Boards Cannot Be Registered

Boards Cannot Be Registered

This chapter describes common causes of system reboot faults and provides troubleshooting flowcharts and procedures, alarms, and logs to help identify and rectify these faults.

Roadmap for System Reboot Failures

This section describes how to troubleshoot system reboot failures.

Common Causes

Common causes are as follows:

  • The memory or board is not securely installed, or the memory is not available.
  • CF cards cannot read or write data correctly.
  • No system package is stored in the CF card.
Troubleshooting Flowchart

Figure 4-1 shows the troubleshooting flowchart.

Figure 4-1 Flowchart for troubleshooting a system reboot failure

Troubleshooting Procedure

NOTE:

After the commands are configured to troubleshoot the faults, check the configuration validation mode to ensure that the configurations take effect. Unless otherwise specified, this manual defaults to immediate validation mode.

  • In immediate validation mode, the configurations take effect after the commands are entered.
  • In two-phase validation mode, after the commands are configured, the commit command needs to be run to commit the configurations.

Save the results of each troubleshooting step so that if your troubleshooting attempts fail to correct the fault, you will have a record of your actions to present to Huawei.

Procedure

  1. Check that the board is properly installed.

    If full in or POST failed is as displayed in the following screen obtain in the following picture, check whether the board is securely installed and whether the power meets the requirement.

    Figure 4-2 Screen capture of the device

    If the board is securely installed and the power works properly, go to Step 2.

  2. Check that the self-check of the memory board completed correctly.

    • The memory board is properly inserted if the output information is displayed as the following screen capture.

      Press CTRL+T for full memory test ................ skip
      
    • If fail is displayed, check whether the memory card is securely inserted. If multiple memory cards are available, check whether the memory cards are provided by the same vendor.

    If self-check of the memory board completed correctly, go to Step 3.

  3. Perform a full memory test.

    When "Press CTRL+T to start sdram full test in xx seconds" is displayed on the serial interface, press Ctrl+T to perform a full memory test. If pass is displayed in the output information, the memory works properly. If pass is not displayed in the output information, replace the memory.

    If the full memory test passes, go to Step 4.

  4. Check that the CF cards read and write correctly.

    1. Check whether CF card 0 reads and writes correctly.

      If CF card 0 cannot read or write correctly, the fault shown in the following screen capture will occur. This could be because CF card 0 partition was disrupted or CF card 0 has failed. If the fault persists after the board is upgraded by pressing Ctrl+B, CF card 0 hardware may have failed. Replacing the CF card is recommended.

    2. Check whether CF card 1 has failed. If CF card 1 fails, system reboot will not be affected. Check whether the indicator on the panel of CF card 1 is on. If the indicator is off, CF card 1 probably has not been powered on. If the indicator does not blink for a long period of time after the software is started, CF card 1 is probably reading or writing incorrectly.

    Figure 4-3 Screen capture of Cfcards read and write

    If CF cards read and write correctly, go to Step 6.

  5. Check whether the software package is stored in the CF card.

    Press Ctrl+B when "Press Ctrl+B to enter bootload Menu... 2" is displayed on the serial interface, and output information similar to the following is displayed.

            Bootload Menu(Hiboot Version: 06.11)
    
         1. Boot with default mode
         2. Boot from SATA
         3. Enter ethernet submenu
         4. Set boot file and path
         5. Modify boot ROM password
         6. List file in SATA
         7. Modify System and Chassis Parameters
         8. Modify start mode
         9. Clear expand flag
        10. Clear password for console user
        11. Reboot
        12. Enter TPM Submenu
    
    Enter your choice(1-12): 6
    

    Enter 6, and the CF card Content List Submenu is displayed. Then list all the files and contents within the CF card. If any file with a .cc extension is displayed in the CF card directory, a software package is stored in the CF card. Otherwise, press Ctrl+B.

Slave MPU Cannot Be Registered

This section describes how to troubleshoot the fault that the slave MPU cannot be registered.

Common Causes

Common causes are as follows:

  • The slave MPU has not completed startup.
  • The slave MPU cannot be powered on.
  • The system software package loaded to the slave MPU is different from that loaded to the master MPU.
  • The memory is not properly inserted or is faulty.
  • The CF card of the slave MPU is faulty.
Troubleshooting Flowchart

Figure 4-4 shows the troubleshooting flowchart.

Figure 4-4 Flowchart for troubleshooting the fault that the slave MPU cannot be registered

Troubleshooting Procedure

NOTE:

After the commands are configured to troubleshoot the faults, check the configuration validation mode to ensure that the configurations take effect. Unless otherwise specified, this manual defaults to immediate validation mode.

  • In immediate validation mode, the configurations take effect after the commands are entered.
  • In two-phase validation mode, after the commands are configured, the commit command needs to be run to commit the configurations.

Save the results of each troubleshooting step so that if your troubleshooting attempts fail to correct the fault, you will have a record of your actions to present to Huawei.

Procedure

  1. Check that the startup time of the board has expired.

    The time required for a board to complete registration after it is powered on is called the startup time.

    Generally the startup time of an MPU is less than 3 minutes. If the system software is upgraded and then the device is rebooted, the MPU will complete startup within 20 minutes.

    If the startup time of the board has not expired, wait until the startup time expires. If the startup time of the board has expired, go to Step 2.

  2. Check that the slave MPU is powered on.

    Run the power on slot ? command in the user view. If "<null>" is displayed, all boards have been powered on.

    If the slot number of the slave MPU is displayed, the slave MPU is not powered on. Check whether the power supply of the slot where the slave MPU resides is normal. If the indicator on the slave MPU is on, the power supply of this slot is normal.

    • If the power supply of the slot is abnormal, contact Huawei.
    • If the power supply of the slot is normal but the system still prompts that the slave MPU is not powered on, the power supply module on the slave MPU is faulty. In this case, replace the board.

    If the power supply of the slave MPU is normal but the slave MPU cannot be registered, go to Step 3.

  3. Check that the system software package loaded to the slave MPU is the same as that loaded to the master MPU.

    Connect the console port of the slave MPU to a PC, and then check whether the system software package shown in the field "The start file is" in the feedback information of the console port is the same as that of the master MPU.

    If the system software package loaded to the slave MPU is different from that loaded to the master MPU, go to Step 9.

    If the system software packages loaded to both MPUs are the same but the slave MPU still cannot be registered, go to Step 4.

  4. Check that the memory is properly inserted on the slave MPU.

    If the slave MPU still cannot be registered after the memory is properly inserted, go to Step 7.

  5. Check that the memories are faulty.
    1. Power off the slave MPU. Remove the slave MPU and, after 30 seconds, connect its console port to the COM port of a PC. Re-install the slave MPU and power it on. When the message "Press CTRL+T for full memory test ................2" is displayed, press Ctrl+T to perform a full memory test.

      If a memory fault is detected, a prompt message containing the word "fail" will be displayed. In this case, remove the memory, re-install it, and perform the test again. If the fault persists after several attempts, replace the faulty memory.

      NOTE:
      If no information is displayed on the PC, the memory is faulty. In this case, remove the memory and then re-install it. If the fault persists after several attempts, replace the faulty memory.

    After the preceding operations, if the slave MPU still cannot be registered, go to Step 8.

  6. Check that CF cards work properly.

    Remove the slave MPU and all the CF cards, and then re-install the slave MPU and CF cards.

    If the slave MPU still cannot be registered, go to Step 9.

  7. Contact Huawei and provide the following information:

    • Results of this troubleshooting procedure
    • Configuration, log, and alarm files

The Interface Board Cannot Be Registered

This section describes how to troubleshoot the fault that the interface board cannot be registered.

Common Causes

The common causes are as follows:

  • The board has not completed startup.
  • The board type is not supported by the system software.
  • The board cannot be powered on.
  • The board is not securely inserted.
Troubleshooting Flowchart

Figure 4-5 shows the troubleshooting flowchart.

Figure 4-5 Flowchart for troubleshooting the fault that the board cannot be registered

Troubleshooting Procedure

NOTE:

After the commands are configured to troubleshoot the faults, check the configuration validation mode to ensure that the configurations take effect. Unless otherwise specified, this manual defaults to immediate validation mode.

  • In immediate validation mode, the configurations take effect after the commands are entered.
  • In two-phase validation mode, after the commands are configured, the commit command needs to be run to commit the configurations.

Save the results of each troubleshooting step so that if your troubleshooting attempts fail to correct the fault, you will have a record of your actions to present to Huawei.

Procedure

  1. Check that the startup time of the board has expired.

    The time required for a board to complete registration after it is powered on is called the startup time.

    Generally, the startup time of an interface board is less than 5 minutes. If the system software is updated, an interface board can complete the startup process within 10 minutes.

    Wait until the startup time expires. If the board is still unregistered when the startup time expires, go to Step 2.

  2. Check that the board type is supported by the system software.

    Supported board types vary with system software versions. For the types of boards that are supported by this software version, see the chapter titled "Boards" in the HUAWEI ME60 Multiservice Control Gateway Hardware Description.

    If the board type is supported by this system software version but the board cannot be registered, go to Step 3.

  3. Check that the board is powered on.

    Run the power on slot ? command in the user view. If "<null>" is displayed, all boards are powered on.

    If the slot number of the board is displayed, the board is not powered on. Check whether the power supply of the slot where the board resides is normal. If the indicator on the board is on, the power supply of this slot is normal.

    • If the power supply of the slot is abnormal, contact Huawei.
    • If the power supply of the slot is normal but the system still prompts that the board is not powered on, the power supply module on the board is faulty. In this case, replace the board.

    If the power supply of the board is normal but the board cannot be registered, go to Step 4.

  4. If a new board cannot be registered, remove the board and then re-install it. If the board still cannot be registered, go to Step 5.
  5. Contact Huawei and provide the following information:
