Selling Point6 - Green Ethernet for Power Saving Achieving a total power consumption less than competing products. Cutting power consumption when the network cable is disconnected from LAN. Intranet Power Consumption Intranet The f/w v1.10 implements a special function to reduce power consumption – Green Ethernet. DAP-1522 will automatic detect the cable length and then select different power mode for best performance with minimums power consumption. There are three power modes that reflect to a certain range of cable length (shorter than 20m, length is in 20m ~ 60m, longer than 60m) when Green Feature is enabled. The Green Feature could dynamic estimate connection cable length and turn on different power mode with cable estimate result. It could work on best performance with minimums power consumption in various length cables. The channel estimate is implemented by DSP technology in the physical layer transceivers. It also implements power saving mode on a per-port basis. A port automatically enters power saving mode 10 seconds after the cable is disconnected from it when power saving mode is enabled. Once a port enters power saving mode, it transmits normal link pulses only on its TXOP/TXON pins and continues to monitor the RXIP/RXIN pins to detect incoming signals, which might be the 100Base-TX MLT-3 idle pattern, 10Base-T link pulses, or Auto-Negotiation’s FLP (Fast Link Pulse). After it detects any incoming signals, it wakes up from power saving mode and operates in normal mode according to the result of the connection. Normal AP Normal AP DAP-1522
