Configuring the PoE power
Configuring the maximum PSE power
The maximum PSE power is the sum of power that the PDs connected to the PSE can get.
To avoid PSE power interruption due to PoE power overload, make sure the sum of power of all PSEs is
less than the maximum PoE power.
The maximum power of the PSE must be greater than or equal to the total maximum power of all critical
PoE interfaces on the PSE to guarantee these PoE interfaces of power.
To configure the maximum PSE power:
Step Command Remarks
416. Enter system view. system-view N/A
Default maximum power of the PSE:
417. Configure the maximum
power for the PSE.

• MIM/FIC 16FSW—247 W.
• MIM/FIC 24FSW—370 W.
Configuring the maximum PoE interface power
The maximum PoE interface power is the maximum power that the PoE interface can provide to the
connected PD. If the PD requires more power than the maximum PoE interface power, the PoE interface
does not supply power to the PD.
To configure the maximum PSE power:
Step Command Remarks

Optional. 420. Configure the maximum
power for the PoE interface.

The default is 15400 milliwatts.
Configuring PoE power management
PoE power management involves PSE power management and PoE interface power management.
Configuring PSE power management
If the maximum PoE power is lower than the sum of the maximum power that all PSEs require, PSE power
management is applied to decide whether the PSE can enable PoE, whether to supply power to a specific
PSE, and the power-allocation method. If the maximum PoE power of the device is higher than the sum
of the maximum power that all PSEs require, it is unnecessary to enable PSE power management.
