ProSAFE Wireless Controller WC7600 • Run an IP scanner application in your network to discover the IP address of the wireless controller. • Connect a serial cable between a computer and the wireless controller, and use the ipconfig command to discover the IP address of the wireless controller. Check the Internet Browser If the Ethernet cabling and IP address configuration are fine, the Internet browser might prevent you from accessing the web management interface. Check the following: • Make sure that you are using the http://address login rather than the https://address login. • Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click the Refresh button to be sure that the Java applet is loaded. • Try quitting the browser and launching it again. • Make sure that you are using the correct login information. The factory default login name is admin, and the password is password. Make sure that Caps Lock is off when entering this information. If the wireless controller does not save changes you have made in the web management interface, check the following: • When entering configuration settings, be sure to click the Apply button before moving to another tab or screen, or your changes are lost. • Click the Refresh button or Reload button in your web browser. The changes might have occurred, but the web browser might be caching the old configuration. After you have upgraded the firmware, if the browser does not display the latest features of the web management interface, clear the browser's cache, and refresh the screen.

ProSAFE Wireless Controller WC7600

•

Run an IP scanner application in your network to discover the IP address of the wireless

controller.

•

Connect a serial cable between a computer and the wireless controller, and use the

ipconfig

command to discover the IP address of the wireless controller.

Check the Internet Browser

If the Ethernet cabling and IP address configuration are fine, the Internet browser might

prevent you from accessing the web management interface. Check the following:

•

Make sure that you are using the http://address login rather than the https://address login.

•

Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using

Internet Explorer, click the

Refresh

button to be sure that the Java applet is loaded.

•

Try quitting the browser and launching it again.

•

Make sure that you are using the correct login information. The factory default login name

is admin, and the password is password. Make sure that Caps Lock is off when entering

this information.

If the wireless controller does not save changes you have made in the web management

interface, check the following:

•

When entering configuration settings, be sure to click the

Apply

button before moving to

another tab or screen, or your changes are lost.

•

Click the

Refresh

button or

Reload

button in your web browser. The changes might have

occurred, but the web browser might be caching the old configuration.

After you have upgraded the firmware, if the browser does not display the latest features of

the web management interface, clear the browser’s cache, and refresh the screen.
