If using the CLI through the console port, the session will no longer be valid.  The console port on the 
new Master switch will now be activated for management.  The IP and MAC addresses of the stack will 
remain the same with the new Master.  If using a telnet session, log in using the same IP address as 
before.

In case the Master unit fails, a Standby unit is automatically configured to take place as Master.  To 
find out which unit is currently in Standby status, go to the System > Stack Management > Stack 
Summary screen.  The Standby Status column shows which unit is in Standby mode.  There are two 
standby modes:  Oper Stby and Cfg Stby.   Oper Stby is selected automatically by the Master during 
stack creation.  If the administrator decides to select a different unit to be Standby, then it is labeled 
Cfg Stby.  Both Standby modes work identically.   
 
 
In this example, unit 3 is the stack standby for the Master unit. To change the standby to a different 
unit, go to the System > Stack Management > Unit Configuration screen.
