To put it simply, this product is incredibly energy efficient. It supports IEEE 802.3az (Energy Efficient Ethernet), and supports advanced link down power saving when the Ethernet cable is unplugged. Data integrity is guaranteed with support for crossover detection and auto-correction.

You can even turn on or awake your computer by a network message through Wake-on-LAN. The two LEDs separately indicate the power status and Ethernet connection.
