It can also supply power to some PDs that donot support the 802.3af standard.z It can deliver data and current simultaneously through data wires (1,2,3,6) of category-3/5 twistedpairs.z The PSE processing software on the device can be upgraded online.z The device provides statistics about power supplying on each port and the whole equipment, whichyou can query through the display command.z The device provides two modes (auto and manual) to manage the power feeding to ports in thecase of PSE power overload.z The device provides over-temperature protection mechanism. When the internal temperature ofthe device exceeds the PoE protection temperature, the device disables the PoE feature on allports for self-protection.z The device supports the PoE profile feature, that is, different PoE policies can be set for differentuser groups. These PoE policies are each saved in the corresponding PoE profile and applied toports of the user groups.z When you use the PoE-enabled device to supply power, the PDs need no external power supply.z If a remote PD has an external power supply, the PoE-enabled device and the external powersupply will backup each other for the PD.z Only the Ethernet electrical ports of the PoE-enabled device support the PoE feature.PoE ConfigurationPoE Configuration Task ListComplete the following tasks to configure PoE:
