Imaging solutions

ThinLinux Imaging is supported through Dell Wyse Management Suite and Dell Wyse USB Imaging Tool. For more information

about the Merlin image installation using Dell Wyse USB Imaging Tool, see the latest Dell Wyse USB Imaging Tool User's Guide

at www.downloads.dell.com/wyse.

Merlin Imaging from file server

To create and use merlin.rsp and imaging files to perform Merlin imaging on device from File Server, complete the following task:

1. Extract and copy Merlin image rsp and contents on any File Server location, for example, 2.2.x_5470_merlin.rsp and

commandsXml.xml, efi, mbr, recovery.

2. Rename the RSP file which is available in Merlin Image folder, for example, from 2.2.x_5470_merlin.rsp to

merlin.rsp.

3. Copy merlin.rsp and other imaging files to the $PLATFORM sub-directory on the FTP location. Place the image at the

correct <PLATFORM> subfolder. This is because the Merlin imaging is platform dependent.

4. Provide this path as value for MerlinUpdate.URL parameter in INI file, and if needed provide credentials for FTP server

using MerlinUpdate.Username and MerlinUpdate.Password parameters and restart the thin client. For example, if

the device model is Wyse 5470 thin client, copy the image and rsp file under ftp://<IP>/<directory>/5470/ folder,

but mention URL as ftp://<IP>/<directory>/. The Macro $PLATFORM is automatically appended.

NOTE:

Merlin imaging through File Server works only when you provide URL using INI parameters; if you provide the

same values on the Update Settings page, the imaging does not work.

After restart, Merlin image is downloaded through Delayed Update. A notification is displayed after Merlin image ready. The

Merlin imaging takes place after restart. Merlin image is not downloaded, if Delayed Update is disabled.

Limitations

● If the image version on thin client and Merlin image version on FTP server are the same, then imaging does not take place.

● Downgrading is always allowed for Merlin image. There is no force imaging for Merlin.

● Changes are not preserved after Merlin imaging.

Merlin imaging using docking station with MAPT

MAC Address Override or MAC Address Pass Through (MAPT) uses a system-unique MAC address that is entered in the

system BIOS. The unique MAC address overrides the dock or dongle MAC address every time when you connect to the

network. For more information about MAPT, see the What is MAC Address pass through? KB article at www.dell.com/support.

ThinLinux supports Merlin imaging through the Dell Docking station WD19. By default, the MAPT feature is enabled in BIOS on

the Wyse 5470 thin client. You can connect the thin client to the docking station and the network cable is connected to the

network connector (RJ45) on the docking station. This feature is applicable only for imaging using Wyse Management Suite or

using INI parameters.
