Manager software, an Avocent Session Viewer message box will appear.

Security zones
Internet Explorer restricts actions performed by the web browser, based on the security zone
membership of the web site being accessed. Each security zone typically has its own security
restrictions. The following four security zones are available in Internet Explorer:
• Trusted Sites - Web sites contained in the list of trusted sites.
• Restricted Sites - Web sites contained in the list of restricted sites.
• Local Intranet - Web sites accessed using a host name (for example, https://sun-e2-callisto).
• Internet - All other web sites, including those accessed using standard dot notation (for
example, https://10.0.0.1).
By default, the Rack Power Manager software operates correctly in the Internet, Local Intranet
and Trusted Sites security zones when accessing a hub server.
NOTE: A Rack Power Manager software hub server installed on a PC running the Windows 2003 Server will not
operate correctly in the Internet security zone.
The current security zone appears in the lower right corner of the Rack Power Manager
Explorer window.
