Directing the thin client to the server
After you set up the folder structure and populate it with the correct files, Dell recommends that you use DHCP to direct the
thin client to the location of the server.
To direct the thin client to the server:
Using DHCP—When using DHCP to direct the thin client to the location of the server, information about the server and root
directory is obtained from the following DHCP options:
a. 161—The server.
b. 162—Root path to the server-ftp/http/https.
● If no root path is defined, /wyse is assumed
● If a root path is defined, the additional path will be appended to the URL supplied by option 161.
c. 184—Server username to the server specified in option 161. This is optional.
d. 185—Server password to the server specified in option 161. This is optional.
NOTE:
Check-in for firmware updates is done early in the boot process. For that reason, changes in DHCP information may not be
propagated to a unit until a full boot is completed. However, you can avoid this by forcing a renewing of the DHCP lease,
which makes sure that the unit has the latest file-server location before the next firmware check.
Simply, right-click the Network Manager icon, click Enable Networking to disable it, right-click the Wireless Manager
icon, and then click Enable Networking to enable it again and the DHCP lease is renewed.
After you start your thin client, the device will look in the defined root path for the latest available image and update if
necessary. Additionally, it will check the directory file in the add-ons folder to see if any updates for installed add-ons are
defined. Add-ons that exist in the addons folder but are not listed in the directory file, will be ignored during update check-in.
