TRENDnet, a provider of networking solutions, has introduced four new GREENnet switches, 16-Port 10/100Mbps GREENnet switch (model TE100-S16g), 24-Port 10/100Mbps GREENnet switch (model TE100-S24g), 16-Port Gigabit GREENnet Switch (model TEG-S16g) and 24-Port Gigabit GREENnet Switch (model TEG-S24g). Each switch uses integrated energy saving GREENnet technology.

GREENnet is a TRENDnet switch-based technology that determines and supplies the suitable amount of electrical power to each hardwired switching port as essential by the connected device, by the port, or by the length of the connected Ethernet cable. GREENnet technology can lessen the given device’s power consumption by up to 70%.

GREENnet solutions automatically detect if an Ethernet port is not in use and will lessen the amount of power sent to the respective unused port. A port may not be in use when either no device is connected to the port or when the device that is connected to the port is powered down or in Standby Mode. Regular switches do not have this capability, and therefore consume more power while performing the same networking function.

Less power is essential to send data over shorter cable lengths. GREENnet technology automatically detects the length of the cable that connects the Ethernet port to the networked device and adjusts the power supply accordingly. This technology functions automatically, requires no management and has no effect on product performance.

Energy savings generated by the switch vary depending on switch loading and the cost of electricity for a given location. Primary testing discloses that under moderate loading scenarios the 16 and 24 port 10/100Mbps GREENnet Switches can yield energy savings between $5 – $10 per year and the 16 and 24 port Gigabit GREENnet Switches can yield energy savings between $10 – $20 per year with an assumed electrical cost of $0.15 per kilowatts hour.

TRENDnet’s GREENnet(TM) technology is a seamless solution that reduces power consumption without affecting product performance. No management is required, it simply works when you turn on the device, stated Zak Wood, director of global marketing for TRENDnet. TRENDnet first integrated GREENnet(TM) technology into our wireless n routers in October of 2008. The cumulative energy savings of all of GREENnet switches sold will produce a measured and important benefit.
