You can upgrade from ThinOS 9.0.xxxx to ThinOS 9.1.2101, or from 9.1.1131 to ThinOS 9.1.2101. If you are running ThinOS 9.0 image, Dell Technologies recommends that you upgrade from ThinOS 9.0.4024 or later version to ThinOS 9.1.2101.
Prerequisites
The thin client must be registered to Wyse Management Suite.
Create a group in Wyse Management Suite with a group token.
Ensure you have downloaded the ThinOS 9.x OS firmware to upgrade.
About this task
Follow the below steps to upgrade:
Steps
Go to the
Groups & Configs page and select a group.
From the
Edit Policies drop-down menu, click
ThinOS 9.x. The Configuration Control | ThinOS window is displayed.
In the left pane, click
Standard.
From the
Standard menu, expand
Firmware, and click
OS Firmware Updates.
NOTE:If you cannot locate the
OS Firmware Updates option under the
Standard tab, use the
Advanced tab.
Click
Browse and select the
ThinOS 9.x OS firmware to upload.
NOTE:Based on your preferred upgrade scenario and the existing ThinOS firmware version present in the group, you must select either the Diff_9.1.2101 or Full_9.1.2101 ThinOS image.
From the
Select the ThinOS Firmware to deploy drop-down menu, select the uploaded firmware.
Click
Save & Publish.
The thin client downloads the firmware to install and restarts. The firmware version is upgraded.
NOTE:When you upgrade from ThinOS 9.0 to 9.1, the thin client downloads all the application packages that are applicable to 9.1. After you upgrade to 9.1, all the application packages are removed and you must reinstall the application packages. Dell Technologies recommends you to upgrade from ThinOS 9.0 to 9.1 without installing the application packages. If you add multiple application packages along with the operating system image in the same Wyse Management Suite group, the upgrade may fail due to low disk space. In this scenario, you must reset to factory default settings for upgrading the ThinOS client again.
NOTE:Ensure that the Wyse 5070 BIOS version is 1.3.1 or later before upgrading to ThinOS 9.1. If you upgrade to ThinOS 9.1 with earlier BIOS version and then upgrade the BIOS version to 1.3.1 or later, the device may fail to boot.
NOTE:There are chances that the upgrade might failed with event log stating Failed to install. In such an event, you may reboot the device and upgrade again.
NOTE:ThinOS 9.0.1136 cannot upgrade the operating system firmware, or install the application packages after September 2021. You can disable time server on ThinOS, change the system time to August 2021, then upgrade the operating system firmware or install the application packages. Dell Technologies recommends you to upgrade to ThinOS 9.1.1131 or later version when the issue is fixed.
