ok.
That's not necessary. You can plug in the redundant SUP while the Cat6K is up and running.
It's done automatically.
If both Sups are running the same IOS the new one will be the redundant one. You can switch over by using "redundancy force-switchover"
Have a look at

processor redundancy (RPR):
?Supports a switchover time of 2 or more minutes (see Chapter 7, "Configuring NSF with SSO Supervisor Engine Redundancy").
?Supported on Supervisor Engine 720 and Supervisor Engine 2.
?Route processor redundancy plus (RPR+):
?Supports a switchover time of 30 or more seconds (see Chapter 7, "Configuring NSF with SSO Supervisor Engine Redundancy").
?Supported on Supervisor Engine 720 and Supervisor Engine 2.
?Single router mode with stateful switchover (SRM with SSO):
?Supports a switchover time of 1 or more seconds.
?Supported on Supervisor Engine 720.
?Not supported on Supervisor Engine 2.
?Nonstop Forwarding (NSF) with SSO:

Hope this helps.
