Upgrading the Firmware with Factory Defaults

4. Browse to the location where you saved the SonicOS
Enhanced firmware image file, select the file and click the

Settings.
6. In the confirmation dialog box, click OK. The SonicWALL

interface.

Using SafeMode to Upgrade Firmware

If you are unable to connect to the SonicWALL security
appliance's management interface, you can restart the
SonicWALL security appliance in SafeMode. The SafeMode
feature allows you to recover quickly from uncertain
configuration states with a simplified management interface that
includes the same settings available on the System > Settings
page.
To use SafeMode to upgrade firmware on the SonicWALL
security appliance, perform the following steps:
1. Connect your computer to the X0 port on the SonicWALL
appliance and configure your IP address with an address
on the 192.168.168.0/24 subnet, such as 192.168.168.20.
2. To configure the appliance in SafeMode, perform one of the
following:
• Use a narrow, straight object, like a straightened paper
clip or a toothpick, to press and hold the reset button
on the front of the security appliance for one second.
The reset button is in a small hole next to the USB
ports.
• The Test light starts blinking when the SonicWALL
security appliance has rebooted into SafeMode.
3. Point the Web browser on your computer to
192.168.168.168. The SafeMode management interface
displays.
4. If you have made any configuration changes to the security
appliance, select the Create Backup On Next Boot
checkbox to make a backup copy of your current settings.
Your settings will be saved when the appliance restarts.
5. Click Upload New Firmware, and then browse to the
location where you saved the SonicOS Enhanced firmware
image, select the file and click the Upload button.
6. Select the boot icon in the row for one of the following:
• Uploaded Firmware - New!
Use this option to restart the appliance with your
current configuration settings.
• Uploaded Firmware with Factory Defaults - New!
