What is the reaction of native IOS if the msfc module fails

With hyprid IOS we have the following scenario :

In the distribution layer are two C6500 connected with an etherchannel/trunk. The access switch is only connected to one distribution switch. If all is fine the access switch sends his data to the directly connected distribution switch (acitve HSRP peer) and it routes the data to the destination. If the msfc (active HSRP peer) fails the standy HSRP peer (the second Distribution Switch)comes active and the Dist. Switch with the defect msfc sends the data over the etherchannel/trunk and the other Dist. switch and he route the packets to the destination. This scenarion work fine in practice.

But what ist the reaction of native IOS ? If I remove the msfc the don´t come up !! Works the layer 2 functionality fine if the msfc fails ? Has anyone experience ?

Re: What is the reaction of native IOS if the msfc module fails

In native IOS, since the switch runs integrated IOS for both Sup and the MSFC, all operations cease if the MSFC or the Supervisor fails
