On rare occasions, we have seen the upgrade happen but the version does not change. This is because of
HTTP caching in the network. During the upgrade, HTTP requests for files on the switch get cached in
the local machine. Even though the switch is in a higher version, the management software installed is
at the old version. The workaround for this is to uninstall the Fabric/Device Manager, clear the Java Web
Start cache, and then do a clean install.

What do I do if Java Web Start hangs on the download dialog?

To make sure Java Web Start is set up to access the switch in the same way your browser is set up, follow
these steps:
Step 1 Start Java Web Start (javaws.exe or javaws). You see the Java Web Start Application Manager.
Step 2 Choose File > Preferences > General and make sure your proxy settings are correct. For example, if
you are using an HTTP proxy, set it up here.
Step 3 Choose Use Browser.
Step 4 Click OK.

How do I manually configure a browser for Java Web Start?

For browsers like Opera, certain versions of Mozilla, or Konqueror, you must manually register Java Web
Start as the helper application for the JNLP files. To do this, the data you need is:
•
•
•
•
After setting this up, you may need to restart the browser. If you see "Java Web Start not detected"
warnings, you can ignore them. These warnings are based on JavaScript, and not all browsers behave
well with JavaScript. Click on the install links to install Fabric Manager or Device Manager.
Note For Windows Users: To set up Java Web Start on *.jnlp files, select Windows Explorer > Tools > Folder
Options > File Types. Either change the existing setting for JNLP or add one so that *.jnlp files are
opened by javaws.exe. This executable is under Program Files\Java Web Start

How do I run Java Web Start from the command line?

If you cannot get your browser to run Java Web Start, you can still run Java Web Start from the command
line (javaws.exe or javaws) giving it the URL of the Fabric Manager or Device Manager on the switch
as an argument. For example, if your switch IP address is 10.0.0.1, you would use these commands to
start Fabric Manager and Device Manager:
javaws http://10.0.0.1/cgi-bin/fabric-manager.jnlp
javaws http://10.0.0.1/cgi-bin/element-manager.jnlp
