1.3 Configuring the PoE Power
The maximum PoE power refers to the maximum power that the device can provide for
all PSEs. To avoid a power failure to the PSE owing to overload, the sum of the power
consumption of all PSEs should not exceed the maximum power of the device.
Follow these steps to configure the PoE power:

max-power [ pse pse-id ]
Optional
37 watts by default.
 Note:
z When the remaining power of the PoE system is lower than the maximum power of
the PSE, PoE is disabled for the PSE.
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.
1.5 Configuring the PoE Interface
You can configure a PoE interface in either of the following two ways:
z Adopting the command line.
z Configuring a PoE configuration file and applying the file to the specified PoE
interface(s).
