Administrator Guide

Installing the Windows IIS creates the directory C:\inetpub\ftproot, which is known as the FTP root. In the ftproot directory, create a
folder wyse and a sub folder wnos. The directory structure must read as C:\inetpub\ftproot\WYSE\wnos.
To upgrade the ThinOS rmware using FTP server:
1. Sign in to the Dell Digital Locker.
2. Download the latest ThinOS rmware and latest ThinOS packages that corresponds to your thin client model. If the rmware
and packages are in the form of a compressed self-extracting (.EXE) or zipped le (.ZIP), then extract the les.
3. Place the extracted rmware les in the C:\inetpub\ftproot\WYSE\wnos folder, and the packages to C:\inetpub\ftproot\WYSE
\wnos\pkg
on your FTP server.
4. Create a wnos.ini text le (using a text editor) in the C:\inetpub\ftproot\WYSE\wnos folder with the following INI parameters:
Autoload=2 loadpkg=1 Addpkg=TCX,FR,horizon
The option Autoload=2, ensures that the thin client uses the rmware installed on the server to upgrade, only if the rmware
on the thin client is older than the version on the server. The option LoadPkg species how to update the external packages. If
LoadPkg is not in the statement, it will inherit the value of AutoLoad.
Base package and the PCoIP package are integrated into the ThinOS rmware image. Installing the latest ThinOS rmware
image automatically installs the latest version of these packages on the ThinOS client. If you set AutoLoad=1 LoadPkg=0,
the rmware is checked, but the packages are not checked. The packages check is performed after rmware check. From
ThinOS 8.3, the external packages update mechanism is changed. Some packages are default, and loaded according to value of
LoadPkg. For example RTME. Some packages need additional parameter AddPkg to add. For example, FR, Horizon, and TCX.
The option
AddPkg is for adding packages. It depends on the value of LoadPkg. For more information about the INI parameter
usage, see Dell Wyse ThinOS INI Reference Guide.
5. Save the wnos.ini le.
6. On the ThinOS client desktop, navigate to System Setup → Central Conguration → General.
7. In the General tab, enter the IP address of the FTP server or directory. For example: 150.00.0.260/wyse. The Username eld
must have the value Anonymous and the Password eld is already pre-congured.
NOTE:
• If there is no default password or if the password is changed, then you must set your password. For example,
[e-mail].
You can also reset the thin client to factory default settings. When you reset the thin client to factory default settings,
the anonymous user is congured with the default password. However, you need to recongure the thin client.
• You can also use DHCP option tags 161 and 162 to congure the ThinOS client, le server and path information. You
must create these options on your DHCP server, congure them with the correct server information, and enable the
DHCP server scope in your environment.
8. Click OK.
9. Restart the thin client and wait until the auto-installation of packages is complete.
To verify that the thin client is upgraded, on the ThinOS desktop, navigate to System Information → General, and check the
System Version.
Firmware upgrade using HTTP or HTTPS
Ensure that you have set up a Windows PC or Server with Microsoft Internet Information Services (IIS) and HTTP or HTTPS
services installed. If you do not have the HTTP or HTTPS server installed, then refer to the article about how to setup an HTTP or
HTTPS server at support.microsoft.com.
Ensure that the web server can identify the le types used by ThinOS. Create two MIME types under IIS. The MIME's option needs
to be congured on a per site basis. On a default IIS, install:
1. Launch the IIS admin console.
2. Browse to the default website, right-click and select Properties.
3. Click the HTTP Headers tab, and in the MIME Map section, select File types → New Type.
