PoE
PoE
The PoE/Cable page displays detailed information about the setup and status of power over Ethernet for each port and for the PoE
device as a whole. This data will be useful for setting, enabling, disabling, and managing the switch's power budget.
The PoE page contains two panes:
•
PoE Status
•
PoE Administration
PoE Status
This pane displays the power over Ethernet status parameters.
Port # - The appliance port number to which the selected device is connected.
Link State - Up indicates that a device is connected to this port; Down indicates that no device is connected.
PoE Mode/PoE Class - Type of device the switch has detected. This is not configurable, rather the values assigned by the switch
based on its interaction and power draw of the attached device.
•
PoE Mode values will be either AT or AF referring to the IEEE 802.3at or IEEE 802.3af standards.
•
PoE Class values range from 0 to 4 and correspond to the following properties as defined in the IEEE standard
and as shown in the table below:

Power Draw - The average number of watts the attached device is consuming.
Power Limit - This displays a default limit based on the PoE mode and class.
PoE Enabled/Disabled - Allows you to view and change the PoE Enabled/Disabled status to turn the PoE to the device on or off for
devices. Devices requiring PoE will be turned off when disabled and the link state will change to Down.
PoE Administration
This pane summarizes the switch's current total power consumption and power availability information. It also provides a general PoE
control.
(Watts Scale) and Total PoE Usage - Shows the amount of power (in watts) being drawn by all devices currently attached to the
switch along with the total power consumed (in watts and percentages) by all attached devices. This is helpful when installing
devices and verifying your power budget.
PoE Port Active - Shows the number of ports that are currently enabled for data providing power over Ethernet.
Master PoE (Enable All / Disable All) - Allows you to enable or disable PoE for all the ports in one command. You can toggle all
PoE on or off for all ports.
