Description
Use the
poe upgrade
command to upgrade the processing software in the PSE online.
Note:
z
The
full
mode is used only when you cannot use the
refresh
mode.
z
When the PSE processing software is damaged (that is, no PoE commands can be
successfully executed), you can use the
full
mode to update and restore the
software.
z
When the upgrade procedure is interrupted for some unexpected reasons (such as
failure which causes restart), if the update in the
full
mode fails after restart, you
must upgrade the software in the
full
mode after power-off and restart of the device,
and then restart the device manually. In this way, the former PoE configuration can
be restored.
