3.4 Management and Configuration

The line card is not manageable.

The line card always uses the default configuration. Any changes you made to the line card are

stored on the MSC. By default, the MSC is allowed to manage every line card. Use the

lcman show

command on the MSC to see a line card’s connection status. If you still cannot manage the line card

from the MSC, the line card’s configuration file may be damaged or the firmware may be old, you

may need to restore the default configuration file or upload new firmware using the line card’s

console port.

Note: The MSC resets the line card after a period of inactivity on the line card. This may

damage the line card if you are uploading the default configuration file or new

firmware to the line card. Use the lcman disable <slot> command on the MSC to

prevent the MSC from managing the line card.

After you upload the file successfully, use the lcman enable <slot> command on

the MSC to allow the MSC to manage the line card again. Refer to the MSC User’s

Guide for details about commands.

3.4.1 Uploading the Default Configuration File via Boot Commands

Obtain the default configuration file, unzip it and save it in a folder. Use a console cable to connect

a computer with terminal emulation software to the line card’s console port. Pull out the line card

and push it back in, you will see the initial screen. When you see the message

Press any key to

enter Debug Mode within 3 seconds

press any key to enter debug mode.

To upload the configuration file, do the following:

1 Type atlc after the Enter Debug Mode message.

2 Wait for the Starting XMODEM upload message before activating XMODEM upload on your

terminal.

Table 9 Local Server Troubleshooting

STEPS CORRECTIVE ACTION

1Refer to Section 3.2 on page 20 to make sure that the subscriber is able to transmit to

the line card.

2 Make sure the computer behind the Ethernet switch has the correct gateway IP address

configured.

3 Check the VLAN configuration (refer to the MSC User’s Guide).

4 Check the cable and connections between the line card and the local server.

5 Try to access another local server.

If data can be transmitted to a different local server, the local server that could not be

accessed may have a problem.
