Using SafeMode to Upgrade Firmware
If you are unable to connect to the Dell SonicWALL NSA E8500
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 NSA E8500,
perform the following steps:
1. Connect your computer to the X0 port on the NSA E8500
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 section, 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 NSA E8500 appliance changes to
SafeMode.

location where you saved the SonicOS firmware image,
select the file and click the Upload button.

current configuration settings.
• Uploaded Firmware with Factory Default Settings - New!

configuration settings.
7. In the confirmation dialog box, click OK to proceed.
