poe max-power

poe max-power

Function

The poe max-power command sets the maximum output power of a device.

The undo poe max-power command restores the maximum output power of a device to the default value.

By default, the maximum output power of the device is the total power that the PoE power supply provides for PDs. Therefore, the configured maximum output power must be smaller than the total power that the PoE power supply provides for PDs.

Only the AP8082DN, AP8182DN, AP4050DN-E, AP4050DN-HD, AP7050DN-E, AD9431DN-24X, AD9430DN-24, and AD9430DN-12 support this command.

    • In 802.3at power supply mode, the output power is less than 5.5 W when one expansion card and no USB flash drive is inserted.
    • In 802.3at power supply mode, PoE out is prohibited when two or more expansion cards or a USB flash drive is inserted.

Usage Guidelines

Usage Scenarios

By default, the system automatically obtains the maximum PoE power supported by the device. You can run the poe max-power command to set the maximum output power to ensure stable PoE power supply when the total power of the device is insufficient.

Precautions

If the maximum output power that you set is smaller than the total power required by PDs, PDs with lower priority are powered off or cannot be powered on manually.

Example

# Set the maximum output power of the device to 45000 mW.
