Appendix A Central Configuration Using File Server

How to Set Up Central Configuration Using a File Server

Using DHCP

With the DHCP method of configuring the file server location (recommended), the thin clients obtain information about the server and root directory using the following DHCP options:

•161—Specifies the server

•162—Specifies the 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 is appended to the URL supplied by Option 161.

•184—(Optional) Specifies the server username (for the server specified in Option 161)

•185—(Optional) Specifies the server password (for the server specified in Option 161.

Tip The thin clients perform the check-in for firmware updates early in the boot process. For that reason, a unit may not receive changes in DHCP information until it completes a full boot. However, you can avoid this scenario by forcing a renewing of the DHCP lease, which ensures that the unit has the latest file-server location before the next firmware check.

Use the guidelines shown in Table A-1when you create and add the DHCP options you need.
