1.6 Upgrading PSE Processing Software Online

You can upgrade the PSE processing software online in either of the following two
modes:
refresh mode
This mode enables you to update the PSE processing software without deleting it.
Normally, you can upgrade the PSE processing software in the refresh mode through
the command line.
full mode
This mode deletes the PSE processing software and reloads it. When the PSE
processing software is damaged (in this case, you can execute none of PoE commands
successfully), you can upgrade the PSE software processing software in full mode to
restore the PSE function.
Online PSE processing software upgrade may be unexpectedly interrupted (for
example, an error results in device reboot). If you fail to upgrade the PSE processing
software in full mode after reboot, you can power off the device and restart it before
upgrading it again. After upgrade, restart the device manually to make the original PoE
configurations take effect.
Follow these steps to upgrade the PSE processing software online:

1.7 Configuring a PD Disconnection Detection Mode

To detect the PD connection with PSE, PoE provides two detection modes: AC
detection and DC detection. The AC detection mode is energy saving relative to the DC
detection mode.
Follow these steps to configure a PD disconnection detection mode:
