Note
—If Short Reach is enabled, EEE must be disabled.
•
802.3 Energy Efficient Ethernet (EEE)—Select to globally enable EEE.
2. Click Apply to set the global settings.
•
Power Savings—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—The amount of energy saved from the last device
reboot in watt hours. This value is updated each time there is an event that affects
power saving.
3. Select a port and click Edit.
•
Select Your Port
o
Port—Select a port from the drop-down menu.
•
Port Settings
o
Energy Detect Mode—Select to enable.
o
Short Reach Mode—Select to enable.
o
802.3 EEE Mode—Select to enable.
o
EEE LLDP Mode—Select to enable.
•
EEE Status—Whether EEE is currently operating on the local port. This is a
function of whether it has been enabled (Administrative Status), whether it has
been enabled on the local port and whether it is operational on the local port.
Note
—The Green Ethernet Table displays the Short Reach, Energy Detect and
EEE settings for each port; however, they are not enabled on any port unless they
are also enabled globally.
PoE
A Power over Ethernet (PoE) device is PSE (Power Sourcing Equipment) that delivers electrical
power to connected PD (Powered Devices) over existing copper cables without interfering with
the network traffic, updating the physical network or modifying the network infrastructure. The
PoE feature is only available on PoE-based devices.
