50 DSR Switch Installer/User Guide
Video Viewer minimum requirements
The Video Viewer requires one of the following operating systems:
• Windows 2000 Workstation or Server with Service Pack 2
• Windows Server 2003 Standard, Enterprise or Web Edition
• Window NT 4.0 Workstation or Server with Service Pack 6a
• Windows XP Home Edition or Professional
• Red Hat Enterprise Linux
The Video Viewer client requires Java when launched from Internet Explorer, Mozilla, Netscape or
Firefox browsers. The required Java version is 1.4.2_04 or later. The DSR web server
automatically downloads and installs the Video Viewer the first time it is launched.
NOTE:The DSR web server does not install the Java Resource Engine (JRE). It is available from www.sun.com
as a free download.
Launching a KVM Session
NOTE: When using a non-proxied connection, video performance over a slower network connection may be less
than optimal. Since certain color settings (such as Grayscale) use less network bandwidth than others (such as
Best Color), 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. See “Adjusting color depth” on page 54 for more information.
To launch a KVM session from the DSR Explorer:
1. Click on a device listed on the Target Devices screen. The unit overview window will appear.
2. Click the KVM Session link. The Video Viewer will launch in a new window.
Session time-out
A remote session may time-out if there has been no activity in a Session window for a specified
time. The session time-out value can be configured by using the Appliance KVM Session Settings
window. If you specify a new time-out value, it will be used the next time the DSR web server
is accessed.
To enable/disable or configure the session time-out:
1. In the side menu, click Unit Views - Appliance - Appliance Settings - Sessions -
KVM Settings.
2. Select the desired setting for the Enable Activity Timeout box.
3. If necessary, select the time limit for the inactivity timeout.
