1. Link Down Detect
A TRENDnet GREENnet switch will detect if an Ethernet port is not in use and will reduce the power sent to the given port. A port may not be in use either when 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 functions.

2. Cable Length Detect
Less power is required to send data over shorter cable lengths. A TRENDnet GREENnet switch automatically detects the length of the cable that connects the switch to the given networked device and adjusts the power supply accordingly. This technology functions automatically and requires no management.

GREENnet 10/100Mbps Switch Ports
· 1-20 meters (1 - 65 ft) = Reduced Power
· 21+ meters (66+ ft) = Full Power

GREENnet Gigabit Switch Ports
· 1-10 meters (1- 32 ft) = Significantly Reduced Power
· 11-60 meters (32 - 197 ft) = Reduced Power
· 61+ meters (198+ ft) = Full Power

3. Standby Mode
A TRENDnet GREENnet switch reduces the amount of power consumed by operating in standby mode when it is not being used.
