Upgrading Using the GUI

Use the following procedure if you are upgrading using the GUI.

Note

You should always backup the existing software image during the upgrade process. Backing up provides you the option of restoring your wireless controller to its previous configuration. For more information, see Restoring the Backup Image from the GUI.

The wireless software provides two upgrade options:

• Local – Upgrades the wireless software by using the image file that is located either on the local drive or USB device. This is the preferred method of upgrade.
  

  Note

  Before starting the local upgrade, the image file needs to be downloaded to the local drive or a flash device has to be provided with the image file.
• Remote – Upgrades the wireless software by using an image file that is located on an external FTP server. The upgrade program downloads the image file from the FTP server, unpacks it and installs it directly on the system without retaining a local copy of the image file.
  

  Note

  The Wireless Assistant GUI displays Remote as the upgrade option for upgrade from a remote FTP server.
