poe ai enable

Use poe ai enable to enable AI-driven PoE.

Use undo ai poe enable to disable AI-driven PoE.

 

 

NOTE:

This command is supported only in Release 6320 and later.

 

Syntax

poe ai enable

Default

AI-driven PoE is disabled.

Views

System view

Predefined user roles

network-admin

Usage guidelines

With AI-driven PoE enabled, the device automatically recovers a PI when it fails. If more than one PI fails simultaneously, the device recovers the PIs one by one in ascending order of PI number.

AI-driven PoE automatically adjusts the power supply parameters to fit the power needs. If you disable AI-driven PoE, the system reverts the parameters to the settings before the adjustment.

AI-driven PoE takes effect only on PSEs that run firmware V147 or later.

·     Firmware earlier than V147—You must use the poe update command to upgrade the PSE firmware and then enable AI-driven PoE on the PSE.

·     Firmware V147 or later—You do not need to re-enable AI-driven PoE after upgrading the firmware if you have enabled the feature before the upgrade.

Examples

# Enable AI-driven PoE.

Usage guidelines

CAUTION

CAUTION:

This command enables the device to supply power to a PD directly without performing a detection of the PD. To avoid damaging the PD, make sure the power provided by the device meets the PD specifications before executing this command.

 

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.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] poe force-power

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

Parameters

pse pse-id: Specifies a PSE by its ID.

Usage guidelines

CAUTION

CAUTION:

Inrush currents might damage the components on the device. Use this command with caution.

 

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. The device supports the IEEE 802.3af and IEEE 802.3at specifications for inrush current.

Parameters

critical: Sets the power supply priority to critical. The PI with critical power priority operates in guaranteed mode. Power is first supplied to the PD connected to the critical PI.

high: Sets the power supply priority to high.

low: Sets the power supply priority to low.

Usage guidelines

When the PoE power is insufficient, power is first supplied to PIs with higher priority.

For PIs with same power supply priority, the PI with the smallest ID is allocated with power first.

If a PoE profile has been applied to a PI, remove the application before configuring the PI in PoE profile view.

Predefined user roles

network-admin

Usage guidelines

During the system warm reboot process (upon execution of the reboot command), the PIs continue supplying power to the PDs but data connections between the PDs and the device are interrupted. After the system reboots, PDs might not re-initiate data connections with the device. Power cycling PIs upon a system warm reboot allows the PDs to re-establish data connections with the device.

Examples

# Enable PI power cycling upon a system warm reboot.

Views

PI view

Predefined user roles

network-admin

Parameters

at: Specifies the IEEE 802.3at standard.

bt: Specifies the IEEE 802.3bt standard.

Usage guidelines

For your configuration to take effect, restore the PI maximum power to the default before you configure this command.

IEEE PoE standards are not forward compatible. For a PI to supply power to PDs, make sure the PoE standard version of the PDs is the same as or earlier than the PoE standard version of the PI.

If a PI operates in IEEE 802.3bt mode and supplies more than 30 W power, changing the PoE standard for the PI will cause the connected PDs to be power cycled. Be cautious when you modify the configuration of this command.

Examples

# Specify the PoE standard as IEEE 802.3at for PI Smartrate-Ethernet 1/0/1.
