Description
Select a range of ports from the drop-down menus to be enabled or disabled for PoE.
Use the drop-down menu to enable or disable ports for PoE.
Select a range of the time to the port set as POE. If Time Range is configured, the power
can only be supplied during the specified period of time.
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 order 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.
This function is used to configure the per-port power limit. If a port exceeds its power
limit, it will shut down.
