Configuring a PSE 1013
Configuring a PSE Follow these steps to configure a PSE:
n
■ When the remaining power of the PoE system is lower than the maximum
power of the PSE, PoE is disabled for the PSE.
■ 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 so as to guarantee the
power supply to these PoE interfaces.
■ The relation between the ID and slot number of a PSE is: PSE ID = SlotNo x 3 +
1.
Configuring a PoE
Interface
You can configure a PoE interface in either of the following two ways:
■ Adopt the command line.
■ Configure a PoE configuration file and apply the file to the specified PoE
interface(s).
Usually, you can adopt the command line to configure a single PoE interface, and
adopt a PoE configuration file to configure multiple PoE interfaces at the same
time.
c
CAUTION: You can adopt either mode to configure, modify, or delete a PoE
configuration parameter under the same PoE interface.
For the Switch 8800s, PoE interfaces can only use signal cables to supply power.
