xStack® DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Figure 2 - 126 PoE System Settings window The following parameters can be configured: Parameter Description Unit Choose the switch in the switch stack for which to configure the PoE settings. Users should note that not all switches in the xStack® DGS-3400 Series support PoE yet, when they are configured in a stack, the Primary Master switch will display the PoE settings to be configured for the stack, whether or not the Switch is a PoE supported device. However, only PoE supported switches have the PoE capability in the switch stack. Power Limit (37370W) 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 37 and 370W for the DGS-3426P. The default setting is 370W. Disconnect Method The PoE controller uses either Deny next port or Deny low priority port to offset the power limit being exceeded and keep the Switch's power at a usable level. Use the drop-down menu to select a Disconnect Method. The default for the 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. 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 to allow the high-priority and critical priority ports to power up. Management Mode Use the drop-down menu to select the management mode. Power Limit - Specifies that the previously set power limit will be implemented. Auto - Specifies that system will automatically determine the management mode. Legacy PD Use the drop-down menu to enable or disable detecting legacy PDs signal. Click Apply to implement the changes. 104
