Dell Wyse ThinOS Version 9.0 Administrator’s Guide

Upgrade ThinOS 9.x to later versions using Wyse Management Suite

Prerequisites

  • Ensure that you have installed the ThinOS v9.0.1136 image on the thin client.
  • Ensure that you have created a group in Wyse Management Suite with a group token. Use this group token to register the ThinOS 9.x devices.
  • Ensure that the thin client is registered to Wyse Management Suite.
  • Ensure that you have not configured any wallpaper settings on Wyse Management Suite. This is applicable when you are running ThinOS 9.0.1136 build and want to upgrade to 9.0.2081 build. If the wallpaper is configured simultaneously with the ThinOS 9.0.2081 image, the wallpaper fails to download and an error message is displayed. However, this does not affect the upgrade process. Dell Technologies recommends that you disable the Wallpaper settings first, upgrade to 9.0.2081, and then configure the wallpaper again.
NOTE Dell Technologies recommends that you upgrade ThinOS version 9.0.1136 directly to version 9.0.3030 from September 9, 2020 onwards. Do not update ThinOS version 9.0.1136 to version 9.0.2081 or 9.0.2108 after September 9, 2020 as it may result in certificate failure.

Steps

  1. Go to the Groups & Configs page, and select a group.
  2. From the Edit Policies drop-down menu, click ThinOS 9.x.
    The Configuration Control | ThinOS window is displayed.
  3. Click Advanced.
  4. In the Firmware field, select OS Firmware Updates.
  5. Click Browse to browse and upload the firmware.
  6. From the Select the ThinOS Firmware to deploy drop-down menu, select the uploaded firmware.
  7. Click Save & Publish.
    The thin client downloads the firmware and restarts. The firmware version is upgraded.
