supervisor Redundancy in 4507r with dual Supervisor IV

I am installing a 4507r with dual supervisor IV is slots 1 and 2. When I remove the supervisor in slot 1, the supervisor in slot 2 takes over and the switch appears to remain operational. If I then re-insert the supervisor, it causes the whole chassis to reload.

Is this normal? Have I missed something obvious here?

TIA, Steve

This is not normal behavior. Can you paste more details such as software versions(a sh mod would help)
