Central Configuration: Automating
Updates and Configurations
This appendix describes how to set up your environment to provide your thin clients running ThinOS with
automatic updates and configurations in three simple steps.
NOTE: Dell Wyse 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 for a more hands-on management of your thin clients.
For information about configuring your thin clients to communicate with a WDM server, see the
WDM related INI parameters in Dell Wyse ThinOS INI Guide.
How to Set Up Automatic Updates and Configurations
For a thin client running ThinOS 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
Once 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 DHCP Option #161 specifies the server
URL, DHCP Option #162 specifies the root path to the server. If updates are available, the updates are
Using DHCP Options
This table contains the DHCP options available for use.
Table 4. DHCP Options

not required unless the thin
client must interact with servers
