Description
Specify the PoE function of a port or ports.
Select enable or disable to configure PoE function for
designated port(s). Default is Enabled.
Configure the power supply priority as Low, High, or Critical
on designated port(s). Default is High.
This function allows you to manually set the port power current
limitation to be given to the PD. Select from Class 1, Class 2,
Class 3, Class 4, or Auto for the power limit. Auto will
negotiate and follow the classification from the PD power
current based on the 802.3at standard.
Check the box and input the power budget to manually assign
an upper limit of port power budget on designated port(s).
Table 4.5
NOTE: For the PoE Port Settings table, if the
classification was shown as "Legacy PD", it will
be classified to non-AF PD or Legacy PD.
NOTE: The Switch conforms to IEEE 802.3af
and 802.3at standards. The IEEE PoE standard
requires a switch to shut off power to a port if the
power draw is less than 10mA within a 400ms
time interval. To support some non-standard
devices that may take longer, you may enable
this feature to extend the time interval to 500ms.
If the PD is still not powering on, please contact
the vendor of your device for support.
