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.
Consuming
Power (W)
This field displays the amount of power the Switch is currently supplying to the connected PoE-
enabled devices.
Allocated Power
(W)
This field displays the total amount of power the Switch has reserved for PoE after negotiating
with the connected PoE device(s).
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 16W.
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 8.8.2
on page 74.
• Disable - The PD connected to this port cannot get power supply.
• Enable - The PD connected to this port can receive power.
Class This shows the power classification of the PD.
This is a number from 0 to 4, where each value represents a range of power (W) and power
current (mA) that the PD requires to function. The ranges are as follows.
• Class 0 - Default, 0.44 to 12.94
• Class 1 - Optional, 0.44 to 3.84
• Class 2 - Optional, 3.84 to 6.49
• Class 3 - Optional, 6.49 to 12.95
• Class 4 - Reserved (PSEs classify as Class 0) in a Switch that supports IEEE 802.3af only.
Optional, 12.95 to 25.50 in a Switch that supports IEEE 802.3at.
