To configure a single PoE interface, configure it at the CLI. To configure several PoE interfaces in batches,
use the PoE profile. For a PoE configuration parameter of a PoE interface, you can select only one mode
(including modification and removal of a PoE interface).
Before configuring PoE, make sure the PoE power supply and PSE are operating properly. Otherwise,
either you cannot configure PoE or the PoE configuration does not take effect.
If the PoE power supply is turned off while a device is starting up, the PoE configuration in the PoE profile
might become invalid.
Complete these tasks to configure PoE:
Task Remarks
Enabling PoE:

• Configuring the maximum PSE power Optional.
• Configuring the maximum PoE interface power Optional.
Configuring PoE power management:
• Configuring PSE power management Optional.
• Configuring PoE interface power management Optional.
Configuring the PoE monitoring function:
• Configuring PSE power monitoring Optional.
Optional.
The device automatically
monitors PDs when
supplying power to them,
so no configuration is
required.
