Manage the built-in switch
PoE tab
In the PoE tab, you find formation about the setup and status of power over Ethernet (PoE) for each port and for the PoE enabled
devices as a whole. This data is useful for setting, enabling, disabling, and managing the switch’s power budget.
Pane Function Description
Port status 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 Type of device the switch has detected. This is not configurable, the
values are assigned by the switch based on its interaction and power
draw of the connected device.
PoE mode values are either AT or AF. These values refer to the IEEE
802.3at or IEEE 802.3af standards.
PoE class Type of device the switch has detected. This is not configurable, the
values are assigned by the switch based on its interaction and power
draw of the connected device.
PoE Class values range from 0 to 4 and correspond to the following
properties as defined in the IEEE standard:

High power
Power draw The average number of watts the connected device is consuming.
Power limit Displays a default limit based on the PoE mode and class.
PoE enabled Allows you to view and change the PoE enabled or 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 Watts scale
The amount of power (in watts) drawn by all devices currently connected
to the switch.
Total PoE usage
The total power consumed (in watts and percentages) by all connected
devices.
This information is helpful when installing devices and verifying your
power budget.
