If the selected device is on the same subnet as your computer, the configuration management system main page appears in your Web browser. (If a password is set on the device, enter it when prompted.)

If the selected device is on a different subnet, the Pre-IP Configuration Wizard is activated automatically. This wizard lets you configure the IP settings for the selected wireless device. It proposes IP address and subnet mask settings derived from your computer’s settings, so the selected device will then reside on the same subnet as your computer. You can accept the suggested settings or change them as required. For more information, see “Using the Pre-IP Configuration Wizard” on page 27.

The next window prompts for an administrative password to allow the new IP address to be set. When the units are shipped from the factory, there is no administration password and you should leave the password field blank. If an administration password has been set for the device, enter the password and click Next. The 3Com Web Configuration Management System main screen appears in your Web browser.
