To configure the Green Ethernet Configuration features:
1. Select System Management Green Ethernet Green Ethernet Configuration.
The following screen displays:
2. Enable or disable the Auto Power Down Mode.
• Enable. When the port link is down, the PHY automatically goes down for a short
period and then wakes up to check link pulses. This allows the port to continue to
perform autonegotiation while consuming less power when no link partner is present.
• Disable. Provide full power to the PHY even if no link partner is present.
3. Enable or disable the Short Cable Mode.
• Enable. When the port link is up at 1-Gbps speed, the cable length test is performed.
If the cable length is less than 10 meters, PHYs are put into the low-power mode so
only enough power is used to support a short cable.
• Disable. Provide full power to the PHY regardless of cable length.
4. Enable or disable the EEE Mode.
• Enable. Enter a low-power mode and disable some functionality for power savings
when the link is lightly loaded.
• Disable. Provide full power to the PHY always.
5. Click APPLY to apply the change to the system.
Configuration changes take effect immediately.
