Green Ethernet
Link detection
Compliant with IEEE802.3az Energy Efficient Ethernet Task Force. Automatically turns off power on Gigabit Ethernet RJ-45 port when detecting link down or idle of client. Active mode is resumed without loss of any packets when the switch detects the link up
Cable length detection
Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter.
