Using the Reset Button 
If you forget the login password to the web management page or could not access the web 
management page, use the reset button on the WS319 rear panel to restore the WS319 to its 
default settings. Perform this operation with caution. After the WS319 is restored to its default 
settings, all custom data and settings will be lost, and the password will be restored to admin. 
When you are powering on the WS319, press and hold the WPS/Reset button for 6 seconds or 
more to restore the WS319 to its default settings.   
The WS319 will restart, which will cause temporary network interruptions.   
 
Restoring Configuration by Importing Backup File 
If your operations fail after multiple configurations or you want to quickly restore the WS319 to 
the familiar configuration state, you can upload the backup configuration file to restore the 
configuration. 
Please regularly back up WS319's configuration file to your computer. For example, back up 
WS319's configuration file before updating its configuration parameters or before restoring it to 
the factory default settings. 
1. Log in to the web management page. 
2. Choose Maintain tab. 
3. In the navigation tree, choose Device Management. 
4. Select Back Up or Restore Settings configuration page. 
After the WS319 is restored to its default settings, change the computer IP address so that it is 
in the same network segment as the 192.168.3.1 default IP address.
