Green Ethernet Configuration - NETGEAR XS728T ProSAFE Software Administration Manual

• Auto Power Down Mode. Auto Power Down mode is always enabled. When the port link
is down, the physical layer (PHY) automatically shuts down for a short period and wakes
up to check link pulses. This mode reduces power consumption on the port when no link
partner is present.
• Short Cable Mode. Short Cable mode is always enabled. When the cable length is less
than a certain limit, the PHY goes into low-power mode.
• Energy Efficient Ethernet (EEE) Mode. EEE enables ports to enter a low-power mode
to reduce power consumption during periods of low link utilization. EEE is defined by
IEEE 802.3az. EEE enables both the send and receive sides of the link to disable some
functionality for power savings when the link is lightly loaded. By default this feature is
disabled globally and per interface.
From the Green Ethernet menu, you can access features described in the following sections:
•

Green Ethernet Configuration

• Green Ethernet Interface Configuration
• Green Ethernet Detail
• Green Ethernet Summary
Green Ethernet Configuration
To configure the Green Ethernet Configuration features:

1. Select System > Management > Green Ethernet > Green Ethernet Configuration.
2. The Auto Power Down Mode and Short Cable Mode features are enabled and cannot be
disabled.
3. 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.
4. Click Apply to apply the change to the system.
Configuration changes take effect immediately.
Green Ethernet Interface Configuration
Using the Green Ethernet Interface Configuration feature allows for proper port configuration
and the ability to enable or disable EEE Mode on specific ports.
To configure the Green Ethernet Interface feature:

1. Select System > Management > Green Ethernet > Green Ethernet Interface
Configuration.
2. Select the following interface settings for the physical port:
• Go To Interface. Enter a port identifier (appears in the Port column) and click Go.
The table entry corresponding to the specified port is selected.
