Central Conguration: Automating Updates and

Congurations

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 WDM for a more hands-on

management of your thin clients. For information about conguring 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 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.
