Automating updates and settings using central
conguration
This appendix describes how to set up your environment to provide your thin clients running ThinOS with automatic updates and
congurations in three simple steps.
NOTE: Dell Wyse thin clients do not require device management software. They are congured to obtain their IP address, as well
as the location of rmware and conguration 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 conguring
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 congurations
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 congured and available, the thin client checks (at each boot up) to see whether or not any updates are
available on a predened server DHCP Option #161 species the server URL, DHCP Option #162 species 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.
