1-23) PI: An Ethernet interface with the PoE capability is called PoE interface. Currently, a PoE interfacecan be an FE or GE interface.4) PD: A PD is a device accepting power from the PSE, including IP phones, wireless APs, chargersof portable devices, POS, and web cameras.The PD that is being powered by the PSE can be connected to another power supply unit forredundancy power backup.Figure 1-1 PoE system diagramProtocol SpecificationThe protocol specification related to PoE is IEEE 802.3af.PoE Configuration Task ListYou can configure a PoE interface in either of the following two ways:z Through command lines.z Through configuring the PoE profile and applying the PoE profile to the PoE interface.When configuring a single PoE interface, you can use command lines; when you configure PoEinterfaces in batches, you can use the PoE profile. For a PoE configuration parameter of a PoEinterface, you can only select one mode (including modification and removal of a PoE interface).Complete these tasks to configure PoE:Task RemarksEnabling PoE Enabling PoE for a PoE Interface RequiredEnabling the PSE to Detect Nonstandard PDs OptionalDetecting PDs Configuring a PD Disconnection DetectionMode OptionalConfiguring the PoEPowerConfiguring the Maximum PoE InterfacePower OptionalConfiguring PoE PowerManagementConfiguring PoE Interface PowerManagement Optionalonfiguring PSE Power Monitoring OptionalConfiguring the PoEMonitoring Function Monitoring PDOptionalThe deviceautomaticallymonitors PDs whensupplying power to
