Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE) changes the priority value of port 22 of the OmniSwitch 6850 Series slot 8 to the highest priority level of critical. Now that the default value has been reconfigured, this port should be reserved for those PDs that are mission critical for network operations. Setting the Capacitor Detection Method By default, the PowerDsine capacitor detection method is disabled. To enable it, use the lanpower capacitor-detection command by entering lanpower capacitor-detection followed by the slot number of the switch and enable. For example, to enable the capacitor detection method on the switch with slot number 2, enter: -> lanpower capacitor-detection 2 enable To disable it, use the lanpower capacitor-detection command by entering lanpower capacitor-detection followed by the slot number and disable. For example, to disable the capacitor detection method on slot number 2, enter: -> lanpower capacitor-detection 2 disable Note. The capacitive detection method should only be enabled to support legacy IP phones. This feature is not compatible with IEEE specifications. Please contact your Alcatel-Lucent sales engineer or Customer Support representative to find out which Alcatel-Lucent IP phones models need capacitive detection enabled. page 5-8 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
