Impact on the System

A fault of the power module may cause insufficient power supply on the device. As a result, boards will be reset. Services are affected. This fault needs to be rectified.

Possible Causes

  • Cause 1 (EntityTrapFaultID=[136962]): Input overvoltage occurred on the power module.

  • Cause 2 (EntityTrapFaultID=[136963]): Input undervoltage occurred on the power module.

  • Cause 3 (EntityTrapFaultID=[136966]): The power module was installed but not powered on.

  • Cause 4 (EntityTrapFaultID=[136968]): Output overvoltage occurred on the power module.

  • Cause 5 (EntityTrapFaultID=[136964]): Over-temperature occurred on the power module.

  • Cause 6 (EntityTrapFaultID=[136983]): The power module is in overtemperature protection state.

Procedure

  • Cause 1: Input overvoltage occurred on the power module.
    1. Check whether the external power supply is proper. If not, repair the external circuit.
    2. If the fault persists, replace the power module.
  • Cause 2: Input undervoltage occurred on the power module.
    1. Check whether the external power supply is proper. If not, repair the external circuit.
    2. If the fault persists, replace the power module.
  • Cause 3: The power module was installed but not powered on.
    1. Power on the power module.
  • Cause 4: Output overvoltage occurred on the power module.
    1. Check whether the external power supply is proper. If not, repair the external circuit.
    2. If the fault persists, replace the power module.
  • Cause 5: Over-temperature occurred on the power module.
    1. Check whether the fan of the power module cannot work because the air filter is clogged. If so, clean the air filter.
    2. Check whether the ambient temperature is within the allowed range. If the temperature is too high, improve heat dissipation.
    3. Check whether the power supply is normal. If not, repair the external power supply circuit.
    4. If the fault persists, replace the power module.
  • Cause 6: The power module is in overtemperature protection state.

    The handling procedure is the same as that for cause 5.
