Restore the factory settings of S series switches after a stack splits

14

To restore the factory settings of an S series switch (except the S1700) that has not joined any cluster or stack, run the reset saved-configuration and reboot fast commands, and select N when the system asks you whether to save configurations.
After a switch joins a stack, the stack configurations, including the stack ID, Stack priority, and stack port configuration, are not saved in the configuration file and cannot be deleted by the preceding operations. In this case, to restore the factory settings of a switch, disable all the stack configurations, then run the reset saved-configuration and reboot fast commands, and select N when the system asks you whether to save the configurations.

You can run the reset saved-configuration command in the user view to delete the configuration file for the next startup, so that the switch restarts with the default factory settings. # Delete the configuration file for the next startup. reset saved-configuration The action will delete the saved configuration on the device.

Restore factory settings of the S1700
Restore factory settings of the S1700 using either of the following methods: 1. Hold down the Reset button. When you hold down the Reset button for more than 5s, the switch restarts and restores the factory settings. (If you forget the changed management IP address or password of a switch, you can hold down the Reset button to restore factory settings of the switch.) 2. Restore the factory settings through the web. a. Choose System Management > Reset Factory. b. Click Reset Factory. c. Click Apply.

Whether the configuration of an S series fixed switch stack changes after the stack splits
After a stack is set up, all stack member switches function as one switch on a network. The configuration of the stack is the configuration of the master switch, which is synchronized to the standby switch by the master switch. If a fault occurs on the master switch and the master switch restarts, the standby switch does not restart and function as the master switch. That is, the configuration of the stack does not change.

Split stacks of S series fixed switches
Split a stack of S series fixed switches that is established in stack card connection mode as follows: 1. Run the save command to save the configuration. 2. Run the copy source-filename destination-filename all command to back up the configuration file to all the member switches. 3. Remove stack cables between the member switches. After the stack cables are disconnected, the stack splits. Part of the member switches restart. Remote login may fail because configurations such as the IP address of the stack member switches are the same. Log in to a switch through the console port and perform the following operations. 4. Run the system-view command to enter the system view. 5. Run the stack slot slot-id renumber 0 command to restore the stack ID of the member switch to the default value 0. 6. Power off all the member switches. 7. Remove the stack card. Split a stack of S series fixed switches that is established in service port connection mode as follows: 1. Run the save command to save the configuration. 2. Run the copy source-filename destination-filename all command to back up the configuration file to all the member switches. 3. Remove stack cables between the member switches. After the stack cables are disconnected, the stack splits. Part of the member switches restart. Remote login may fail because configurations such as the IP address of the stack member switches are the same. Log in to a switch through the console port and perform the following operations. 4. Run the system-view command to enter the system view. 5. Run the interface stack-port member-id/port-id command to enter the logical stack port view. 6. Run the shutdown interface { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-10> command to disable the physical member port. 7. Run the undo port interface { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-10> enable command to restore the physical member port to a service port. 8. Run the quit command to exit from the logical stack port. 9. Run the stack slot slot-id renumber 0 command to restore the stack ID of the member switch to the default value 0. 10. Power off all the member switches. Note: Steps 5 to 7 are performed to restore a stack port to a service port, and the operations are performed based on versions later than V200R002.
