PoE Configuration 341Enabling the PoEFeature on a Portc CAUTION:■ By default, the PoE function on a port is enabled by the default configurationfile 3comoscfg-xxport.def when the device is delivered.■ If you delete the default configuration file without specifying another one, thePoE function on a port will be disabled after you restart the device.Setting the MaximumOutput Power on a PortThe maximum power that can be supplied by each Ethernet electrical port of aPoE-enabled Switch 4210 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 rangeof 1,000 to 15,400 mW and in the granularity of 100 mW.Setting PoEManagement Mode andPoE Priority of a PortWhen a switch is close to its full load in supplying power, you can adjust thepower supply of the switch through the cooperation of the PoE managementmode and the port PoE priority settings. The Switch 4210 supports two PoEmanagement modes, auto and manual. The auto mode is adopted by default.■ auto: When the switch is close to its full load in supplying power, it will firstsupply power to the PDs that are connected to the ports with critical priority,and then supply power to the PDs that are connected to the ports with high“Configuring the PD Compatibility Detection Function” Optional“Configuring PoE Over-Temperature Protection on theSwitch”Optional“Upgrading the PSE Processing Software Online” Optional“Upgrading the PSE Processing Software Online” Optional“Displaying PoE Configuration” OptionalConfiguring PoE Over-Temperature Protection on the Switch OptionalUpgrading the PSE Processing Software Online OptionalDisplaying PoE Configuration OptionalTable 260 PoE configuration tasksTask RemarksTable 261 Enable the PoE feature on a portOperation Command DescriptionEnter system view system-view -Enter Ethernet port view interface interface-typeinterface-number-Enable the PoE feature on aportpoe enable RequiredTable 262 Set the maximum output power on a portOperation Command DescriptionEnter system view system-view -Enter Ethernet port view interface interface-typeinterface-number-Set the maximum outputpower on the portpoe max-power max-power Required15,400 mW by default.
