FTP Image Updates You can configure the DHCP server to upgrade all thin clients on a DHCP network using an FTP server. Shared folders must be created on the FTP server. Use the following example and definitions to create the FTP folders. Definitions of the fields in these paths are as follows: ● : Shared directory on the FTP server where you can find the new image files ● : System-defined directory that must be present below the FTP directory on the FTP server ● /linux//image: For flashing images ● : Directory with the same name as the image version from which you wish to upgrade that you can find in the About tab (for example, S2ST0045, S2ST0045_1, etc.) ● .DD: System-defined directory that contains the image to which you want to upgrade NOTE: The image_name.DD files are case-sensitive. When a thin client boots up, it looks in the FTP image ID path on the FTP server for the matching . It then looks in the image folder for the .DD image. If the client discovers a new valid .DD image, the thin client downloads and installs the image on the thin client. If the thin client does not discover a valid .DD image, the thin client continues a normal boot up using the current image. To upgrade all thin clients in your DHCP network: 1. On the FTP server, create a new folder referencing the new image ID. (example: /linux/) 2. Create a new folder called "image" within the new image ID folder. (example: /linux//image/) 3. Add the new image file to the new "image" folder. 4. On the DHCP server, add a new scope option 180 called FTP_FORCE_OPTION with a value of TRUE. When a thin client boots up, it validates whether the FTP FORCE option is set to TRUE or FALSE. 54 Chapter 2 Installation ENWW

FTP Image Updates
You can configure the DHCP server to upgrade all thin clients on a DHCP network using an FTP server.
Shared folders must be created on the FTP server. Use the following example and definitions to create
the FTP folders.
Definitions of the fields in these paths are as follows:
●
<FTP root>:
Shared directory on the FTP server where you can find the new image files
●
<linux>:
System-defined directory that must be present below the FTP directory on the FTP server
●
<FTP root>/linux/<imageid>/image:
For flashing images
●
<imageid>:
Directory with the same name as the image version from which you wish to upgrade
that you can find in the About tab (for example, S2ST0045, S2ST0045_1, etc.)
●
<image_name>.DD:
System-defined directory that contains the image to which you want to
upgrade
NOTE:
The image_name.DD files are case-sensitive.
When a thin client boots up, it looks in the FTP image ID path on the FTP server for the matching
<imageid>. It then looks in the image folder for the <image_name>.DD image. If the client discovers a
new valid .DD image, the thin client downloads and installs the image on the thin client. If the thin client
does not discover a valid .DD image, the thin client continues a normal boot up using the current image.
To upgrade all thin clients in your DHCP network:
1.
On the FTP server, create a new folder referencing the new image ID.
(example: <ftproot>/linux/<S2ST0045>)
2.
Create a new folder called “image” within the new image ID folder.
(example: <ftproot>/linux/<S2ST0045>/image/)
3.
Add the new image file to the new "image" folder.
4.
On the DHCP server, add a new scope option 180 called
FTP_FORCE_OPTION
with a value of
TRUE
.
When a thin client boots up, it validates whether the FTP FORCE option is set to TRUE or FALSE.
