It automatically adjusts power consumption according to the link status and cable length to limit the carbon footprint of your network.- Power down Idle PortsWhen a computer or network equipment is off the corresponding port of a traditional switch will continue to consume considerable amounts of power. The TL-SG105 can automatically detect the link status of each port and reduce the power consumption of ports that are idle resulting in up to an 65% reduction in power use.- Power Budget According to Cable LengthIdeally shorter cable would use less power because of less power degradation over their length; this is not the case with most devices as they will use the same amount of power across the cable regardless of the length.
