Automating updates and settings using central
conguration
This appendix describes how to set up your environment to provide your thin clients running ThinOS with automatic updates and
congurations in three simple steps.
NOTE: Dell Wyse thin clients do not require device management software. They are congured to obtain their IP address,
as well as the location of rmware and conguration instructions, from a DHCP server. However, you can use Wyse
Device Manager (WDM) or Wyse Management Suite for a more hands-on management of your thin clients. For
information about conguring your thin clients to communicate with a WDM server or Wyse Management Suite, see the
related INI parameters in Dell Wyse ThinOS INI Guide.
How to set up automatic updates and congurations
For a thin client running ThinOS to successfully access INI les and update itself from a server, you must set up the server with the
correct folder structure where the INI les and other update les are located, direct the thin client to the server, and then reboot or
start the thin client
Once DHCP and servers are congured and available, the thin client checks (at each boot up) to see whether or not any updates are
available on a predened server DHCP Option #161 species the server URL, DHCP Option #162 species the root path to the
server. If updates are available, the updates are automatically installed.
Using DHCP options
This table contains the DHCP options available for use.
