Important Information
- Do not power off your thin client until the installation is complete.
- If you are using ThinOS 8.6 or earlier versions of ThinOS 9.x, you must first upgrade to ThinOS 9.1.3129 or later versions before upgrading to ThinOS 2308.
- Before upgrading from ThinOS 9.x to later versions, ensure that your system is powered on, and the sleep mode is disabled on the system. If the system has entered the sleep mode, you must send the Wake-on-LAN command through Wyse Management Suite before using any real-time commands. To use the Wake-on-LAN command, ensure that the Wake-on-LAN option is enabled in BIOS.
- You cannot boot into ThinOS 2308 (9.4.3087) or later versions when you perform the following operations:
1. Disable the onboard Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology (PTT).
2. Clear TPM or PTT.
3. Reset BIOS to factory default settings.
- The upgrade may fail if the event log fails to install. In such an event, you may reboot the device and upgrade again.
- After upgrading to ThinOS 2205 or later, all application packages earlier than 2205 are removed automatically and cannot be installed again. You must install the latest application packages.
