thus impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the
port is powered up again. Because there are some overhead in turning the port down and up,
more power can be saved if the traffic can be buffered up until a large burst of traffic can be
transmitted. Buffering traffic will give some latency in the traffic.
Web Interface
To configure a Port Power Saving Configuration in the web interface:
1. Click Configuration, Green Ethernet
2. Evoke to enable or disable the ActiPHY, PerfectReach, EEE and EEE Urgent Queues .
3. Click Apply.
Figure 2-2.1: The Port Power Saving Configuration
Parameter description:
Optimize EEE for
The switch can be set to optimize EEE for either best power saving or least traffic
latency.
Port:
The switch port number of the logical port.
ActiPHY :
Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is
power up for short moment in order to determine if cable is inserted.
