1.8 Upgrading PSE Processing Software Online
You can upgrade the PSE processing software online in either of the following two
modes:
z 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.
z 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.

1.9 Enabling the PSE to Detect Nonstandard PDs
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.
