ONFIGURATION
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:

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.

CAUTION: If you adjust the PD disconnection detection mode when the device is
running, the connected PDs will be powered off. Therefore, be cautious to do so!
There are standard PDs and nonstandard PDs. Usually, the PSE can detect only
standard PDs and supply power to them. The PSE can detect nonstandard PDs and
supply power to them only after the PSE is enabled to detect nonstandard PDs.
Follow these steps to enable the PSE to detect nonstandard PDs:
