Problem Suggested Solution
A blank screen appears 
when you click Cluster 
Management Suite or 
Visual Switch Manager 
from the Cisco Systems 
Access page.
A missing browser Java plug-in or incorrect settings could cause this 
problem.
• CMS requires a Java plug-in to function correctly. For instructions on 
downloading and installing the plug-in, refer to the release notes.
Note If your PC is connected to the Internet when you attempt to 
access CMS, the browser notifies you that the Java plug-in is 
required if the plug-in is not installed. This notification does 
not occur if your PC is directly connected to the switch and has 
no internet connection.
• If the plug-in is installed but the Java applet does not initialize, do the 
following:
–
Select Start > Programs > Java Plug-in Control Panel. In the 
Proxies tab, verify that Use browser settings is checked and that 
no proxies are enabled.
–
Make sure that the HTTP port number is 80. CMS only works 
with port 80, which is the default HTTP port number.
–
Make sure the port that connects the PC to the switch belongs to 
the same VLAN as the management VLAN. For more 
information about management VLANs, see the “Management 
VLANs” section on page 8-4.
The Applet notinited 
message appears at the 
bottom of the browser 
window.
You might not have enough disk space. Each time you start CMS, the Java 
plug-in saves a copy of all the jar files to the disk. Delete the jar files from 
the location where the browser keeps the temporary files on your 
computer.
Refer to the release notes for the required Java plug-ins.
