Using SafeMode to Upgrade Firmware

If you are unable to connect to the Dell SonicWALL security
appliance's management interface, you can restart the
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 Dell SonicWALL
security appliance, perform the following steps:
1. Connect your computer to the X0 port on the 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 more than 20
seconds. The reset button is in a small hole next to the
USB ports.
• Use the LCD control buttons on the front bezel to set the
appliance to SafeMode. Once selected, the LCD displays
a confirmation prompt. Select Y and press the Right
button to confirm. The appliance changes to SafeMode.
The Test light starts blinking when the Dell SonicWALL
security appliance has rebooted into SafeMode.
