  5. Click Schedule. The J-Web UI requests confirmation to perform the reboot.

  6. Click OK to confirm the operation.

    • If the reboot is scheduled to occur immediately, the device reboots. You cannot access J-Web until the device restarts and the boot sequence is complete. After the reboot is complete, refresh the browser window to see the J-Web login page.

    • If the reboot is scheduled to occur later, the Reboot page displays the time until reboot. You can optionally cancel the request by clicking Cancel Reboot on the Reboot page in J-Web UI.

  7. Click OK to save your changes as a candidate configuration.

  8. If the reboot is successful, click Commit Options>Commit.
