Power Efficiency

• Energy Detect Automatically turns off power on Gigabit Ethernet RJ-45 port when the switch detects a link down Active mode is resumed without loss of any packets when the switch detects the link is back up
• Cable length detection Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter than 10 m.

Discovery
