Collecting Fault Information on the U1900

Collecting Fault Information on the U1900

This topic describes how to collect fault information on the U1900.

Collecting Information with One Click

The LMT for the U1900 allows you to collect the system information, fault information, black box information, operation logs, run logs, and alarm information with one click.

  1. Log in to the LMT and enter the Config mode.
  2. Choose Information Collect > Diagnostic Information Collection.
  3. Select the start time and end time of the fault, set the path for saving files, and click Collect.

    Figure 11-1 shows the page for collecting information with one click.

  4. Click Open and send the log files in the directory to engineers of the service provider.

Obtaining the Black Box

The operation logs cached in a U1900 series unified gateway host are stored in the black box. You can view the black box to check the operation logs. A black box is a .dat file that is named by the IP address of the U1900 and file generation time, and saved in the flash. The file records call stack information that was generated before a system restarts and can be used to locate system restart and breakdown faults.

  1. Run the TFTP server (using the 3CDaemon.exe tool is recommended) and specify a TFTP path.
  2. Change the host IP address of the U1900 to the IP address of the TFTP server, for example 192.168.100.2.

    config system hostip 192.168.100.2

  3. Run the following command to upload the black box. In the command, x indicates the slot number.

    config upload file lastwords slot x

    NOTE:

    If active and standby boards are deployed, you need to collect the black box generated by both boards. Set the slot number (x) to that of the active board and standby board respectively.
