Problem Resolution
After upgrading to Management application
12.x from 11.x, unable to discover Fabric OS
devices. Error "4002" displays when trying to
discover Fabric OS devices. The Management application 12.x uses Java 1.7, which disables the use of certificates
with "weak authentication". You must update your Java certificates to resolve the issue.
Problem Resolution

Management application. To launch Element Manager from the Management application, your local system's
browser must run the Java Web Start application. To turn on Java content in the browser,

Problem Resolution
If a switch is replaced by another switch having
the same IP address but a different node WWN
while fabric tracking is on, the Management
application does not update the Product List,
Connectivity Map, or switch properties with the
new node WWN. Choose from one of the following options:
•
Turn fabric tracking off while the switch is replaced. This causes the old switch to be
removed and the new switch added.
•
After the switch is replaced, remove and re-add the fabric in the Discover Setup
dialog box.
