Configure the Time for Recovery from a Power Supply Abnormality of an Interface

If a PSE detects abnormal power supply status of an interface while powering PDs, it automatically disables the PoE function of the interface. After the time for recovery from a power supply abnormality elapsed, it enables the PoE function again, and tries to supply power to the PD of the interface.
