Configuring the Maximum PSE Power
The maximum PSE power is the sum of power that the PDs connected to the PSE can get.
Follow these steps to configure the maximum PSE power:
To do… Use the command… Remarks
Enter system view system-view —
Configure the maximum power
for the PSE
poe max-power max-power pse
pse-id
Optional
The default maximum power of
the PSE is 37.
z To avoid PSE power interruption due to PoE power overload, ensure that the sum of power
of all PSEs is less than the maximum PoE power.
z The maximum power of the PSE must be greater than or equal to the sum of maximum
power of all critical PoE interfaces on the PSE to guarantee the power supply to these PoE
interfaces.
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 power required by the PD is larger than the maximum PoE interface
power, the PoE interface will not supply power to the PD.

Configuring PoE Power Management
PoE power management involves PSE power management and PoE interface power
management.
