hi! I have a problem need your support. 

- We have purchased CSHNU board within 02 difference phases and we have tried to combine those 02 boards (phase-1 and 2) together into a single sub-rack RTN980 but there were alarms SYN_FAILED and COMMFAILED (if i'm not mistake).

- We confirmed that those 02 boards are the same Item, version and BOM.


thanks!

You can refer to the following information for alarm handling.

SYNC_FAIL

Description

The SYNC_FAIL alarm indicates that the batch backup on SCC boards fails.

Attribute

Alarm SeverityAlarm Type
MinorProcessing 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.

NameMeaning
Parameter 1

Indicates the cause of the failure.

  • 0x1F: The database backup fails.

  • 0x20: Software version verification fails on the main and standby SCC boards.

  • 0x21: Communication between the main and standby SCC boards fails.

  • 0x22: The main and standby SCC boards have different data after an upgrade.

  • 0x23: Forced switching occurs between the main and standby SCC boards before database backup is completed.

Parameter 2Always 0xff
Parameter 3Always 0xff

Impact on the System

Data synchronization between the main and standby SCC boards fails, and the switching between the two boards is unavailable.

Possible Causes

  • Cause 1: The main and standby SCC boards have different versions of software.

  • Cause 2: Databases on the main and standby SCC boards are damaged.

  • Cause 3: The main and standby SCC boards have different data after an upgrade.

  • Cause 4: Communication between the main and standby SCC boards fails.

  • Cause 5: Forced switching occurs between the main and standby SCC boards before database backup is completed.

Procedure

  1. Cause 1: The main and standby SCC boards have different versions of software.

    1. Query and record the software versions of the main and standby SCC boards according to Querying the Board Information Report.

    2. If the software versions are different, determine the correct version based on the version mapping table and replace the SCC board with an incorrect version. For details, see Replacing the System Control, Switching and Timing Board.

  2. Cause 2: Databases on the main and standby SCC boards are damaged.

    1. Check whether the system reports the DBMS_ERROR alarm. For details, see Browsing Current Alarms.

    2. If yes, clear the DBMS_ERROR alarm. Then, check whether the SYNC_FAIL alarm is cleared.

  3. Cause 3: The main and standby SCC boards have different data after an upgrade.

    1. Re-install the standby SCC board.

  4. Cause 4: Communication between the main and standby SCC boards fails.

    1. Check whether the system reports the COMMUN_FAIL alarm.

    2. If yes, clear the COMMUN_FAIL alarm. The system will start batch backup automatically.

  5. Cause 5: Forced switching occurs between the main and standby SCC boards before database backup is completed.

    1. Warm reset the alarmed board by following instructions in Warm Reset.

COMMUN_FAIL

Description

The COMMUN_FAIL is an alarm indicating the inter-board communication failure. This alarm is reported when the communication between a board and the SCC board is interrupted.

Attribute

Alarm SeverityAlarm 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.

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.
NameMeaning

Parameter 1

Indicates the ID of the port. The value is always 0x01.

Parameter 2, Parameter 3

Indicates the ID of the path on which the alarm is generated. Parameter 2 is always 0x00. Parameter 3 has the following meanings:

0x03: inter-board Ethernet communication

Parameter 4, Parameter 5

Parameters 4 and 5 are reserved, and their values are always 0xFF.

Impact on the System

The NE configuration cannot be delivered to the board or the board cannot work. Consequently, the services cannot be configured or the protection switching function is unavailable.

Possible Causes

  • Cause 1: A certain board is reset.

  • Cause 2: A board and the backplane are connected improperly.

  • Cause 3: The alarmed board is faulty.

  • Cause 4: A slot is faulty.

  • Cause 5: When the active and standby system control boards switch over, communication between them are interrupted transiently.

Procedure

  1. Cause 1: A certain board is reset.

    1. After you reset the board, the alarm is cleared automatically.

  2. Cause 2: A board and the backplane are connected improperly.

    1. Remove and insert the alarmed board. For details, see Removing a Board and Inserting a Board. Then, check whether the alarm is cleared.

      If...

      Then...

      The alarm is cleared after the board is removed and inserted

      The fault is rectified. End the alarm handling.

      The alarm persists after the board is replaced.

      Clear the alarm according to the solution for the alarm that is generated when a board is faulty.

  3. Cause 3: The alarmed board is faulty.

    1. Replace the alarmed board, and then check whether the alarm is cleared. For details, see Part Replacement.

      If...

      Then...

      The alarm is cleared after the board is replaced

      The fault is rectified. End the alarm handling.

      The alarm persists after the board is replaced

      Clear the alarm according to the solution for the alarm that is generated when a slot is faulty.

  4. Cause 3: A slot is faulty.

    1. Contact Huawei technical support engineers to handle the faulty slot.

      note_3.0-en-us.png

      The slot becomes faulty due to broken pins or bent pins. Remove the board, and use a torch to check whether any pins are broken or bent.

    2. If a vacant slot is available, insert the board in the vacant slot, and then update the data on the NMS so that the board can work normally.

  5. Cause 5: When the active and standby system control boards switch over, communication between them are interrupted transiently.

    1. It is normal that this alarm is reported during the switchover, so this alarm does not need to be handled.
