H3C s3600 series Command Manual page 882

Use the full mode only when the refresh mode fails. In normal cases, use the refresh mode.
When the PSE processing software is damaged (that is, all the PoE commands cannot be
successfully executed), you can use the full mode to update and restore the software.
When the online upgrading procedure is interrupted for some unexpected reason, for example, the
device is restarted 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.
