344 CHAPTER 31: POE CONFIGURATION
n
■ 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.
■ 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.
■ Generally, the refresh update mode is used to upgrade the PSE processing
software.
■ 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.
