Important notes

This section contains information about rmware upgrade and system conguration that you need to know before using ThinOS Lite

version 2.6.

Firmware upgrade and downgrade notication

The Local display 16-bit color option is removed from Wyse 3010 and 3020 zero clients.

System conguration and deployment

• ThinOS BIOS policy can be congured 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 congure the BIOS policy. Setting the

BIOS policy simultaneously using dierent 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 Lite version between major releases—2.5 to 2.6—using FTP, WDM,

or Wyse Management Suite.

Solution for updating rmware using FTP and WDM—Ensure that you have set the PKG install parameters in the WNOS.ini, and the

pkg les are uploaded in the directory. After the device reboot, the packages are re-installed automatically.

Solution for updating rmware 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 rmware update is complete.

• WDM vulnerability is xed in this release. You must congure either the DHCP or the DNS option/record of the WDM server ngerprint

to automatically fetch and validate the ngerprint before checking in to the WDM server. However, there is no impact to the ThinOS

Lite device functionality if you do not to congure the ngerprint validation environment. For more information about how to set up

ngerprint using WDM, see the Dell Wyse ThinOS Lite Version 2.6 Administrator's Guide at www.dell.com/support.
