Operation Manual – PoEH3C S7500 Series Ethernet Switches Chapter 1 PoE Configuration1-7Note:z The refresh update mode is to upgrade the valid software in the PSE throughrefreshing the software, while the full update mode is to delete the invalid softwarein PSE completely and then reload the software.z Generally, the refresh update mode is used to upgrade the PSE processingsoftware.z When the PSE processing software is damaged (that is, no PoE commands can besuccessfully executed), you can use the full update mode to upgrade and restorethe software.z When the upgrading procedure in refresh update mode is interrupted for someunexpected reason (such as power-off) or some errors occur, if the upgrade in fullmode fails after restart, you must upgrade in full mode after power-off and restart ofthe device. In this way, the upgrade procedure succeeds.1.3 Displaying PoE ConfigurationTo do… Use the command… RemarksDisplay the PoE status of aspecific port or all ports of theswitchdisplay poe interface{ interface-type interface-number |all }Display the PoE powerinformation of a specific port orall ports of the switchdisplay poe interface power{ interface-type interface-number |all }Display the PSE parameters display poe powersupplyDisplay the power supply statusof each board and the power thatthe board suppliesdisplay poe pseAvailable inany view1.4 PoE Configuration ExampleI.
