Chapter 52 System Table 276 Configuration > System > WWW > Login Page LABEL DESCRIPTION Apply Click Apply to save your changes back to the ISG50. Reset Click Reset to return the screen to its last-saved settings. 52.7.7 HTTPS Example If you haven't changed the default HTTPS port on the ISG50, then in your browser enter "https:// ISG50 IP Address/" as the web site address where "ISG50 IP Address" is the IP address or domain name of the ISG50 you wish to access. 52.7.7.1 Internet Explorer Warning Messages When you attempt to access the ISG50 HTTPS server, a Windows dialog box pops up asking if you trust the server certificate. Click View Certificate if you want to verify that the certificate is from the ISG50. You see the following Security Alert screen in Internet Explorer. Select Yes to proceed to the Web Configurator login screen; if you select No, then Web Configurator access is blocked. Figure 457 Security Alert Dialog Box (Internet Explorer) 52.7.7.2 Avoiding Browser Warning Messages Here are the main reasons your browser displays warnings about the ISG50's HTTPS server certificate and what you can do to avoid seeing the warnings: • The issuing certificate authority of the ISG50's HTTPS server certificate is not one of the browser's trusted certificate authorities. The issuing certificate authority of the ISG50's factory default certificate is the ISG50 itself since the certificate is a self-signed certificate. • For the browser to trust a self-signed certificate, import the self-signed certificate into your operating system as a trusted certificate. • To have the browser trust the certificates issued by a certificate authority, import the certificate authority's certificate into your operating system as a trusted certificate. Refer to Appendix C on page 831 for details. ISG50 User's Guide 687
