The PMU monitors the AC voltage. This alarm will be generated when the voltage is higher than the threshold (default value :280V).
Y => The AC power supply network and the cable connection in the equipment room are faulty. Perform onsite checks, and contact the power supply departments and property departments to troubleshoot the faults on the power supply network. If the input AC power is normal but the alarm persists, Contact Huawei Customer Service Center.
N => If the current voltage of the AC power is basically within the operating range and the alarm is cleared automatically, you can infer that the power supply is instable. For example, the power supply is interrupted, or overvoltage or undervoltage occurs. Otherwise, contact Huawei Customer Service Center.
