Configuring the PoE Monitoring Function
The PoE monitoring function involves monitoring of PoE power, PSE and PD.
z Monitoring PoE power means monitoring the voltage of the PoE power.
z When the current power utilization of the PSE is above or below the alarm threshold for the first
time, the system will send a Trap message.
z When the PSE starts or stops supplying power to a PD, the system will send a Trap message, too.

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.
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.
