Using SafeMode to Upgrade Firmware
If you are unable to connect to the Dell SonicWALL 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
appliance, perform the following steps:
1. Connect your computer to the X0 port on the Dell
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 methods:
• 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 at least twenty
seconds. See The Front Panel, on page 10 to locate the
reset button.
• 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 Dell SonicWALL appliance
changes to SafeMode.
The Test light starts blinking when the Dell SonicWALL
appliance has rebooted into SafeMode.
3. Point the Web browser on your computer to
192.168.168.168. The SafeMode management interface
displays.
4. Click Upload New Firmware, and then browse to the
location where you saved the SonicOS firmware image,
select the file and click the Upload button.
5. 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 Default Settings - New!
Use this option to restart the appliance with default
configuration settings.
6. In the confirmation dialog box, click OK to proceed.
7. After successfully booting the firmware, the login screen is
displayed. If you booted with factory default settings, enter
the default user name and password (admin / password) to
access the Dell SonicWALL management interface.
