1-6Configuring PoE Over-Temperature Protection on the SwitchWhen the internal temperature of the switch exceeds the PoE protection temperature, the switchdisables the PoE feature on all ports for self-protection; When the internal temperature of the switchdrops below the PoE restoration temperature, the switch restores the PoE settings on all ports. Table1-2shows the PoE protection and restoration temperatures of switches.Table 1-9 Configure PoE over-temperature protection on the switchOperation Command DescriptionEnter system view system-view —Enable PoE over-temperatureprotection on the switchpoe temperature-protectionenableOptionalEnabled by default.Upgrading the PSE Processing Software OnlineThe online upgrading of PSE processing software can update the processing software or repair thesoftware if it is damaged. Before performing the following configuration, download the PSE processingsoftware to the Flash of the switch.Table 1-10 Upgrade PSE processing software onlineOperation Command DescriptionEnter system view system-view —Upgrade the PSE processingsoftware onlinepoe update { refresh | full }filenameRequiredThe specified PSE processingsoftware is a file with theextension .s19.z In the case that the PSE processing software is damaged (that is, no PoE command can beexecuted successfully), use the full update mode to upgrade and thus restore the software.z The refresh update mode is to upgrade the original processing software in the PSE throughrefreshing the software, while the full update mode is to delete the original processing software inPSE completely and then reload the software.z Generally, the refresh update mode is used to upgrade the PSE processing software.z When the online upgrading procedure is interrupted for some unexpected reason (for example, thedevice restarts due to some errors), if the upgrade in full mode fails after restart, you must upgradein full mode after power-off and restart of the device, and then restart the device manually. In thisway, the former PoE configuration is restored.Displaying PoE ConfigurationAfter the above configuration, execute the display command in any view to see the operation of thePoE feature and verify the effect of the configuration.
