LABEL DESCRIPTION
PoE Mode Select the power management mode you want the Switch to use.
• Classification – Select this if you want the Switch to reserve the maximum power for each PD
according to the PD's power class and priority level. If the total power supply runs out, PDs
with lower priority do not get power to function. In this mode, the maximum power is reserved
based on what you configure in Max Power or the standard power limit for each class.
• Consumption – Select this if you want the Switch to supply the actual power that the PD
needs. The Switch also allocates power based on a port's Max Power and the PD's power
class and priority level. The Switch puts a limit on the maximum amount of power the PD can
request and use. In this mode, the default maximum power that can be delivered to the PD is
33 W (IEEE 802.3at Class 4) or 22 W (IEEE 802.3af Classes 0 to 3).
Continuous Select Active to guarantee continuous power supply to the connected PDs while the Switch is
PoE restarting after a warm reboot. The Switch will NOT perform a power cycle on the connected PDs.
If you do a cold reboot, the Switch also restarts the connected PDs.
PoE Usage Enter a number ranging from 1 to 99 to set the threshold. The Switch will generate a trap and/or
Threshold (%) log when the actual PoE usage is higher than the specified threshold.
Port This is the port index number.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Changes in this row are copied to all the ports as soon as you make them.
Active Select this to provide power to a PD connected to the port.
If left unchecked, the PD connected to the port cannot receive power from the Switch.
Priority When the total power requested by the PDs exceeds the total PoE power budget on the Switch,
you can set the PD priority to allow the Switch to provide power to ports with higher priority.
Select Critical to give the highest PD priority on the port.
Select High to set the Switch to assign the remaining power to the port after all critical priority
ports are served.
Select Low to set the Switch to assign the remaining power to the port after all critical and high
priority ports are served.
