NOTE : After you upgrade to the latest version of ThinOS, you can only downgrade to ThinOS 9.1.3129 or later versions using Wyse Management Suite. If you want to downgrade to any previous version, you must use the USB Imaging Tool with Merlin images posted on the www.dell.com/support site.
NOTE: For a given ThinOS release, you can install only the supported packages that are mentioned in the corresponding ThinOS Release Notes available at www.dell.com/support.

4. If you want to install the latest BIOS package, locate the package entry—ThinOS YYMM BIOS package —for your thin client model and click the download icon.
   For information about BIOS installation, see BIOS Installation.
   

File naming convention

ThinOS application packages, ThinOS firmware, and BIOS packages support the following characters in their file names:

• Uppercase letter
• Lowercase letter
• Numeric character
• Special characters—period (.), hyphen-minus (-), and underscores (_)

If you use other characters in file names, the package installation fails. Other files that can be uploaded to the Wyse Management Suite server must follow the same naming convention.

Configuring a ThinOS 9.x client using Wyse Management Suite

It is recommended to optimize centralized configuration server groups for better performance and manageability by maximizing the number of unique customer device configuration groups. A minimal number of Wyse Management Suite groups and settings  should be used to maximize the unique customer device configurations groups. This is applicable to both multitenant and on- premises scenarios.
When you change the group in Wyse Management Suite, the ThinOS 9.x-based thin client displays a message prompting you to restart the thin client immediately or postpone it to the next reboot for applying latest configurations.
When you deploy a new firmware or package using Wyse Management Suite, the thin client displays a message prompting you to start the installation immediately or postpone it to the next reboot.
Configuration comparison between ThinOS 8.6 and ThinOS 9.x
The following is an overview of the major device configuration changes between ThinOS 8.6 and ThinOS 9.x that simplifies the configuration process:
Table 8. Configuration comparisons between ThinOS 8.6 and ThinOS 9.x

ThinOS 8.6 requires INI files with complex parameter syntax
to configure devices.| ThinOS 9.x configuration is completely menu driven.
ThinOS 8.6 user interface is a subset of all possible client configurations and is primarily designed for piloting devices| ThinOS 9.x administrative user interface supports all client commands.
ThinOS 8.6 user interface menu configurations differed from Wyse Management Suite ThinOS menu–based profile configurations.| ThinOS 9.x shares a common administrative user interface with the Wyse Management Suite ThinOS 9.x profile. Hence all client configurations are identical when run from either interface.

ThinOS configuration grouping overview

During the deployment process, you must evaluate various needs of your users to determine all the client configurations that are mandatory to meet the requirements. Few configurations such as monitor resolution or VNC password applies to the device, while others such as broker configurations may only apply to specific users of the device. Redundant configurations may result in performance issues and makes it difficult to manage environmental changes since each device configuration requires to be updated. This issue can be resolved by grouping configurations. ThinOS configuration grouping determines the parameters inheritance. The child group inherits the settings from its parent group. The following table lists the common device configuration criteria that must be considered when creating groups:

Table 9. ThinOS configuration grouping overview

Policy Settings Remote Control Settings (VNC)

Table 9. ThinOS configuration grouping overview (continued)

All other global configurations
Device configurations for a group of clients| Group-based Broker Configurations
Group-based Printer Settings
Group-based Time Zone Settings
Device configurations for a single device| Client-based Terminal Name

Device configurations dynamically selected| ThinOS 8.6 Select Group with device configurations
Device configurations dynamically selected| ThinOS 8.6 SignOn=NTLM (AD.INI) with user configurations
User configurations for a single user| ThinOS 8.6 SignOn=Yes or NTLM with user configurations

ThinOS system variables
ThinOS uses system variables or part of a system variable when defining command values. System variables are often used to define unique values for fields such as terminal name or default user. For example, if the client has an IP address 123.123.123.022, ACC&Right($FIP,3) results in a value of ACC022. Using system variables makes it easier to manage groups of devices that require a unique terminal name or default user.
The following are the ThinOS system variables:
Table 10. ThinOS system variables

10.151.120.15. then the value is 15.
$MAC| Mac address
$CMAC| Mac address with colon.
SUMAC| Mac address with uppercase letters is used.
$DHCP (extra_dhcp_option)| Extra DHCP options for Windows CE unit, including 169. 140. 141. 166. 167. For example, set a string test169 for option tag 169 in DHCP server, and set
TerminalName=$DHCP(169) in wnos.ini. Check terminal name in GUI, and the terminal name will be test169. 166 and 167 is default for CCM MQTT Server and CCM CA validation in ThinOS. You must remap the options from GUI or INI if you want to use $DHCP(166) or $DHCP(167).
$DN| Sign on domain name
$TN| Terminal name
$UN| Sign on username
$SUBNET| For subnet notation, the format is {networkaddress)(network_mask_bits). For example, if the IP address is 10.151.120.15, the network mask is 255.255.255.0, and 10.151.120.0_24 is used.
$F1P| IP address is used in fixed format with 3 digits between separators. For example, 010.020.030.040.ini. Using it in conjunction with the left or right modifier helps to

Table 10. ThinOS system variables (continued)

specified to include file 010.020.030.ini for subnet 010.020.030.xxx.
$SN| Serial number or Service tag
$VN| Version number
Right($xx, i) or and Left($xx. i)| Specifies that the variable is to be read from left or right. The $xx is any of above parameters and the parameter i specifies the digits for the offset of right or left.
&Right($xx, i) or &Left($xx. i)| Specifies whether the variable is read from left or right. The $xx refers to any of the above System Variables. The option ”i” specifies left or right offset digits. For example. the parameter TerminalName=CLT-$SN$RIGHT$07. If the Serial Number (or Service Tag number) of the thin client is MA00256. the terminal name of the thin client is assigned as below:
•First four characters—CLT-
•The rest—The last right-most seven digits of the thin client serial number. The resulting terminal name is displayed as CLT-MA00256.
$AT| Asset Tag must be enabled in the BIOS settings. $AT can be used as terminal name, and the length is limited to 32 characters.

Relationship between INI and Wyse Management Suite group based configurations
This section describes the relationship between INI file parameter–based configurations, and Wyse Management Suite group based configurations. Both INI files and Wyse Management Suite configuration processes have similar functionality. However, the implementation differs. Understanding this concept should greatly reduce the number of redundant configurations and help migrating devices from a file server with INI files to Wyse Management Suite.
Table 11. Relationship between INI and Wyse Management Suite group-based configurations

Global configurations applied at boot to all clients—When using Wyse Management Suite, client configuration policies that applies to all devices should be defined using a Wyse Management Suite Device Policy Parent Group. This is similar to wnos.ini configurations when using a file Server.| Global Configuration File (wnos.ini)| Groups and Config
Device Policy Parent Group
Configurations applied at boot to a group of clients—When using Wyse Management Suite, client configuration policies that apply to a group of device should be defined using Wyse Management Suite Device Policy Child Groups. This is similar
to an INCLUDE file statement with part of a system variable that enables more than one client device to obtain the defined configurations. The advantage of Wyse Management Suite is that it enables multiple Child Group levels, hence allowing nesting of configurations.| Include parameter (wnos \ INC)| Groups and Config
Device Policy Child Groups
Configurations applied at boot to a single client device
—When using Wyse Management Suite, client configuration policies that apply to a specific device can be completed using Wyse Management Suite Device Exceptions. This is similar to an INCLUDE file statement using a full system variable that allows only the selected client to obtain the defined configurations.
NOTE: Device exceptions must be used when required and should be kept to a minimal number of configurations.| Include parameter (WNOS\INC)| Devices

Device configurations dynamically selected from the ThinOS Login menu—The Select Group feature in ThinOS enables you to dynamically select and load configurations and is often used to access multiple virtual environments. In Wyse Management Suite 2.0, this feature is supported only on ThinOS 9 devices.
The Select Group feature can be enabled under Wyse Management Suite PRO Groups & Configs Device Policy Group when creating a Parent Group. Select Group feature
is not supported by Wyse Management Suite Device Policy Child Groups.
NOTE: The Select Group feature is not available when using Wyse Management Suite Standard. A Wyse Management Suite Pro license is required to enable this feature.| SelectGroup parameter (WNOS\INI\GROUPS)| Groups and Configs Device Policy Parent Group

User configurations applied at Login based on Active Directory Domain—When using Wyse Management Suite, ThinOS configurations for a group of users can be defined by
use of the Wyse Management Suite User Policy Group. This feature is similar to AD.INI functionality used by ThinOS 8.6 thdynamically applies configurations to ThinOS at SignOn (NTLMbased on the Active Directory Group Name.
NOTE: ThinOS 9.x Login type (under Login Experience > Login Settings and go to Login Type) must be set to Authenticate to domain controller at the Default Device Policy Group level for Active Directory Domain based configuration to function. If you are using the Active Directory group policy, the login type must be configured ithe child group level of the device policies.| SignOn=NTLM, (WNOS\INI\ AD.INI)| Groups and Configs User Policy Group
User configurations applied at Login based on Username— When using Wyse Management Suite, ThinOS configurations for a single user is defined by use of Wyse Management Suite User Exceptions. It is similar to Username.INI functionality used by ThinOS 8.6 that dynamically applies configurations to ThinOS at Login (NTLM or Yes) based on username.
NOTE: User Exceptions should only be used when required and should be kept to a minimal number of configurations. Excessive use of User Exceptions or User Exception
configurations can affect performance and manageability.| SignOn=Yes or NTLM (WNOS\INI\username.ini)| Users User Exceptions

Wyse Management Suite can define device and user configurations for ThinOS and during boot ThinOS receives a device configuration payload from Wyse Management Suite. Additionally, a user configuration payload is received at Login.
For example, consider a scenario with device policies configured as shown in the following screenshot:

In this scenario, a client that is assigned to Site B Printer Configurations receives a device payload based on the following:

• ThinOS global configurations
• ThinOS EST time zone configurations
• Site B printer configurations
• Device exception configurations

Similarly, at Login, Wyse Management Suite applies user policies based on the Active Directory Group Name or User Exception Policies based on username information.
For more information on how to configure active directory group settings and user exceptions, see the Wyse Management Suite Administrators Guide at www.dell.com/support.

BIOS Installation

Upgrade BIOS
Prerequisites

• Download the BIOS file from www.dell.com/support to your device.
• If you are upgrading BIOS using Wyse Management Suite, register the thin client to Wyse Management Suite.

About this task
NOTE: On thin clients that run ThinOS versions earlier than ThinOS 9.1.6108, you must upgrade the operating system image first, and then upgrade the BIOS after the operating system image is successfully upgraded. Do not upgrade the BIOS and the operating system image together. If you upgrade the BIOS and the operating system image together, the BIOS upgrade is ignored, and you cannot upgrade the BIOS to the ignored version. You must upgrade the BIOS to another version.

Steps

1. Open the Admin Policy Tool on the thin client or go to the ThinOS 9.x policy settings on Wyse Management Suite.
2. On the Configuration Control | ThinOS window, click the Advanced tab.
3. Expand Firmware and click BIOS Firmware Updates.
4. Click Browse and select the BIOS file to upload.
5.  From the Select the ThinOS BIOS to deploy drop-down list, select the BIOS file that you have uploaded.

   The thin client restarts. BIOS is upgraded on your device.
   NOTE: For more information about the latest BIOS version, see the latest Dell Wyse ThinOS Operating System Release Notes at www.dell.com/support.
   NOTE: BIOS upgrade requires a display screen (integrated or external) without which the update fails. In this case, you cannot install the BIOS package again. You must install another BIOS version.
   • From ThinOS 2402, if a monitor is not connected to Wyse 5070, the BIOS update fails. After the monitor is connected, the BIOS update is triggered immediately.
   • If a power adapter is not connected on the Wyse 5470, the BIOS update fails. After the power adapter is connected, you must reboot to trigger the BIOS update again.

Edit BIOS settings
Prerequisites

• If you are using Wyse Management Suite, ensure that you have registered the thin client and synchronize the BIOS admin password. The WDA stores the current BIOS password to unlock the BIOS and apply the required changes. For more information about using the Sync BIOS Admin Password option, see the Dell Wyse Management Suite Administrator’s Guide at www.dell.com/support.
  NOTE: If you have not synced the BIOS password in the WMS server, you can input the current BIOS password in BIOS policy to publish BIOS settings. If you have synced the BIOS password in WMS server, the Current BIOS Admin
  password option in BIOS policy is ignored. WMS server uses the synced BIOS password to publish BIOS settings.

• If you are using the Admin Policy Tool, ensure that you enter the current BIOS admin password in the Advanced > BIOS section.

Steps

1. Open the Admin Policy Tool on the thin client or go to the ThinOS 9.x policy settings on Wyse Management Suite.
2. In the Configuration Control | ThinOS window, click the Advanced tab.
