C9410 dual sup SSO - In real world.

Hello, we are working to install new C9410 chassis and would like to know if anyone has gone through a SSO event in production? The configuration we are planning is a single link to each sup.

I would specifically like to know what happens in this situation, if we cut the link to the active sup, does the backup sup kick into life with the SSO process?

I am working to get a chassis in our test environment so I can test properly, but in the meantime any real-world experiences would be great.

Thanks

That is not how it works with dual supervisor (in a single chassis). 

There are only two events (that I know of) when the second supervisor card becomes Active: 

1.  Manual Fail-Over
2.  The Primary (Active) supervisor card crashes.
