U.S.A.—FCC Part 15 (class B), cUL 60950
Canada—IC ICES-003, CAN/CSA-C22 No. 60950
Europe—EN 55022 (class B); EN 55024
Wireless Usage and Requirements
Radio transmitting type devices (RF module) are present in models with the wireless option. These devices
operate in the 2.4 GHz band (i.e. 802.11B/G/N LAN & Bluetooth).
As a general guideline, a separation of 20 cm (8 inches) between the wireless device and the body, for use of a
wireless device near the body (this does not include extremities) is typical. This device should be used more
than 20 cm (8 inches) from the body when wireless devices are on and transmitting.
Some circumstances require restrictions on wireless devices. Examples of common restrictions include:
•
When in environments where you are uncertain of the sanction to use wireless devices, ask the applicable
authority for authorization prior to use or turning on the wireless device.
•
Every country has different restrictions on the use of wireless devices. Since your system is equipped with a
wireless device, when traveling between countries with your system, check with the local Radio Approval
authorities prior to any move or trip for any restrictions on the use of a wireless device in the destination
country.
•
Wireless devices are not user-serviceable. Do not modify them in any way. Modification to a wireless
device will void the authorization to use it. Please contact the manufacturer for service.
Device Power Supply
Use only the external power supply that comes with your zero client. For power and voltage ratings, see the
serial number label or regulatory label on your device. For power adapter replacement, contact your Dell
Service Representative. For proper replacement compare the labels on both zero client and power adapter to
ensure that their voltages match.
WARNING: Use of any other power adapter may damage your zero client or the power adapter. The damage
caused by an improper power adapter is not covered by warranty.

Use the following information to quickly learn the basics and get started using your thin
client:
•
"Logging In"
•
"Using Your Desktop"
•
"Configuring Thin Client Settings and Connections"
•
"Connecting to Network and Session Services"

TIP: While it can be used in environments without central configuration for basic
connectivity needs, Dell thin clients are designed to be centrally managed and
configured using INI files. In general, it is recommended that you use central
configuration to enable you to automatically push updates and any desired default
configuration to all supported thin clients in your environment (see "Configuring Thin
Client Settings Locally").
NOTE: Some features (noted in this guide) are not supported in SP3.
Logging In
TIP: On your initial connection to central configuration it is recommended that you
connect using a “wired connection” (plug in the network-connected Ethernet cable to
your thin client before starting the thin client) to obtain the configurations desired by
the administrator (connections, system settings, required certificates and so on). This
“wired connection” will also provide any wireless configurations provided by the
administrator through the INI files.
If you must initially connect to central configuration through wireless, use the Ed it
Wireless Connection dialog box (in the Computer menu, click Control Center >
Network Connections > Wireless tab > Add) to create a wireless connection where
you can enter the SSID and encryption configurations required/set up by the network
administrator (see "Network Connections").
After your thin client starts and displays the log in screen, you can log in to your
desktop using the default user name admin and the default password admin. It is highly
recommended that you change the default password by using the User Administration
dialog box in the Control Center (see "User Administration").

Configuring Thin Client Settings
Locally
This chapter contains information to help you set up your thin client hardware, look and
feel, and system settings using the Control Center.
TIP: While it is not recommended to use dialog boxes for configuring thin client system
settings, they are available in case you want to temporarily override central default
configurations or you do not have the option to set up central configuration (smaller
environments). In general, it is recommended that you use central configuration to
enable you to automatically push updates and any desired default configuration to all
supported thin clients in your environment (see "Central Configuration: Automating
Updates and Configurations").
In addition, the Wyse USB Firmware Tool also provides a simple USB imaging solution
for supported devices.
Clicking Control Center in the Computer menu (see "Using Your Desktop") or in the
Connection Manager (see "Configuring Connections Locally") opens the Control
Center.
NOTE: Some features (noted in this guide) are not supported in SP3.
Example of SP2 Control Center
TIP: You can right-click an icon in the Control Center to add the application to your
Favorite Applications area (shown in the Computer menu) or to your Startup Programs.

images are downloaded from the server, see "How to Set Up Automatic Configurations
and Updates."
TIP: Dell devices also support INI updates through WDM’s DDC (see "WDM (Agent
Configuration)").
Use the following guidelines:
•
Do not use INI files - Use this option when you want to use only locally configured
settings (using the thin client dialog boxes available) and do not want to use
available INI files on the network or local INI files.
•
Use INI files from server only - Use this option when you want to use INI files from
the specified server only (for example, you do not want to use local INI files or do
not want to allow INI use when disconnected from the server for security reasons).
When using this option you can direct the thin client to the server location through
either of the following ways:
•
·
DHCP Server - Select the Get INI and Upgrade server details via DHCP check
box. The DHCP server will direct the thin client (using DHCP options) to the
server location where the INI files and image updates reside.
·
Manually entered server address - Clear the Get INI and Upgrade server details
via DHCP check box and enter the static INI Settings (INI Server URL, and
optionally the Username and Password of the server, if selecting the Server
requires authentication check box).
If server is available, use INI files from server only; otherwise use local INI files Use this option when you want to use INI files from the specified server, however,
local INI files can be used if that server is unavailable. When using this option you
can direct the thin client to the server location through either of the following ways:
·
DHCP Server - Select the Get INI and Upgrade server details via DHCP check
box. The DHCP server will direct the thin client (using DHCP options) to the
server location where the INI files and image updates reside.

requires authentication, select the Server required authentication check box and
enter the Username and Password.
•
Restore factory defaults when updating - When selected, removes all
local-machine customizations when software is updated from the file server. This
setting is enabled by default and is recommended. However, if you want to keep
locally defined connections or custom changes to installed applications, you can
clear this check box.
TIP: In order to update with the Restore factory defaults when updating option
disabled, you must have a properly set-up addons folder with a directory file that
defines which software versions you want on the thin client. Moreover, it may take
two full reboots to restore the latest software as well as your customizations.
•
Force base system update - If you want to install the image and add-ons available
on the file server regardless of whether or not they are the same as the currently
installed image and add-ons on the thin client, select this check box.
TIP: The Restore factory defaults when updating option and the Force base system
update option are useful when you want to fully restore the unit to factory defaults.
These options remove any customizations and install only the base image supplied
by Dell.

Network Connections
Use the Network Connections dialog box (click Network Connections) to configure
the settings you want for supported network connections. Use the Wired, Wireless,
Mobile Broadband, VPN, and DSL tabs to view and manage (add, edit, and delete) the
list of network connections configured on the thin client. By default, your thin client
obtains information from the DHCP server about network connections (highly
recommended), but you can manually enter connection information (provided by your
network administrator) to connect to other networks (experienced users only).
IMPORTANT: Currently, 802.1x configuration (using the Enable802 INI parameter) is
supported only for Wired connections and supported authentications are EAP-PEAP
(MSCHAPv2) and EAP-TLS using SCEP.
Supported seamless 802-1x authentication works with SuSE-based Linux thin clients by
using Active Directory domain user credentials for EAP-MSCHAPv2 authentication (see
"EAP-PEAP (MSCHAPv2) Authentication Workflow"). EAP-TLS is certificate-based
authentication which uses SCEP for certificate enrollment (see "EAP-TLS
Authentication Workflow"). The following diagram depicts communication between
the components in an 802.1x Linux thin client solution.
NOTE: EAP-TLS security requires client side and server side certificates for mutual
authentication. Every end user and client, including the authentication server that
participates in EAP-TLS, must have at least the following two certificates:
Client certificate signed by the certificate authority (CA)
Copy of the CA root certificate
Configuring Thin Client Settings Locally
39
EAP-PEAP (MSCHAPv2) Authentication Workflow
When a Linux thin client is initially connected to the network, the thin client will obtain
Guest VLAN resources by default (that is, it should be able to reach Active Directory,
DNS, and INI servers to fetch the INI configurations required for Active Directory
Domain User Authentication, 802-1x, ImportCerts, and so on.
The following steps are involved in the 802-1x authentication:
1. When the thin client boots up, it remains in the Guest VLAN and downloads the ini
configuration from the INI server.
2. The INI file must have the configurations for 802-1x, Active Directory server, and
Domain and Import certs. If you are pushing a CA certificate via Wyse Device
Manager (WDM), Imports Certs INI is not required, but you must be sure that the CA
certificate name is correct in the 802-1x INI parameter (see Reference Guide: Dell®
Wyse Enhanced SUSE Linux Enterprise SP2/SP3 INI Files).
3. Once the INI is downloaded to the thin client, the user obtains the domain which is
configured via the INI in the domain drop down list at the user GDM login screen.
4. The user must then select the domain, and enter the user domain credentials to log
in to the thin client. Domain User authentication is performed against the AD server
named in the INI configuration.
5. If the domain user login is successful and the correct CA certificate is available, then
802-1x authentication will begin (users will see the network progress icon on the
taskbar) and the thin client will move to Authorized VLAN.
If 802-1x authentication fails due to any wrong 802-1x configuration (or if the CA
certificate has expired), the thin client will automatically fall back to Guest VLAN,
with a notification message ("Failed to connect to trusted network. Please contact
your system administrator") displayed to the user at the right corner of GNOME
panel (taskbar).
6. When a user logs out or restarts the thin client, the thin client will again move to
Guest VLAN by sending an EAPOL logoff to switch and disabling the 802-1x
configuration at the Network Connections applet.

EAP-TLS Authentication Workflow
When a Linux thin client is initially connected to the network, it should be able to obtain
the Guest VLAN resources by default (that is, it should be able to reach AD, DNS, SCEP
and the INI server to fetch the INI configurations required for Active Directory Domain
User Authentication, 802-1x, SCEP, and so on. EAP-TLS 802-1x authentication can be
configured via INI in 2 different modes: Machine Authentication and User
Authentication.
•
EAP TLS - Machine Authentication - The following steps are involved with 802-1x
authentication:
1. When the thin client boots up, it remains in the Guest VLAN and downloads the
INI configuration from the INI server.
2. The INI file must have the configurations for 802-1x (EAP-TLS with AuthMode set
for Machine Authentication) and SCEP.
3. Once the INI is downloaded to the thin client, SCEP client enrolls the client
certificate with Machine hostname and Domain configured in the INI.
4. 802-1x EAP-TLS machine authentication will then begin (you can view the
network progress icon in the taskbar) and the thin client will move to an Authorized
VLAN.
5. If 802-1x authentication fails due to any wrong 802-1x configuration, the thin
client will automatically fall back to the Guest VLAN, with a notification message
("Failed to connect to trusted network. Please contact your system administrator") in
the right corner of the GNOME panel (taskbar). The user receives the same
notification in the case of an expired CA certificate.
6. When a user restarts the device, the thin client will again move to the Guest VLAN
by sending an EAPOL logoff to switch and disable the 802-1x configuration at the
Network Connections applet.
Example of the INI configuration for 802-1x TLS Machine authentication.
Enable802=yes Authentication=TLS
PromptPassword=no CACertificate=scep
UserCertificate=scep PrivateKey=scep
PrivateKeyPassword=ZG90MXg=
AuthMode=Machine
•
EAP TLS - User Authentication - The following steps are involved with 802-1x
authentication:
1. When the thin client boots up, it remains in the Guest VLAN and downloads the
INI configuration from the INI server.
2. The INI file must have the configurations for 802-1x, AD server, DomainList, and
SCEP.
3. Once the INI is downloaded to the thin client, the user obtains the domain that is
configured via INI in the domain drop-down list on the GDM login screen.
4. The user must then select the domain, and enter their domain credentials to login
to the thin client. Domain User authentication is performed against the AD server
mentioned in the INI configuration.
5. If domain user login is successful, then the user certificate will be enrolled via
SCEP and 802-1x authentication will begin (you can view the network progress icon
on the taskbar) and the thin client will move to an Authorized VLAN.
6. If 802-1x authentication fails due to any wrong 802-1x configuration, the thin
client will automatically fall back to the Guest VLAN, with a notification message
("Failed to connect to trusted network. Please contact your system administrator") in
the right corner of the GNOME panel (taskbar). The user receives the same
notification in the case of an expired CA certificate.
7. After user log-off or a restart of the device, the thin client will again move to the
Guest VLAN by sending an EAPOL logoff to switch and disable the 802-1x
configuration at the Network Connections applet.

NOTE: A successful TLS authentication will display security connection information
in the Connection Information dialog box as shown below.
Example of the INI configuration for 802-1x TLS User authentication.

Chapter 3
SCEP Cl ient Configuration
Use the SCEP Cl ient Configuration dialog box (click SCEP Cl ient Configuration) to
direct the thin client to use automated certificate enrollment (SCEP offers a standard
interface to communicate with a Certificate Authority).
SCEP (Simple Certificate Enrollment Protocol) is a PKI communication protocol which
leverages existing technology by using PKCS#7 and PKCS#10. It includes several
properties that allow it to do an automatic enrollment without manual interaction. The
typical usage scenarios of SCEP are large network environments with many network
devices that require automatic enrollment of certificates.
TIP: Enrollment and usage of SCEP generally follows the following work flow:
1 -Obtain a copy of the Certificate Authority (CA) certificate and validate it.
2- Generate a CSR and send it securely to the CA.
3 - Poll the SCEP server in order to check whether the certificate was signed.
4 - Enroll/re-enroll as necessary in order to obtain a new certificate prior to the
expiration of the current certificate.
5 - Retrieve the CRL as necessary.
Use the following guidelines:
•
Add ing a SCEP Cl ient Configuration Certificate - Click Add to open the SCEP
Certificate Enrollment Settings dialog box, enter a Certificate Name (Certificate file
name must be unique), SCEP Server URL, Enrollment challenge password, CA
Distinguished Name, and then click OK to create a SCEP certificate entry for a CA
enrollment.
NOTE: After adding a certificate, the newly added certificate entries will be
displayed in the SCEP Cl ient Configuration dialog box.
•
Ed iting a SCEP Certificate - Select a certificate from the list, click Ed it, and
configure the certificate settings.
•
Deleting a SCEP Certificate - Select a certificate from the list, click Delete, and then
confirm.
•
Enroll a SCEP Certificate - Select a certificate from the list and click Enroll. After
successful certificate enrollment, the Status column will display as Enrolled (in a
case of failure, the Status column will display as Failed.

the thin client (on the USB Devices tab). You can deny a device class, but still permit a
USB device in that class to be used, by adding it to the Devices list of the Configuration
tab.
Use the following guidelines:
•
Enabl ing USB devices - Select the Enabled check box (default).
•
Allowing or denying USB device classes - On the Configuration tab, select or clear
the check box of a device class in the Devices list to allow or deny its use. For
example, select Smart Card Devices to permit USB smart card devices to be used to
log into virtual machines.
•

box, enter a Device Name, select a class for the device from the Class list, enter the
Sub Class, Vendor ID, Protocol, and Product ID, and then click Add. After you reboot
your thin client, the name of the new device appears on the Configuration tab.
TIP: You can obtain device Class, Sub Class, Protocol, Vendor ID, and Product ID
information by plugging the device into the USB port of your thin client and viewing
the information displayed in the USB Devices tab.
•
Allowing or denying a USB device - After you add a USB device, its name appears
on the Configuration tab. Select or clear a USB device check box to allow or deny its
use.
CAUTION: Use caution when using TCX USB Virtualizer on a terminal server, as

User Administration
Use the User Administration dialog box (click User Administration) to view and edit
passwords for all users (both built-in defaults and those defined through INI files) and
to enable automatic login for a user (automatically log in a user at system start up). In
addition, you can manage SSH root User password and login (using the SSH root User
tab).
CAUTION: While this dialog box allows you to edit the passwords and automatic login
for users of the thin client, you must use central configuration (INI files) to add or delete
users beyond the built-in default users provided. In general, it is recommended that you
use user.ini files to manage (add, edit, or delete) users for normal use cases. For
example, a new user should be created through a user.ini file with the appropriate
privilege level defined in the text file.
To edit a user password, select the change password check box you want, and then

Administrators Only: Details on Using TightVNC Viewer for Remote
Administration (to Shadow/Monitor a Thin Cl ient)
TightVNC Server is installed locally on the thin client (see "VNC Server"). It allows a thin
client to be shadowed/operated/monitored from a remote machine on which
TightVNC Viewer is installed (TightVNC Viewer is available from the TightVNC Web site;
it is also included as a component of WDM software and must be installed on the
remote/shadowing machine before use).
TightVNC (Server and Viewer) allows a remote administrator to configure or reset a thin
client from a remote location rather than making a personal appearance at the thin
client site (VNC is intended primarily for support and troubleshooting purposes).
TightVNC Server starts automatically as a service at thin client startup. The service can
also be stopped and started by using the Services window (opened by clicking Start >
Control Panel > Administrative Tools > Services).
Before an administrator on a remote machine (on which TightVNC Viewer is installed)
can access a thin client (with TightVNC Server) the administrator must know the:
•
IP Address (or valid DNS name) of the thin client that is to be shadowed/operated/
monitored (see "Viewing System Information"). To obtain the IP address of an
administrator thin client, hover the mouse arrow over the VNC icon in the system
tray of the Administrator taskbar.
•
Security Password of the thin client that is to be shadowed/operated/monitored
(see "VNC Server").

Central Configuration: Automating
Updates and Configurations
This appendix describes how to set up your environment to provide your thin clients
running Wyse Enhanced SLE with automatic updates and configurations in three simple
steps.
It includes:
•
"How INI files Are Employed"
•
"How to Set Up Automatic Configurations and Updates"
TIP: Dell thin clients do not require device management software. They are configured
to obtain their IP address, as well as the location of firmware and configuration
instructions, from a DHCP server. However, you can use WDM or the Wyse USB
Firmware Tool for a more hands-on management of client configurations and updates.
For information about configuring thin clients to communicate with a WDM server, see
"WDM (Agent Configuration)" and related INI parameters in Reference Guide: Dell®
Wyse Enhanced SUSE Linux Enterprise SP2/SP3 INI Files.
IMPORTANT: If you have cloud clients running on different platforms (for example
different classes—Z class, R class and so on) in the same network, see "Mixed
Environment Imaging (An Enhanced Method of Upgrading)."
92
Appendix A
How INI files Are Employed
INI files (created and maintained by the network administrator) determine how the thin
client is configured and updated. The thin client accesses INI files from the server
during the initialization process. Typically, INI files are accessed through FTP, HTTP, and
HTTPS; if no protocol is specified, the default is anonymous FTP.
IMPORTANT: The INI file processing hierarchy is as follows:
•
Scenario 1 - MAC.ini exists. The MAC.ini file is processed and if the Include=WLX.ini
statement is included, then the WLX.ini file is processed.
•
Scenario 2 - MAC.ini exists and {username}.ini exists. The MAC.ini file is processed
and if the Include=WLX.ini statement is included, then the WLX.ini file is processed.
Once the credentials are provided, the {username}.ini file is processed.
•
Scenario 3 - WLX.ini exists. The WLX.ini file is processed.
•
Scenario 4 - WLX.ini exists and {username}.ini exists. The WLX.ini file processed.
Once the credentials are provided, the {username}.ini file is processed.
•
Scenario 5 - No ini files exist. Local configuration is applied.
INI files are employed as follows:
•
wlx.ini - This is the global INI file. One wlx.ini file is available to all users. It contains
global parameters for all thin clients accessing the server. If the operating system
cannot find wlx.ini, it defaults to wnos.ini.
•
{username}.ini - This file is unique to each user. The {username}.ini file contains the
connection profile for each user. Parameters in the user profile generally supersede
the identically named global parameters.
•
$MAC.ini - This file can be used for device-specific configuration. If the thin client
locates this INI file (it is stored in the same directory as wlx.ini), wlx.ini is not
accessed, unless you use the include=wlx.ini parameter.
Note also that the placement of the include=wlx.ini parameter within the $MAC.ini
file will dictate which value will take priority for a same specific parameter that is
contained in both the wlx.ini file and the $MAC.ini file but is defined differently
(different values for the same parameter).
For example, if the wlx.ini file has parameterA=valueB, and the $MAC.ini file has the
same parameterA=valueC, then:
- If the include=wlx.ini parameter is included in the $MAC.ini file before the
parameterA=valueC statement, then the wlx.ini parameterA=valueB is discarded and
parameterA=valueC (from the $MAC.ini file) is the final value used.
- If the include=wlx.ini parameter is included in the $MAC.ini file after the
parameterA=valueC statement, then the $MAC.ini parameterA=valueC is discarded
and parameterA=valueB (from the wlx.ini file) is the final value used.
When a thin client is initialized, it accesses the global wlx.ini file. When a user logs in,
the thin client accesses the user’s unique {username}.ini file. For detailed information
on constructing and using Wyse Enhanced SLE INI files, see Reference Guide: Dell®
Wyse Enhanced SUSE Linux Enterprise SP2/SP3 INI Files.
TIP: If both PNLite and a user profile are being used, the username must be defined in
the Windows domain to be used, and the password must be the same for the domain
and the profile.

93
How to Set Up Automatic Configurations and Updates
For a Dell thin client running Wyse Enhanced SLE to successfully access INI files and
update itself from a server, you must set up the server with the correct folder structure
(where the INI files and other update files are located), direct the thin client to the
server, and then reboot or start the thin client.
After DHCP and servers are configured and available, the thin client checks (at each
boot up) to see whether or not any updates are available on a predefined server (DCHP
Option #161specifies the server URL, DCHP Option #162 specifies the root path to the
server). If updates are available, the updates are automatically installed.
Step 1: Prepare the Root Directory and Folder Structure on the Server
Set up the following folder structure on your server under the C:/inetpub/ftproot folder
(for FTP) or C:/inetpub/wwwroot folder (for HTTP or HTTPS) and place your INI files
and other necessary files inside the structure as noted (this list describes the folder
structure, starting with the root directory).
/wyse/
/wyse/wlx
The root directory. It stores the wlx folder and the addons
folder.
It also stores the following files, which are used for imaging and
updating devices:
•
Latest-image.raw
•
Latest-image.raw.info
The main INI configuration folder. It stores the following:
•
wlx.ini file and $MAC.ini file
•
bitmap folder

/wyse/wlx/bitmap
The folder where you can place custom images you plan to
use.
/wyse/wlx/certs
The folder where you can place the CA certificates that can be
imported to a thin client.
Note: Use the Certs and ImportCerts INI parameters in the
wlx.ini file to import the certificates to thin clients.
/wyse/wlx/ini
The folder where you can place the {username}.ini files.
/wyse/addons
The folder where you can place the add-ons you want to use.
It also stores the directory file and the *.rpm packages available
to be installed on the thin client. The directory file should list all
available add-ons. The directory file is required in the addons
folder to guarantee that add-ons are properly located.
NOTE: If you want to do an update with the Preserve changes
option enabled, ensure that your addons folder includes a copy
of your current add-ons. The system may require two reboots
to fully update the firmware and add-ons while preserving local
changes.

Appendix A
The following figure shows how to set up the folder structure on your file server and
where to place INI files and other necessary files inside the structure.
Be sure to create/activate the two required MIME Types (.ini and .) under IIS (on a per
site basis) to enable downloading. Also be sure your Web server can identify the file
types used by Dell thin clients.
To create/activate the .ini MIME Type:
1. On your IIS server, use the File Types menu to add a New Type.
2. In the File Type dialog box, enter the Associated extension .ini and Content type
(MIME) text/plain.
3. Click OK to apply the settings.
To create/activate the . MIME Type:
1. On your IIS server, use the File Types menu to add a New Type.
2. In the File Type dialog box, enter the Associated extension . and Content type
(MIME) text/plain.
3. Click OK to apply the settings.
For detailed instructions on adding the .ini and . MIME Types, see Knowledge Base
Solution #21581 (go to http://www.dell.com/wyse/knowledgebase and search for
21581).

Step 2: Direct the Thin Cl ient to the Server
After you set up the folder structure and populate it with the correct files, you must
then direct the thin client to the location of the server by one of the following ways:
•
DHCP (see "Using DHCP")
•
Manual direction (see "Manually Configuring the Server Location")
IMPORTANT: Using DHCP is strongly recommended.
Using DHCP
When using DHCP to direct the thin client to the location of the server
(recommended), information about the server and root directory is obtained from the
following DHCP options:
•
161 - The server.
•
162 - Root path to the server (ftp/http/https).
·
If no root path is defined, /wyse is assumed.
·
If a root path is defined, the additional path will be appended to the URL supplied
by option 161.
•
184 - (Optional) Server username (to server specified in option 161).
•
185 - (Optional) Server password (to server specified in option 161).
IMPORTANT: Check-in for firmware updates is done early in the boot process. For that
reason, changes in DHCP information may not be propagated to a unit until a full boot
is completed. However, you can avoid this by forcing a renewing of the DHCP lease,
which makes sure that the unit has the latest file-server location before the next
firmware check. Simply, right-click the Network Manager icon, click Enable
Networking to disable it, right-click the Wireless Manager icon, and then click Enable
Networking to enable it again (the DHCP lease is renewed).
For general instructions on adding DHCP Options #161 and #162, see Knowledge Base
Solution #16132 (go to http://www.dell.com/wyse/knowledgebase and search for
16132).
Use the guidelines shown in Table 3 when creating and adding the DHCP options you
need.

Server (ftp/http/https)
Optional string. If this is an IP address or resolvable
hostname, the protocol is assumed to be FTP;
however, it may be the leading portion of a URL
that specifies another protocol. If using the URL
form, it should not include a trailing slash (for
example, http://server.example.com or ftp://
192.168.0.1).
162
Root path to the server (ftp/
http/https)
Optional string. The relative directory starting from
the root directory must be given. For example, on
an FTP server, the full directory may be C:/
Inetpub/ftproot/wyse, where wyse is the
directory that contains the firmware. In this
example, the correct string value for this DHCP
option is /wyse.
On a Linux server, an FTP user-based directory
might be /home/test/wyse. In this example, if
the FTP user is test, then the FTP root path is
/wyse and not the full path (/home/test/wyse).
This value should use URL path notation (start with
a forward slash, /, and use a forward slash as folder
separators).
181
Wyse PN Server
Optional string. IP address or FQDN of the PNLite
server.
182

Server Username
Optional string. Username to use when
authenticating to the server specified in Option
161.
185
Server Password
Optional string. Password to use when
authenticating to the server specified in Option
161.
186
WDM IP Address
Optional binary IP address of the WDM server. This
option can specify up to one WDM server.
191
XenDesktop DDC URL
Optional string. See also "Desktop Appliance."
194
WDM FQDN
Optional FQDN of the WDM server. This option
can specify up to one WDM server.
Central Configuration: Automating Updates and Configurations
97
Manually Configuring the Server Location
To manually configure the file server location (not recommended), open the INI and
Upgrade Settings dialog box (Computer > Control Panel > INI Settings), clear the Get
INI and Upgrade server details via DHCP check box, and then enter the URL (for HTTP
or HTTPS; FTP URL is allowed for FTP) for the INI server in the INI Server URL text box.
For more information, see "INI (and Upgrade) Settings."
TIP: You can also click Image Upgrade Settings to configure the INI and upgrade
settings as described in "Configuring the Image Upgrade Options."
Step 3: Reboot the Thin Cl ient
After you reboot (or start the thin client), the thin client will look in the defined root
path for the latest available image and update if necessary. Additionally, it will check the
directory file in the addons folder to see if any updates for installed add-ons are
defined. Add-ons that exist in the addons folder but are not listed in the directory file,
will be ignored during update check-in.

Mixed Environment Imaging (An
Enhanced Method of Upgrad ing)
This appendix details the improved method of upgrading a mixed environment of cloud
clients using the mixed_env_upgrade addon (installed on the cloud client) and the
Upgrade.Image_RootPath=/…./$PLATFORM/…. key (contained in the ini file). This new
method improves the upgrade process so that there is control over limiting the
upgrade to particular platforms of cloud clients in the network.
When cloud clients running on different platforms (for example different classes—Z
class, R class and so on) are in the same network and are upgraded using a single
upgrade image on the server, the cloud clients that are incompatible with the current
image will not upgrade properly. The problem occurs because all the cloud clients are
looking in the same path on the server for the upgrade image. The new method of
upgrading addresses this issue and provides a way of upgrading only cloud clients in
the network for which the upgrade is intended. The mixed_env_upgrade addon will
parse the ini setting and set the root path on the cloud client. This root path will be
relative to the type of cloud client platform, and therefore after setting the root path,
the cloud clients will be looking in different locations on the server for the upgrade
image intended for their specific platform.
NOTE: The new addon code will be added under the wyse/addons directory. The addon
is an ini parser. If the $PLATFORM is found in the Upgrade.Image_RootPath then the
parser will replace the $PLATFORM with the cloud clients platform type and set the root
path to the value of Upgrade.Image_RootPath. For example if the platform type is
Z50D, then the RootPath will be set to /…./Z50D/…. The root path setting will be saved
in the temporary registry. Platform types include C50LE, D50D, D50Q, R50L, R50LE,
X50m, Z50D, Z50S, and Z50Q.
Example:
For ini setting:
Upgrade.Image_RootPath=/xyz/$PLATFORM/dir1/dir2/
The Z50D cloud client will obtain the image from:
ftp://xx.xx.xx.xx/xyz/Z50D/dir1/dir2/
The Z50S cloud client will obtain the image from:
ftp://xx.xx.xx.xx/xyz/Z50S/dir1/dir2/
IMPORTANT: The root path is case sensitive.
Resetting the Root Path: The RootPath on the cloud client can be reset back to default,
by setting any of the following ini settings:
1. FirmWareRootPath ini settings
2. Upgrade.Image_RootPath without $PLATFORM
Method 1 will work in all cases. Method 2 can also be used if the new addon to parse
Upgrade.Image_RootPath is installed on the cloud client. By resetting back the root
path to default, any image or addons common to all the platforms can be installed.

Support Details
The following is supported:
•
INI upgrades using FTP, HTTP, or HTTPS on C50LE (SP1 only), D50D (SP2 only),
D50Q (SP3 only), R50L/R50LE (SP1 only), X50m (SP1 and SP2), Z50D/Z50S (SP1 and
SP2), Z50Q (SP3 only), and Z50Qq (SP3 only) cloud client platforms in the same
network.
•
Image, Image plus addons, and addons upgrades
The following is NOT supported:
•
upgrades on the T and PC Extender cloud client platforms
•
upgrades using WDM
For example, the following is the directory structure of the image and addons under the
root path:
The Z50D cloud client will upgrade from:
…./Z50D/.…/ latest-image.raw
latest-image.raw
/addons/d irectory
*.rpm
The Z50S will upgrade from:
…./Z50S/.…/ latest-image.raw
latest-image.raw
/addons/d irectory
*.rpm
The file directory lists the names of the all the addons which are to be updated.
NOTE: No image should be put in the wyse root directory when using this method.
Mixed Environment Imaging (An Enhanced Method of Upgrading)

Directories on the Server
Administrator must create the following directories on the FTP server.
For example:
ftp or http or https://ipaddress/
…./Z50Qq/.…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
…./Z50Q/.…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
…./Z50D/.…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
…./R50/…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
…./D50Q/.…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
.…/D50/.…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
…./X50M/.…/
latest-image.raw
latest-image.raw.info
/addons/d irectory
*.rpm
IMPORTANT: …. represents any level of directories. For example the above path can be
set by the administrator as ftp://server_ip_address/xyz/Z50D/abc/qrt/.
The image for the Z50D will be in the directory ftp://server_ip_address/.../Z50D/.../ and
for the X50m the image will be in the directory ftp://server_ip_address/.../X50M/.../.
In the case of cloud clients running SP1, the SP1 image will upgrade to the latest version
after reboot and in the case of cloud clients running the SP2 or SP3 image, the Delayed
Update will download the image upon network reset or reboot and prompt the user for
the upgrade.
