Firmware Management

Clicking the Download icon saves the firmware file to a new location on your computer or network. Only uploaded firmware can be saved to a different location.

Boot

Clicking the Boot icon reboots the firewall with the firmware version listed in the same row.


	CAUTION: Clicking Boot next to any firmware image overwrites the existing current firmware image making it the Current Firmware image.


	CAUTION: When uploading firmware to the firewall, you must not interrupt the web browser by closing the browser, clicking a link, or loading a new page. If the browser is interrupted, the firmware may become corrupted.

Updating Firmware Manually

To update firmware manually:

Click the Upload New Firmware... button. The Upload Firmware dialog displays.

Browse to the firmware file located on your local drive.

Click the Upload New Firmware button to upload the new firmware to the Dell SonicWALL Security Appliance.

Click the Upload button. The Firmware Management table displays the new firmware.

Click the Download icon for the version of the uploaded firmware you want. The Opening <filename> dialog displays.

Click OK. A success message displays in the Status bar.

Click the Boot icon for the firmware you just downloaded. A warning message displays.

Click OK. A information message about the time to boot the firmware displays.

Click OK. An information message about the boot status displays in the Status bar.

Another message displays.

Log back in when the log in dialog displays. Both the System > Status and System > Settings pages reflect the firmware update.

Creating a Backup Firmware Image

When you click the Create Backup Settings button, the Dell SonicWALL Security Appliance takes a “snapshot” of your current system state, firmware and configuration preferences, and makes the snapshot the new System Backup firmware image. Clicking Create Backup Settings overwrites the existing System Backup firmware image as necessary.

Use the System Backup file for saving good configurations and then booting them if upgrades or future configurations cause instability or other serious issues. The file is conveniently saved onboard. The date and time the file was created as well as the firmware version in use at the time is displayed in the NOTE above the Firmware Management table. The dates for each item listed in the Firmware Management table are the build dates for the firmware images themselves.

To create a backup file:

Click the Create Backup button. A warning message displays.

Click OK. It may take a few minutes to create the backup file. When the file has been created, the Note above the Firmware Management table displays the date and time of the file was created.

Using SafeMode to Upgrade Firmware

If you are unable to connect to the SonicOS management interface, you can connect to the 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.


	IMPORTANT: It is highly recommended you export the Settings before upgrading the firmware using SafeMode. For how to export settings, see Export Settings .

To use SafeMode to upgrade firmware on the firewall:


	CAUTION: Placing the firewall in SafeMode may make it available to other subnets and, therefore, accessible to non-authenticated users. Disable the SafeMode feature immediately after upgrading the firmware.

Navigate to Network > Interfaces.

In the Network Settings table, click the Edit icon for the MGMT interface. The Edit Interface – MGMT dialog displays.

Ensure you have recorded the chassis IP address for:

•

A firewall from the Chassis IP Address field.

•

An HA pair, the primary and secondary HA units from the Chassis IP Address (Primary) and Chassis IP Address (Secondary) fields.

For Chassis Management, ensure these checkboxes are selected: HTTP, Ping, SSH.

Click OK.

Open a web browser.

Enter the chassis IP address (or chassis IP address for the primary) in the browser. The Chassis management page displays.

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.

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.

In the confirmation dialog, click OK to proceed.

After successfully booting the firmware, the log in screen displays. If you restarted with factory default settings, enter the default user name and password (admin/password) to access the SonicOS management interface.

Navigate to Network > Interface.

In the Network Settings table, click the Edit icon for the MGMT interface.

In Chassis Management, ensure these checkboxes are cleared: HTTP, Ping, SSH.

Click OK.
