STEP 4 To see 802.3 EEE-related information on the local device, open the
Administration > Discovery LLDP >LLDP Local Information page, and view the
information in the 802.3 Energy Efficient Ethernet (EEE) block.
STEP 5 To display 802.3az EEE information on the remote device, open the Administration
> Discovery LLDP > LLDP Neighbor Information pages, and view the information in
the 802.3 Energy Efficient Ethernet (EEE) block.
Global Green Ethernet Properties
The Properties page displays and enables configuration of the Green Ethernet
mode for the device. It also displays the current power savings.
To enable Green Ethernet and EEE and view power savings:
STEP 1 Click Port Management > Green Ethernet > Properties.
STEP 2 Enter the values for the following fields:
• Energy Detect Mode—(Not available in SG500XG) Disabled by default.
Click the checkbox to enable.
• Short Reach—Globally enable or disable Short Reach mode if there are GE
ports on the device.
NOTE If Short Reach is enabled, EEE must be disabled.
• Port LEDs—Select to enable the port LEDs. When these are disabled, they
do not display link status, activity, etc.
• Power Savings—Displays the percentage of power saved by running
Green Ethernet and Short Reach. The power savings displayed is only
relevant to the power saved by Short Reach and Energy Detect modes. The
EEE power savings is dynamic by nature since it is based on port utilization
and is therefore not taken into consideration. The power saving calculation is
performed by comparing the maximum power consumption without power
savings to the current consumption.
• Cumulative Energy Saved—Displays the amount of energy saved from the
last device reboot. This value is updated each time there is an event that
affects power saving.
• 802.3 Energy Efficient Ethernet (EEE)— Globally enable or disable EEE
mode (only available if there are GE ports on the device).
