After upgrade of UCS C220 M3 Rack Mount Servers to 1.5(1b), you might
experience a situation where you cannot launch the KVM console. When you click
on the KVM button, there is no warning or failure message. The Java Network
Launch Protocol (JNLP) files are downloaded to the PC, but they do not trigger
the java application to open because they are not associated to it.
In order to resolve this issue, you must associate your JNLP files with
the Java Web Start application. This document shows you how to do this on MAC
and on Windows 2008 platforms.
Use these steps to resolve this issue on a MAC.
Click on the KVM icon in the UCS Cisco Integrated
Management Controller (CIMC) and locate the .jnlp file on your PC. It looks
similar to this:
As shown in this example, the file typically contains the IP
address of the Cisco UCS. In this example, the PC saves these files to the
My Downloads folder, based on the preferences in the
When you locate the file, right-click the file and choose
Open With and then select
This opens another window where you can choose the Java
WebStart.app file to these .jnlp files.
You should now be able to launch the KVM from your CIMC.
If you continue to have an issue, right-click the .jnlp file and
click Get Info.
This opens another window. Click Open with, then
click Other. Then, go to Step 3
On a Windows-based PC, the issue is the same. The Java .jnlp files run
in the Java Web Start application, which is included with the Java
In Windows 2008, click Start and navigate to
Control Panel > Java. This opens Java
Control Panel window.
Click on the Advanced tab at the top of the Java
Verify that the Java Plug-in is enabled. (Reload the
browser, if needed.)
Click the + to expand JNLP File/MIME
Association and verify that Always allow or
Prompt user is selected. If not, then make the change and
reload the browser.
You should now be able to run your KVM.
