Configuring Green Ethernet

Green Ethernet, also known as Energy Efficient Ethernet, is an effort to make networking equipment
environmentally friendly, specifically by reducing power usage of Ethernet connections. The following
methods are supported by the device:
• Energy-Detect — Auto-detection of inactivity on a port, and subsequent turning down of transmit
power. It may take about 1 second for the cable to power-up when it becomes active again.
• Short-Reach — Reduction of power over Ethernet cables shorter than 40m. The cable length is
detected automatically with an accuracy of +/- 10m.
These methods are relevant for copper cables only, and are incompatible with fiber cable or when the link
is set to auto-selection of copper/fiber.
The short-reach method is only for a link established at 1 Gigabyte, and is not compatible with Fast
Ethernet.
