Before supplying power to a PD, the device performs a detection of the PD. It supplies power to the
PD only after the PD passes the detection. If the PD fails the detection but the power provided by
the device meets the PD specifications, you can execute this command to enable forced power
supply to the PD.
Examples
# Enable forced PoE power supply.

The PD might be damaged if the prowded by the device does not meet the PD power specifications.
Make sure you are fully aware of the impacts of this command when you use it in a live
network. Continue?[Y/N]: y
poe high-inrush enable
Use
poe high-inrush enable
to allow inrush currents drawn by PDs.
Use
undo poe high-inrush enable
to restore the default.
Syntax
poe high-inrush enable pse
pse-id
undo poe high-inrush enable pse pse-id
Default
Inrush currents drawn by PDs are not allowed.

Parameters
pse
pse-id
: Specifies a PSE by its ID.
Usage guidelines
CAUTION:
Inrush currents might damage the components on the device. Use this command with caution.
This command is available only for a PSE that has a model name ending with a character of
B
,
LSPPSE48B
for example. To obtain the model name of a PSE, execute the
display poe pse
command.
Inrush current might occur at PD startup and trigger PSE self-protection, As a result, the PSE stops
supplying power to the PDs. To continue power supply to the PDs, configure this feature to allow
inrush currents drawn by PDs.
IEEE 802.3af and IEEE 802.3at define specifications for inrush current. Support for the
specifications defined by IEEE 802.3af and/or IEEE 802.3at depends on the device model.
Examples
# All high inrush currents drawn by PDs.
<Sysname> system-view
[Sysname] poe high-inrush enable pse 4
