Using the Telnet Viewer

231
The Rack Power Manager management software ships bundled with a built-in proprietary Telnet
Viewer that provides features unavailable in many other Telnet programs. These features include
configurable session properties tailored for each device, configurable user preferences for all
sessions, a scripting function for automatic device login, a macro function and a logging
function.
About the Telnet Viewer
Telnet Viewer is supported for managed PDUs only. Any other appliances will not have Telnet
sessions.
NOTE: Throughout this chapter, the term “appliance” or “managed appliance” will be used to indicate a supported
CPS appliance, CCM appliance or generic appliance that supports Telnet Viewer connections.
When a session is established with a supported appliance, the Telnet client switches to SSH
(Secure Shell) mode and opens an SSH shell to/through the appliance. The SSH shell can use any
of the Telnet client’s terminal emulations. See Security Property on page 234.
The Telnet Viewer uses the credentials provided by the Rack Power Manager software to
establish a session and will automatically accept the appliance server key. The username and
password provided by the users when they log in are authenticated by the authentication service
configured in the Rack Power Manager software.
Requirements
The Telnet Viewer is actually an applet that runs within the Java 1.5.0_02 plug-in (JRE). The
Telnet Viewer may also work with other Java versions. The Rack Power Manager software client
automatically downloads and installs the JRE (Java Runtime Environment) the first time the
Video Viewer or the Telnet Viewer is launched. See Java Installation on page 12 for information
about user interaction with the JRE installer.
