Important Information
Do not power off your thin client until the installation is complete.
You cannot boot into ThinOS 2511 (9.6.4029) 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.
From ThinOS 2408, ThinOS is updated to completely follow WMS Security Policy > TLS Security Level (default = 1). If your network environment requires a legacy OpenSSL version, then you must change the TLS security level to 0, when updating to 2511. Otherwise, the device can lose its network.
