You can configure the maximum amount of power that the specified port can deliver to the connected PD, in milliwatts (mW). For PoE, the default value is 15400 mW, and the range is 3000 to 16800 mW. For PoE+, the default value is 30000 mW, and the range is 3000 to 30000 mW. For PoE++ Type 3, the range is 3,000 mW to 60,000 mW and the default value is 60,000 mW. For PoE++ Type 4, the range is 3,000 mW to 90,000 mW, and the default is 90,000 mW.
If the operator limit for a specified port is less than the power drawn by the legacy PD, the legacy PD is denied power.
