To connect to the ICX30-HWC for initial configuration, you can use the Prosoft Discovery Service software to discover the module, and assign it a temporary IP address that is compatible with your existing network. The default IP address of the ICX30-HWC is 192.168.0.250/24. If your network is already on the 192.168.0.x/24 network, you should be able to access the gateway directly. You can either change your PC to be in the 192.168.0.x/24 network for initial configuration, or the most common, and proper way is to right-click on the module in the ProSoft Discovery Service, and select "Assign Temporary IP address". Then enter an unused and available address that is compatible with your network, and subnet. Load up your web browser, and type in the IP address you assigned, or the default IP address of the ICX30 to load up the default login page.
Login with the default credentials of ADMIN and PASSWORD, and you are ready to configure your ICX30!
