Configuring a Power Alarm Threshold for the PSE 1197
interface from critical to a lower level, the PDs connecting to other PoE interfaces
will have an opportunity of being powered.
Configuration prerequisites
Enable PoE for PoE interfaces.
Configuration procedure
Follow these steps to configure PD power management:
Configuring a Power
Alarm Threshold for
the PSE
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.
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.
