Restoring the device to factory default

Not involved

After configuring the S1850, the customer was unable to access the web interface and wanted to restore the switch to factory settings. The only way to access the device was through the CLI.

You can restore the factory settings in the CLI as follows:

Method 1:

1. Use the reset save command to clear the configuration.

2. Restart the switch.

Method 2:

Delete the startup.cfg file of the switch.

Method 1:

<H3C>reset saved-configuration   //Clear switch configuration

The saved configuration file will be erased. Are you sure? [Y/N]:y   // The device prompts that the saved configuration will be deleted

Configuration file in flash: is being cleared. Please wait ... 

MainBoard:

 Configuration file is cleared.   

<H3C>reboot   // Restart the switch

Start to check configuration with next startup configuration file, please wait.........DONE!

 Current configuration may be lost after the reboot, save current configuration? [Y/N]:n   // The device prompts that the current configuration will be lost after restarting. Do you want to save the current configuration? Select n

This command will reboot the device. Continue? [Y/N]:y   // The device prompts that the device will restart. Do you want to continue? Select Y

Now rebooting, please wait...
