGS-1224T recorded consumption figures amounting to less than a watt of power required to drive over a gigabit per second throughput. Typically, even a 10/100 switch (without gigabit) would use 50-100% more power in basic operational mode. The DGS-1224T was tested on its gigabit port active/inactive control to see how much power the device consumes. In Green Ethernet mode, power consumption was reduced from 20.7 watts (24 ports enabled, no traffic) to 9.3 watts. To put this into some perspective, PCs in standby mode can consume between 10 and 15 watts, according to the BBC. This highlights the benefit of being able to configure gigabit ports to be inactive by default – rather than the industry standard default of being active whenever the switch is powered up.  

In order to measure for all user type scenarios, the DGS-1224T was loaded as heavily as possible with full port capacity. Broadband-Testing Labs was impressed to record full line rate capabilities at Gigabit speeds, especially considering the very competitive pricing of the switch. During the test, the D-Link switches proved to be very power efficient, and ran perfectly at line speed at gigabit and 10gigabit speeds.
