Parameter Description
Unit
Choose the switch in the switch stack for which to configure the PoE settings.
From Port/To Port
Select a range of ports from the drop-down menus to be enabled or disabled for PoE.
State
Use the drop-down menu to enable or disable ports for PoE.
Priority
Use the drop-down menu to select the priority of the PoE ports. Port priority determines the
priority which the system attempts to supply the power to the ports. There are three levels of
priority that can be selected, Critical, High, and Low. When multiple ports happen to have the
same level of priority, the port ID will be used to determine the priority. The lower port ID has
higher priority. The setting of priority will affect the ordering of supplying power. Whether the
disconnect method is set to deny low priority port, the priority of each port will be used by the
system to manage the supply of power to ports.
Power Limit
This function is used to configure the per-port power limit. If a port exceeds its power limit, it
will shut down.
Based on 802.3af/802.3at, there are different PD classes and power consumption ranges;
