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.
1
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.
1
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
