4 KVM VIDEO VIEWER
The KVM Video Viewer is used to conduct a KVM session with one or more target devices attached to one
or more KVM switches. You may optionally use KVM session profiles to control session behavior on target
devices. When you connect to a device using the KVM Video Viewer, the target device desktop appears in
a separate window. The KVM Video Viewer window supports a 3-button mouse.
4.1 Virtual Media Sessions
Virtual media sessions, which are supported on certain KVM switches, are opened from the KVM Video
Viewer.
4.2 KVM Session
The DSView™ management software, Avocent
®
Universal Management Gateway appliance and
MergePoint Unity™ KVM over IP and serial console switch use either a Java-based program or an ActiveX
applet to display the KVM Video Viewer window. The Java-based KVM Video Viewer is launched from a
Mozilla
®
Firefox
®
or Google
®
Chrome
®
based client when a KVM session is requested. The ActiveX KVM
Video Viewer is launched from a Microsoft
®
Internet Explorer
®
browser.
KVM sessions may be launched to devices from any supported KVM switch. Each KVM session will be
established using the configured encryption level. To launch a KVM session, a user must have been
assigned rights or belong to a user group which has been assigned rights to establish a KVM session.
4.3 Performance Errors
Each opened KVM Video Viewer window requires additional system memory. If you attempt to open more
KVM Video Viewer windows than your system memory allows, you will receive an out of memory error and
the requested KVM Video Viewer window will not open.
NOTE: Opening more than four simultaneous KVM Video Viewer windows may affect system
performance and is not recommended.
When using a non-proxied connection, video performance over a slower network connection may be less
than optimal. Since certain color settings use less network bandwidth than others, changing the color
settings may increase video performance. For optimal video performance over a slower network
connection, a color setting such as Grayscale/Best Compression or Low Color/High Compression is
recommended.
4.4 Java Versions
The KVM Video Viewer client requires Java when launched from Mozilla Firefox browsers. The software
client automatically downloads and installs the JRE (Java Runtime Environment) the first time the KVM
Video Viewer or Telnet Viewer is launched if the client machine did not have any supported JRE installed.
On a Windows client, it is recommended that the JRE (Java Runtime Environment) be installed in the
C:\Program Files\ location. If your system automatically installs programs in another location, you may not
