TP-Link 24-port gigabit desktop/rockmount switch TL-SG1024D

Power down Idle Ports
When a computer or network equipment is off, the corresponding port of a traditional switch will continue to consume considerable amounts of power. The TL-SG1024D can automatically detect the link status of each port and reduce the power consumption of ports that are idle.


Power Budget According to Cable Length
Ideally, shorter cables 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 whether it is 10 or 50 meters (32.8 or 164.0 feet )in length. The TL-SG1024D analyzes the length of the Ethernet cable connected and adjusts the power usage accordingly, rather than keeping the power consumption in a conventional solution.
