Dell ThinOS 9.x 2502, 2505 and 2508 Migration Guide

Introduction

This guide provides instructions to migrate from Ubuntu and ThinOS 9.1.4234 or later versions to ThinOS 9.x 25xx using Wyse Management Suite 4.0 or later versions.

The migration process includes the following tasks:

1. Register the device with Wyse Management Suite by automating the discovery of the Wyse Management Suite server and Group Registration Token using DHCP or DNS records.
2. Download the ThinOS firmware from the Support | Dell site—see Download the ThinOS firmware, BIOS, and application packages.
3. Configure the ThinOS 9.x-based device using Wyse Management Suite version 4.0 or later versions—see Configuring a ThinOS 9.x client using Wyse Management Suite.

  NOTE:For OptiPlex 3000 Thin Client with SFP module, the option is set to LAN or SFP NIC.

• Enable USB Boot Support: OFF
• Enable USB Wake Support: ON
• Deep Sleep Control: Disabled
