What Green Ethernet Features available in CBS 250 series switches?

Green Ethernet refers to a set of features aimed at being environmentally friendly and reducing device power consumption. Unlike EEE, which only enables energy-detect on Gigabit ports, Green Ethernet enables it on all devices.

Green Ethernet can lower overall power usage through the following methods:

1. Energy-Detect Mode: When a link is inactive, the port enters an inactive mode, conserving power while maintaining the port’s administrative status as active. Transitioning back to full operational mode is quick and seamless, with no frame loss. This mode is available on both GE and FE ports but is disabled by default.
2. short-Reach Mode: This feature saves power on shorter cable lengths. After analyzing the cable length, power usage is adjusted accordingly. For cables shorter than 30 meters on TenGigabit ports and 50 meters on other ports, the device uses less power to transmit frames, thus conserving energy. This mode is only supported on RJ45 ports and does not apply to Combo ports. It is also disabled by default.
