One of the most annoying things with IDRAC6 is the Java requirement for running a remote console.  with later update versions of Java 8 you may experience a problem where during the connection setup the connection fails with a message:

connecting to virtual console server.. connection failed

It appears that this inability to connect via Java console is rooted in SSLv3 as its disabled by Java.  The fix is

Go to Java installation folder.
Open {JRE_HOME}libsecurityjava.security -file in text editor.
Delete or comment out the following line “jdk.tls.disabledAlgorithms=SSLv3”.
