Dell Wyse ThinOS Version 8.6.1 Administrator's Guide

System configuration and deployment

• USB redirection must be disabled for audio and video devices to use RTME, RTAV, SFB, and JVDI. By default, the USB redirection is disabled on ThinOS. It is recommended that you do not modify the default settings unless you need the USB redirection for audio and video devices.
• ThinOS BIOS policy can be configured using Wyse Management Suite Console, Wyse Management Suite group INI, Wyse Management Suite advanced settings and FTP INI. Dell recommends that you use any one of the methods to configure the BIOS policy. Setting the BIOS policy simultaneously using different methods may cause a policy mismatch, and the device reboots repeatedly. This reboot loop issue is observed when you select the reboot immediately option in the BIOS policy settings section on the Wyse Management Suite console.
• All the installed packages are deleted when you update the ThinOS image version between major releases using FTP or Wyse Management Suite.

  Solution for updating firmware using FTP—Ensure that you have set the PKG install parameters in the WNOS.ini, and the pkg files are uploaded in the directory. After the device reboot, the packages are re-installed automatically.

  Solution for updating firmware using Wyse Management Suite—Wyse Management Suite App policy works only once after the policy is created. The deleted package cannot be reinstalled using the same policy. It is recommended that you create a new App policy to install the package after the firmware update is complete.
