After the custom sysprep is complete, the device boots to merlin operating system and the image pull operation is
performed.

NOTE:
Legacy on-premise gateway does not support the image pull operation. To use this feature, install the Wyse
Management Suite repository.
BIOS pull is not supported for Dell manufactured Windows Embedded Standard devices.
To use CA Validation for imaging, follow the below steps:
1. Ensure that the Wyse Device Agent and Merlin must be updated to the latest version on the device.
2. Install the certificates to the thin clients where the OS image pull or push operation has to be performed.
3. Enable the CA Validation from Wyse Management Suite server. For local repository, enable the CA Validation option
from the setup page, and for Wyse Management Suite repository, enable the CA Validation option from the edit
page.
NOTE: Do not install any certificates to the thin client, if you have already installed Well Known certificate to the
Wyse Management Suite server and Wyse Management Suite repository.
Thin Client should be configured with Static IP along with proper DNS servers. After installing the standard image or
SysPreped Image, the static IP is not preserved.
