3.6 The Line Card is Not Manageable
The line card always uses the default configuration. Any changes you did 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.
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.
3.6.1 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:
1Type atlc after the Enter Debug Mode message.
