HPAD_CROSSTR

HPAD_CROSSTR

Description

The HPAD_CROSSTR alarm indicates that the higher order path adaptation performance crosses the threshold.

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 performance monitoring period.

  • 0x01: The monitoring period is 15 minutes.
  • 0x02: The monitoring period is 24 hours.

Parameter 2, Parameter 3

Indicate the ID of the threshold-crossing performance item.

Impact on the System

The quality of lower order services deteriorates or lower order services are interrupted.

Possible Causes

Possible causes of this alarm are as follows:

  • The clock fails.
  • The performance of the laser on the line board at the opposite end deteriorates.
  • The receive optical power of the line board at the local end is out of range.

Procedure

  1. Check whether the clock tracing configurations at the local end and the entire network are correct.

    If... Then...

    The clock tracing configurations are incorrect

    Modify the clock tracing configurations. After the configured performance monitoring period ends, check whether the alarm is cleared. If the alarm persists, go to the next step.

    The clock tracing configurations are correct

    Go to the next step.

  2. Perform loopbacks at the local end and the opposite end to locate the faulty board.

    If... Then...

    The timing unit at the opposite end reports a higher order adaptation performance event

    The timing unit at the opposite end is faulty Replace the system control, cross-connect, and timing board. Then, check whether the alarm is cleared. If the alarm persists, go to the next step.

    The timing unit at the local end reports a higher order adaptation performance event

    The timing unit at the local end is faulty. Replace the system control, cross-connect, and timing board. Then, check whether the alarm is cleared. If the alarm persists, go to the next step.

  3. Check whether the optical attenuator does not match or is faulty, or whether the optical fiber is broken.

    If... Then...

    The optical attenuator does not match or is faulty

    Replace the optical attenuator.

    The optical fiber is broken

    Replace the optical fiber.

    The optical attenuator and fiber are functioning properly

    Contact Huawei technical support engineers to handle the alarm.
