   The Auto Reboot option is available for Mobility Access Switches, Aruba Switch, Aruba CX switches, and Branch Gateways.

4. Specify if the upgrade must be carried out immediately or at a later date and time.
5. Click Upgrade. The device downloads the image from the server, saves it to flash, and reboots. Depending on the progress and success of the upgrade, one of the following messages is displayed:
   • Upgrading—While image upgrade is in progress.

6. If the upgrade fails, retry upgrading your device.

   After upgrading a switch, click Reboot.
