To do...
Enable PoE for the PSE
Configure the
maximum power for the
PSE
n
pse-id indicates number of the slot where a PoE interface locates.
■
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.
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.
The PSE applies power to a PoE interface in the following two modes:
For a device with only signal cables, power is supplied over signal cables.
■
For a device with spare cables and signal cables, power can be supplied over
■
spare cables or signal cables.
n
Some PSE does not support power over spare cables.
To clearly identify the PD connected to a PoE interface, you can give a PD
description.
Follow these steps to configure a PoE interface through the command line:
To do...
Enter system view
Enter PoE interface view interface interface-type
Enable PoE
Use the command...
poe enable pse pse-id
poe max-power
max-power [ pse pse-id ]
Use the command...
system-view
interface-number
poe enable
