Uploading New SMA Firmware
To upload a new SMA firmware image:
1 Log into your SMA appliance as the administrator and
navigate to the System > Settings page.
2 Select Upload New Firmware and browse to the
location where you saved the SMA image file, select the
file, and click the Upload button. The upload process
can take up to one minute.
3 When the upload is complete, you are ready to reboot
your SonicWall SMA appliance with the new SMA
firmware. Do one of the following:
• To boot the appliance with current configuration
settings, click the boot icon for New Firmware
• To boot the appliance with factory default
settings, click the boot icon for New Firmware
and select the check box to Boot with factory
default settings
4 A warning message dialog is displayed: Are you sure you
wish to boot this firmware? Click Boot to proceed.
CAUTION: After clicking Boot, do not power off the
device while the image is being uploaded to the flash
memory.
After the appliance starts up, the updated firmware
version is displayed on the System > Status page.
Accessing the Appliance using
SafeMode
If you are unable to connect to the SonicWall SMA
management interface, you can restart the appliance in
SafeMode. The SafeMode feature allows you to quickly recover
from uncertain configuration states with a simplified
management interface that includes the same settings
available on the System > Settings page.
You can upload new firmware and restart the appliance using
the old or new firmware while in SafeMode.
You can set the appliance into SafeMode by using a narrow,
straight object, like a straightened paper clip, to press and hold
the reset button on the SMA appliance for five to ten seconds.
When the appliance is in SafeMode, the test LED blinks yellow.
After the appliance is in SafeMode, connect your computer to
X0 and point your browser to the default X0 IP address, then
log in using the administrator credentials. You must set your
computer to an available IP address on the X0 subnet.
For more information regarding SafeMode, refer to the latest
version of the SonicWall SMA Release Notes.
