Administrator Guide

● If you are using ThinOS 8.6, you must upgrade to ThinOS 8.6_807 and apply the latest BIOS updates before upgrading to
ThinOS 9.1.3112.
● If you are using ThinOS v8.5 or earlier versions, you must first upgrade your device to ThinOS 8.6_807 and apply latest BIOS
updates before installing ThinOS 9.1.
● Your system must be powered on and the sleep mode must be disabled on the system. If the system has entered the sleep
mode, you must send the WOL command using Wyse Management Suite before using any real-time commands. To use the
WOL command, ensure that the Wake-On-LAN (WOL) option is enabled in BIOS.
● All device settings are erased after you upgrade from ThinOS 8.6 to 9.1.3112 except the following settings:
○ Wyse Management Suite group token and server settings
○ Static DNS
○
Certificates
○ IEEE802.1x wired authentication settings—When you upgrade from ThinOS 8.6 to ThinOS 9.1.1131, password set for
security types EAP-PEAP-GTC/EAP-FAST-GTC by using Wyse Management Suite or INI parameters are not preserved.
○ Wireless connections
￭ When you upgrade from ThinOS 8.6 to ThinOS 9.1.1131, password set for security types EAP-PEAP-GTC/EAP-FAST-
GTC by using Wyse Management Suite or INI parameters are not preserved.
￭ The WEP/Sharekey security type is changed to Open as they are not supported in ThinOS 9.1.
￭ When you upgrade from ThinOS 8.6 to ThinOS 9.1.1131, the WPA-Personal security type does not work after upgrade.
However, the WPA2-Personal security type works on ThinOS 9.1.
○ Proxy settings
● 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 the low disk space. In this scenario, you must reset to factory default settings for upgrading the
ThinOS client again.
● You cannot boot into ThinOS 9.1 when you perform any of the following operations in BIOS setup:
○ Disable the on-board Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology
(PTT).
○ Clear TPM or PTT.
○ Reset BIOS to factory default settings
● The BIOS version on Wyse 5070 Thin Client must be 1.3.1 or later before you upgrade to ThinOS 9.1. If you upgrade to
ThinOS 9.1 with older BIOS version first and then upgrade to BIOS 1.3.1 or later, the device fails to boot the ThinOS
operating system.
