Saving the Module Configuration
To save the new configuration to nonvolatile storage, use the copy running-config startup-config command
from EXEC mode. Once you enter this command, the running and the startup copies of the configuration are
identical.
The following table lists various scenarios when module configurations are preserved or lost.
ResultScenario
The configured module information is lost.A particular switching module is removed and you
used the copy running-config startup-config
command.
The configured module information is lost.A particular switching module is removed and a
different switching module is replaced and you used
the copy running-config startup-config command.
The configured module information is preserved.A particular switching module is removed and the
same switching module is replaced before you enter
the copy running-config startup-config command
again.
The configured module information is preserved.A particular switching module is removed and
replaced with the same type switching module, and
you entered the reload module slot_number
command.
The configured module information is preserved.A particular switching module is reloaded when you
enter the reload module slot_number command.
Shutting Down or Starting Up a Module
You can shut down a module by using the poweroff module command to specify the module by its slot
number in the chassis.
You can power up a module by using the no poweroff module command to specify the module by its slot
number in the chassis.
To determine the slot number for a module, use the show inventory command.
Note
You can use this command with software-controlled modules, such as supervisors, system controllers, line
cards, fabric modules, fan trays, and power supplies. It does not work with modules that are not controlled
by software, such as blank modules installed in empty slots to control airflow.
