STEP 3 Click Apply to set the global settings
The following fields are displayed:
•
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 in watt hours This value is updated each time there
is an event that affects power saving
For each port the following fields are described:
Port—The port number
•
Short Reach Mode—State of the port regarding Short Reach mode
•
Short Reach Status—Status of the port regarding Short Reach mode is
•
either Enabled or Disabled
Short Reach Reason—If Short-Reach mode is not operational, displays

Cable Length—Displays VCT-returned cable length in meters
•
EEE Mode—State of the port regarding the EEE feature
•
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 window 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
EEE Status—State of EEE on the device (enabled or disabled)

Overview
A 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
