The Video Viewer
The Video Viewer is used to conduct a KVM session with the target devices attached to the DSR
switch. When you connect to a device using the Video Viewer, the target device desktop appears in
a separate window. You will see both the local and the target device cursor. The Video Viewer
window supports either a 3- or 5-button mouse.
About the Video Viewer Window
The DSR web server software uses a Java-based program to display the Video Viewer window.
NOTE: The DSR web server 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 PC
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 theirs. An
appliance Administrator may disconnect the other user via the Active Session page. For more
information, see To disconnect an active KVM session in Chapter 4.
