LABEL DESCRIPTION
PoE Mode This field displays the power management mode used by the Switch, whether it is in
Classification or Consumption mode.
Total Power (W) This field displays the total power the Switch can provide to the connected PoE-enabled
devices on the PoE ports.
PoE Usage (%) This field displays the amount of power currently being supplied to connected PoE devices (PDs)
as a percentage of the total PoE power the Switch can supply.
When PoE usage reaches 100%, the Switch will shut down PDs one-by-one according to the PD

Consuming
Power (W) This field displays the amount of power the Switch is currently supplying to the connected PoE-
enabled devices.
Allocated Power

PoE after negotiating with the connected PoE devices. It shows
NA when the Switch is in
consumption mode.
Consuming Power (W) can be less than or equal but not more than the Allocated Power (W) .
Remaining
Power (W) This field displays the amount of power the Switch can still provide for PoE.
Note: The Switch must have at least 16 W of remaining power in order to supply
power to a PoE device, even if the PoE device needs less than 16 W.
Port This is the port index number.
State This field shows which ports can receive power from the Switch. You can set this in Section 60.3
