Abstract
Aspects of the disclosure provide a network device that includes a plurality of network ports, a power management controller and port controllers. The plurality of network ports is configured to respectively couple external devices with the network device via network cables, and provide power to the external devices via the network cables. The power management controller is configured to allocate power to the external devices following a power allocation order that is sorted according to power priorities of the external devices. A port controller detects an external device coupled to a particular network port having an operational error. In response to the error detection, the port controller assigns an error priority that is lower than regular power priorities to the external device. The regular priorities are assigned to external devices without the operational error. Further, the port controller provides the error priority to the power management controller for power allocation.
