Power Limit: This function allows user to manually set the port power current limitation to be given to the PD.
To protect the DGS-1210 PoE series and the connected devices, the power limit function will disable the PoE
function of the port when the power is overloaded. Select from "Class 1", "Class 2", "Class 3", “Class 4”
and "Auto" for the power limit. "Auto" will negotiate and follow the classification from the PD power current
based on the 802.3at standard.
User Define: Check the box and input the power budget (from 1 to 30W) to manually assign an upper limit of
port power budget on designated port(s).
Legacy PD: Specifies to enable or disable detecting legacy PDs signal.
Click Apply to make the configurations take effects or click Refresh to redisplay the table.
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: This 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, this feature helps to extend the time interval to
500ms. If the PD is still not powering on, please contact technical support of
PD device.

The PD Alive function checks the PoE PD device all the time via ping action. Once the PD device stop
responding, DGS-1210 series will recycle the PoE port power or notify the network administrator.
