Importance
RecommendedDell Technologies recommends applying this update during your next scheduled update cycle. The update contains changes to maintain overall system health. It ensures that the system software remains current and compatible with other system modules (firmware, BIOS, drivers, and software) and may include other new features.
Important Information
- The ThinOS 2408 is updated to completely follow WMS Security Policy > TLS Security Level (default = 1). If your network environment requires a legacy OpenSSL version, then must change the TLS security level to 0, when updating to 2408. Otherwise, the device can lose its network.
- From ThinOS 2408, the VMware Horizon Session SDK package is no longer supported. It is recommended to upgrade ThinOS clients in the environment to the VMware Horizon Client SDK package to avoid issues.
- Starting 2024-11-02, newly manufactured ThinOS client devices with ThinOS 2408 will not contain the Dell ThinOS Teradici PCoIP package or a Teradici PCoIP license entitlement. To enable PCoIP entitlement on all ThinOS client devices that are manufactured on or after 2024-11-02, it is only performed when the ThinOS policy managed by WMS is enabled using Services > WDA Settings > Enable PCoIP Activation License.
- 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 2408.
- 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 the BIOS.
- You cannot boot into ThinOS 2408 (9.5.3102) 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, reboot the device and upgrade again.
- After upgrading to ThinOS 2408, all application packages that are released before 2205, Microsoft AVD package that is released before 2311, Zoom AVD, Zoom Citrix, and Zoom Horizon packages are removed automatically and cannot be installed again. You must install the latest application packages.
