Dell Wyse ThinOS Version 8.6 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. Dell recommends 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, and Wyse Management Suite advanced settings. 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 WDM or Wyse Management Suite.

  Solution for updating firmware using WDM—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. Dell recommends that you create a new App policy to install the package after the firmware update is complete.

• WDM vulnerability is fixed in this release. You must configure either the DHCP or the DNS option/record of the WDM server fingerprint to automatically fetch and validate the fingerprint before checking in to the WDM server. However, there is no impact to the ThinOS device functionality if you do not to configure the fingerprint validation environment. For more information about how to set up fingerprint using WDM, see How to set up WDM fingerprint using Wyse Device Manager.
• Boot up unit without monitor or with monitor power-off.
  • Wyse 5010 thin client, Wyse 5040 thin client, and Wyse 7010 thin client—If the thin client waits for 15 to 20 seconds and the monitor is attached or powered on within 20 seconds, the display is turned on. If the monitor is attached or powered on after 20 seconds, the monitor displays the black screen. Turn on the monitor first, and then turn on the thin client.
  • Wyse 3040 thin client and Wyse 5060 thin client: The client waits until the monitor is attached or turned on.
