7. Use the Upgrade Firmware page to enable the device to check for firmware updates or to manually upgrade the firmware.
• To automatically check for firmware updates, check the box next to Check for firmware update when Setup Wizard completes. The security appliance will immediately check for firmware updates after the Setup Wizard is complete. This feature requires that you have an active WAN connection.
• To manually upgrade the firmware from a firmware image stored on your PC, uncheck the box next to Check for firmware update when Setup Wizard completes. Uncheck this box when you do not have an active WAN connection and you have already downloaded the latest firmware image from Cisco.com to your local PC.
8. If you uncheck the box, click Browse to locate and select the firmware image from your PC, and then click Upgrade.
After you click Upgrade, the security appliance starts installing the firmware. This process will take several minutes. Do not disconnect the power or reset the device. Doing so will cancel the firmware upgrade process and could possibly corrupt. The security appliance reboots after the firmware is upgraded. You will be redirected to the login screen when the security appliance boots up.
9. If you choose to automatically check for firmware updates, click Next.
