Operation Manual – PoE-PoE ProfileH3C S5600 Series Ethernet Switches Chapter 1 PoE Configuration1-4Caution:z By default, the PoE function on a port is enabled by the default configuration file(config.def) when the device is delivered.z If you delete the default configuration file without specifying another one, the PoEfunction on a port will be disabled after you restart the device.1.2.3 Setting the Maximum Output Power on a PortThe maximum power that can be supplied by each Ethernet electrical port of aPoE-enabled S5600 switch to its PD is 15,400 mW. In practice, you can set themaximum power on a port depending on the actual power of the PD, in the range of1,000 to 15,400 mW and in the granularity of 100 mW.Follow these steps to set the maximum output power on a port:To do… Use the command… RemarksEnter system view system-view —Enter Ethernet port view interface interface-typeinterface-number —Set the maximum outputpower on the portpoe max-powermax-powerRequired15,400 mW by default.1.2.4 Setting PoE Management Mode and PoE Priority of a PortWhen a switch is close to its full load in supplying power, you can adjust the powersupply of the switch through the cooperation of the PoE management mode and theport PoE priority settings. S5600 series switches support two PoE management modes,auto and manual. The auto mode is adopted by default.z auto: When the switch is close to its full load in supplying power, it will first supplypower to the PDs that are connected to the ports with critical priority, and thensupply power to the PDs that are connected to the ports with high priority. Forexample: Port A has the priority of critical. When the switch PoE is close to its fullload and a new PD is now added to port A, the switch will power down the PDconnected to the port with the lowest priority and turn to supply power to this newPD. If more than one port has the same lowest priority, the switch will power downthe PD connected to the port with larger port number.z manual: When the switch is close to its full load in supplying power, it will notmake change to its original power supply status based on its priority when a newPD is added. For example: Port A has the priority critical. When the switch PoE is
