The Video Viewer Window
The Video Viewer is used to conduct a KVM session with the target devices attached to a
MergePoint Unity switch using the OBWI. When you connect to a device using the Video
Viewer, the target device desktop appears in a separate window containing both the local and the
target device cursors.
The MergePoint Unity switch OBWI software uses a Java-based program to display the Video
Viewer window. The MergePoint Unity switch onboard web interface automatically downloads
and installs the Video Viewer the first time it is opened.
NOTE: Java 1.5.0_11 or later is required to launch the Video Viewer when using a Linux or Mac operating system.
NOTE: The MergePoint Unity switch OBWI does not install the Java Resource Engine (JRE). The JRE is available as
a free download from http://www.sun.com for PC users and from http://www.apple.com for Mac users.
NOTE: The MergePoint Unity switch OBWI uses system memory to store and display images within Video Viewer
windows. Each opened Video Viewer window requires additional system memory: An 8-bit color setting on the client
server requires 1.4 MB of memory per Video Viewer window. A 16-bit color setting requires 2.4 MB and a 32-bit color
setting requires 6.8 MB. Opening more than four simultaneous Video Viewer windows may affect system
performance and is not recommended. If you attempt to open more Video Viewer windows than your system memory
allows, you will receive an out-of-memory error and the requested Video Viewer window will not open.
If the device you are attempting to access is currently being viewed by another user, you will be
prompted to preempt the other user if your preemption level is equal to or greater than the other
user's preemption level. An appliance administrator can also disconnect an active user via the
Active Session page. For more information, see MergePoint Unity Switch Sessions on page 23.
