Usage guidelines

PDs include standard PDs (which comply with IEEE 802.3af and IEEE 802.3at) and nonstandard PDs. By default, a PSE supplies power to only standard PDs. For a PSE to supply power to nonstandard PDs, enable nonstandard PD detection.

Nonstandard PDs do not support autonegotiating the maximum power with an ONU. Make sure the maximum power configured for a nonstandard PD does not exceed the maximum power supported by the PD.

On an ONU interface or RONU interface, the onu poe legacy enable and uni poe legacy enable commands are mutually exclusive.

Parameters

uni-number: Specifies a UNI by its number in the range of 1 to the number of UNIs on the ONU. The maximum number of UNIs supported on an ONU is 79.

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

high: Sets the power supply priority to high.

low: Sets the power supply priority to low.

Usage guidelines

When the sum of power supplied to PDs attached to UNIs of an ONU exceeds the maximum power of the ONU, the ONU might disable PoE for some UNIs and operate as follows:

·     Power is first supplied to UNIs with higher priority.

·     For UNIs with same power supply priority, the UNI with the smallest number is allocated with power first.
