The Video Viewer

About the Video Viewer Window

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 containing both the local and the target device cursor. The Video Viewer window supports either a 3- or 5-button mouse.

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 the preemption level is equal to or greater than theirs. An appliance administrator can disconnect the other user via the Active Session page. For more information, see the To disconnect an active KVM session (Administrator only) procedure on page 51 in Chapter 4.
