Description
Select the unit you wish to configure. Tick the All check box to select all units.
Sets the limit of power to be used from the Switch's power source to PoE ports. The user
may configure a Power Limit between 1 and 370W for the DGS-3120-24PC and DGS-3120-
48PC. The default setting is 370W.
The PoE controller uses either Deny Next Port or Deny Low Priority Port to offset the power
limit being exceeded and keeps the Switch's power at a usable level. Use the drop down
menu to select a Power Disconnect Method. The default Power Disconnect Method is
Deny Next Port. Both Power Disconnection Methods are described below:
Deny Next Port – After the power limit has been exceeded, the next port attempting to
power up is denied, regardless of its priority. If Power Disconnection Method is set to Deny
Next Port, the system cannot utilize out of its maximum power capacity. The maximum
unused watt is 19W.
Deny Low Priority Port – After the power limit has been exceeded, the next port attempting
to power up causes the port with the lowest priority to shut down so as to allow the high-
priority and critical priority ports to power up.
Use the drop-down menu to enable or disable detecting legacy PDs signal.
