Adding redundant Supervisor Catalyst C6504

[ecare.it.cisco]

Hello,

I  would like to add a second supervisor WS-SUP32-GE-3B to a Catalys 6504 runnion IOS 12.2(33).

Which is the best procedure in order to add the second supervisor ( all supervison will have the same IOS on board) with no outage ?

Thanks

Online Insertion and Removal means that you can add the new card while the switch is up and running. This document gives some background and things to look out for:

I would be tempted to do this during a scheduled maintenance window though if possible.
