Internet Explorer Considerations
When the Internet Explorer web browser is used, specific settings are required to enable the
Rack Power Manager software to operate correctly.
• SSL (Secure Sockets Layer) certificates - Used for secure authentication between the Rack
Power Manager software client and Rack Power Manager software hub server; see
Certificates on page 49.
• ActiveX controls - Used to display Telnet application and serial sessions.
• Security Zones - Used to control the actions that may be performed within Internet
Explorer. For example, the operation of JavaScript, which is used by the Rack Power
Manager software, is dependent on security zone settings.
• Advanced Internet options - Used for miscellaneous settings that enhance the use of the
Rack Power Manager software.
Managing ActiveX
®
controls
The Rack Power Manager software uses ActiveX controls to provide interactive content for
viewers. (The Emerson Telnet Viewer uses Java; see Java Installation on page 12 for
information.)
The functionality of the ActiveX controls is determined by the settings for the security zone
being used by the Rack Power Manager software. See Security zones on page 46.
Administrators may prevent users from installing software on their computers. In this case, the
Windows domain administrators may choose to “push” an MSI installer using a Group Policy.
This will silently install the Avocent Session Viewers without requiring the user to install the
software themselves. This will install only the viewers for Internet Explorer. The MSI file is
located on the Rack Power Manager software DVD and in the webapp/applets directory on the
Rack Power Manager server.
To download an ActiveX control on a Rack Power Manager software hub server using
Windows (all operating systems except Windows XP with Service Pack 2):
1. In a Units View window that contains target devices (see Accessing Units View windows
on page 111), click the link in the Action field or select an alternate action, if available.
You can also access a Unit Overview window for a target device and click the icon or
link for the session type.
If this is the first time the ActiveX control has been requested by the Rack Power
Manager software, an Avocent Session Viewer message box will appear, followed by a
Security Warning dialog box.
