Wyse Technology 060413 manual Direct the Thin Client to the Server, Using Dhcp

56 Appendix A

Step 2: Direct the Thin Client to the Server

After you set up the folder structure and populate it with the correct files, you must then direct the thin client to the location of the server by one of the following ways:

•DHCP (see "Using DHCP")

•Manual direction (see "Manually Configuring the Server Location")

IMPORTANT: Using DHCP is strongly recommended.

Using DHCP

When using DHCP to direct the thin client to the location of the server (recommended), information about the server and root directory is obtained from the following DHCP options:

•161 - The server.

•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.

•184 - (Optional) Server username (to server specified in option 161).

•185 - (Optional) Server password (to server specified in option 161).

TIP: Check-in for configuration changes 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 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 (the DHCP lease is renewed).

TIP: For general instructions on adding DHCP Options #161 and #162, refer to Wyse Knowledge Base Solution #16132 (go to the Wyse Knowledge Base at http://www.wyse.com/kb and search for 16132).

Use the guidelines shown in Table 3 when creating and adding the DHCP options you need.
