1-7Upgrading the PSE Processing Software of Fabric Switches OnlineYou can update or repair the damaged PSE processing software through upgrading it.By executing the following command on any device in the fabric, you can upgrade the PSE processingsoftware of all devices in the fabric by using the specified PSE processing software. For details of fabric,see the IRF Fabric part of this manual.Follow these steps to upgrade the PSE processing software online:To do… Use the command… RemarksUpgrade the PSE processingsoftware of the fabric switch onlineupdate fabric { file-url |device-name file-url } OptionalDisplaying PoE ConfigurationTo do… Use the command… RemarksDisplay the PoE status of a specific port or allports of the switchdisplay poe interface [ interface-typeinterface-number ]Display the PoE power information of a specificport or all ports of the switchdisplay poe interface power[ interface-type interface-number ]Display the PSE parameters display poe powersupplyDisplay the status (enabled/disabled) of thePoE over-temperature protection feature onthe switchdisplay poe temperature-protectionAvailable in anyviewPoE Configuration ExamplePoE Configuration ExampleNetwork requirementsSwitch A is an S5600 series Ethernet switch supporting PoE, Switch B can be PoE powered.z The GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 ports of Switch A are connected to Switch Band an AP respectively; the GigabitEthernet 1/0/8 port is intended to be connected with animportant AP.z The PSE processing software of Switch A is first upgraded online. The remotely accessed PDs arepowered by Switch A.z The power consumption of the accessed AP is 2,500 mW, and the maximum power consumptionof Switch B is 12,000 mW.z It is required to guarantee the power feeding to the PDs connected to the GigabitEthernet 1/0/8 porteven when Switch A is under full load.
