poe { at-inrush | pre-bt-inrush | bt-inrush } enable

Function

The poe { at-inrush | pre-bt-inrush | bt-inrush } enable command changes the power supply mode of interfaces supporting the PoE++ mode.

The undo poe { at-inrush | pre-bt-inrush | bt-inrush } enable command restores the default power supply mode of PoE interfaces.

By default, interfaces supporting the PoE++ mode on devices provide power in PoE++ mode. That is, the power supply mode is bt-inrush, interfaces not supporting the PoE++ mode on devices provide power in at-inrush mode.

Only the MultiGE interface of an S5720-28X-PWH-LI-AC, the first 12 electrical interfaces of an S5720-16X-PWH-LI-AC, the first 8 electrical interfaces of an S5720I-28X-PWH-SI-AC, and electrical interfaces of the S5720I-6X-PWH-SI-AC, S5720I-10X-PWH-SI-AC, S5720I-12X-PWH-SI-DC, S5730-HI, S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, S5731-H, S5731S-H, S5731-S, S5731S-S, S5732-H, and S6720-SI support this command.

Parameters

Parameter	Description	Value
at-inrush	Sets the power supply mode to PoE+.	-
pre-bt-inrush	Sets the power supply mode to PoE++ compatible. That is, except that the PoE power is 60000 mW, interfaces comply with 802.3at. NOTE: The S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, S5731-H, S5731S-H, S5731-S, and S5731S-S do not support the pre-bt-inrush.	-
bt-inrush	Sets the power supply mode to PoE++. NOTE: The S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, S5731-H, S5731S-H, S5731-S, and S5731S-S do not support the bt-inrush.	-

Usage Guidelines

Usage Scenario

To power the PDs requiring the standard power supply mode, run the poe at-inrush enable command. This command changes the power supply mode of the PoE interface to the PoE+ mode. If most of the parameters supported by the PDs requiring high power comply with 802.3at, run the poe pre-bt-inrush enable command to change the power supply mode of these interfaces to PoE++ compatible.

Precautions

When the poe bt-inrush enable command is configured after the poe af-inrush enable command is configured in the interface, the poe af-inrush enable command configuration is automatically overwritten.
The poe { pre-bt-inrush | bt-inrush } enable and poe single-class enable commands are mutually exclusive and cannot be configured on the same interface.
Changing the power supply mode of a PoE interface will power off the PD connected to this PoE interface.
After the power supply mode of an interface is set to bt-inrush, forcible PoE power supply and PD compatibility check configured on this interface using the poe force-power and poe legacy enable commands respectively do not take effect on this interface.
After the power supply mode of an interface is set to bt-inrush, and the interface detects that it connects to a non-standard PD, confirm whether this interface is connected to a PD. If so, run the poe pre-bt-inrush enable command and the poe legacy enable or poe force-power command to provide power to this PD.
