ODC_BATTERY_PWRDOWN

ODC_BATTERY_PWRDOWN

Description

The ODC_BATTERY_PWRDOWN alarm indicates that the storage battery is powered off.

Attribute

Alarm Severity Alarm Type
Major Equipment alarm

Parameters

When you view an alarm on the network management system, select the alarm. In the Alarm Details field display the related parameters of the alarm. The alarm parameters are in the following format: Alarm Parameters (hex): parameter1 parameter2...parameterN. For details about each parameter, refer to the following table.

Name Meaning
Parameter 1

Indicates the alarm cause.

  • 0x01: The storage battery is powered off due to low voltage.
  • 0x02: The storage battery is powered off due to background control.
  • 0x03: The storage battery is powered off manually and locally.
  • 0x04: The storage battery is powered off due to a high temperature.

Impact on the System

No backup power supply is available to the equipment.

Possible Causes

Possible causes of this alarm are as follows:

  • The storage battery is powered off due to background control.
  • The BAT OFF button on the front panel of the PMU is pressed.
  • The AC input is abnormal.
  • The power module is faulty.
  • The PMU is faulty.
  • The temperature threshold that triggers power-off of the storage battery is set to an inappropriate value.
  • The temperature of the storage battery is high.
  • The temperature sensor of the power module is faulty.

Procedure

  1. Determine the cause for the alarm based on the alarm parameters displayed on the U2000.
  2. Power on the storage battery.
  3. Press and hold down the BAT ON button on the front panel of the PMU for 5 to 10 seconds to power on the storage battery.
  4. Query the threshold for triggering an alarm indicating an exception in the mains supply voltage. Determine whether the threshold is appropriate according to the configuration plan.
    If... Then...

    The threshold is set to an inappropriate value

    Set the threshold to an appropriate value.

    The threshold is set to an appropriate value

    Go to the next step.
  5. Check whether the AC circuit breaker is closed.
    If... Then...

    The AC circuit breaker is open

    Close the AC circuit breaker.

    The AC circuit breaker is closed

    Go to the next step.
  6. Check the AC input power cable.
    If... Then...

    The AC input power cable is incorrectly connected

    Connect the cable correctly.

    The AC input power cable is deteriorating or damaged

    Replace the cable.
  7. Rectify the fault on the power module by following the procedure of handling the ODC_MDL_ABN alarm.
  8. Rectify the fault on the PMU.
  9. Query the temperature threshold for triggering an alarm indicating power-off. Determine whether the threshold is appropriate according to the configuration plan.
    If... Then...

    The threshold is set to an inappropriate value

    Set the threshold to an appropriate value.

    The threshold is set to an appropriate value

    Go to the next step.
  10. Replace the storage battery.
  11. Replace the temperature sensor of the power module.
