You can upload any locally saved firmware image file to an access point. The saved file can be an official SonicWall firmware version, or a firmware image downloaded from a manually specified URL.
To upload a firmware image to an access point
Do one of the following to obtain the firmware image and save it on your local workstation:
Download an official SonicWall version as described in Obtaining the Latest SonicWall Firmware.
This procedure leaves you in the Upload Firmware dialog after saving the image file to your local computer.
In the Upload Firmware dialog, click Browse, navigate to the saved image and select it. The Upload Firmware dialog now displays the firmware image name.
In the Upload Firmware dialog, click Upload.
The firmware image is uploaded to the buffer on your security appliance. While uploading, the Status indicates the percentage of the upload.
When the upload completes, the Version column displays the new firmware version. If the access point is connected, the firmware version is automatically pushed to it and the Status changes to a check mark, indicating that the firmware image is Ready, and the Build Date shows the date that the image was created. The access point is now running the new firmware.
