xStack® DGS-3120 Series Managed Switch Web UI Reference Guide Figure 2-8 PoE System Settings window The following parameters can be configured: Parameter Description Unit Select the unit you wish to configure. Tick the All check box to select all units. Power Limit (37740) Power Disconnect Method Legacy PD 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 37W and 740W for the DGS-3120-24PC and DGS-3120-48PC. The default setting is 740W. 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. Click Apply to implement changes made.
