The specified PSE processing software is a
file with the extension .s19.
z In the case that the PSE processing software is damaged (that is, no PoE command can be
executed 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 through
refreshing the software, while the full update mode is to delete the original processing software in
PSE 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, the
device restarts due to some errors), if the upgrade in full mode fails after restart, you must upgrade
in full mode after power-off and restart of the device, and then restart the device manually. In this
way, the former PoE configuration is restored.
