Impact on the System

The services that travel along the faulty bus are interrupted or have errors.

The BUS_ERR alarm triggers bus switching.

Possible Causes

Possible causes of the BUS_ERR alarm are as follows:

  • The software version of the service board does not match the software version of the cross-connect board.
  • The active cross-connect board is configured with cross-connections but the standby cross-connect board is not configured with cross-connections.
  • The board is inserted in an incorrect slot or in poor contact with the backplane.
  • The service board is faulty.
  • The chip on the cross-connect board is faulty.
  • The backplane bus from the service board to the cross-connect board is faulty.

Procedure

  1. Query the alarms on the U2000 and locate the cross-connect board that reports the BUS_ERR alarm. Determine the service board used with the cross-connect board according to Parameter 1. Determine the type of the BUS_ERR alarm according to Parameter 4.
  2. If the value of Parameter 4 is 0x01 or 0x02, query the software version of the alarmed cross-connect board and the software version of the service board indicated by Parameter 1. Then, check whether the software versions match.

    If... Then...

    The software versions are compatible

    Go to the next step.

    The software versions do not match

    Upgrade the required software to a mapping version. For details about how to upgrade the required software, see the Upgrade Guide.

    Check whether the alarm is cleared. If the alarm persists, go to the next step.

  3. Query the logic version and software version of the cross-connect board, and check whether the software versions match.

    If... Then...

    The software versions match

    Go to the next step.

    The software versions do not match

    Upgrade the required software to a mapping version. For details about how to upgrade the required software, see the Upgrade Guide.

    Check whether the alarm is cleared. If the alarm persists, go to the next step.

  4. Check whether the service board indicated by Parameter 1 and the alarmed cross-connect board are correctly inserted.

    If... Then...

    The cross-connect board is not inserted securely

    Insert the cross-connect board securely. Check whether the alarm is cleared. If the alarm persists, go to the next step.

    The cross-connect board is inserted securely

    Go to the next step.

  5. Reset (warm) the service board and then check whether the alarm is cleared.

    If... Then...

    The alarm persists

    Perform a cold reset on the service board or replace it. Check whether the alarm is cleared. If the alarm persists, go to the next step.

    NOTICE:

    If the services on the board are not protected, do not reset (cold) or replace the board. Otherwise, the services may be interrupted.

    The alarm is cleared

    Go to the next step.

  6. Reset (warm) the alarmed cross-connect board and check whether the alarm is cleared.

    If... Then...

    The alarm persists

    Reset (cold) the alarmed cross-connect board or replace it. Check whether the alarm is cleared. If the alarm persists, go to the next step.

    NOTICE:

    If no functional standby cross-connect board is available, do not perform the operation. Otherwise, the services may be interrupted.

    The alarm is cleared

    Go to the next step.

  7. Reset or replace the other cross-connect board and check whether the alarm is cleared.

    If... Then...

    The alarm persists

    Contact Huawei technical support engineers to check whether the fault is caused by bent pins on the backplane. If the backplane is damaged, replace the backplane.

    The alarm is cleared

    No further action is required.
