Replacing bad SUP-720-BASE,SUP-720-3B,SUP32-GE-3B

Hi,

Is there anything that I need to check or do before installing the replacement SUP? Will the IOS from the active SUP be automatically downloaded to the replacement SUP or does manual copy have to be performed? 

Any step-by-step documentation to complete SUP replacement will be appreciated.

Thanks!

Is there anything that I need to check or do before installing the replacement SUP?

Is the chassis supporting a single supervisor line card or dual.  

If it's a single supervisor card then the most important aspect is the configuration needs to be extracted from the faulty line card and copied across to the replacement card.  The IOS needs to be the same as well to keep it consistent.  Some operators are confident even if the IOS versions are different, the configuration won't change much but I don't like taking that kind of risk(s).
