Case is going in tomorrow but I just wondered if anyone had actually gone through process of adding second SSM to 41/61k? There's no need to point out that CP always recommends to buy two SSMs from start. Sometimes $$ are not there.
We followed the process described in admin guide. What happens is that chassis internal network interface eth2-CIN seems to "loose" mask setting on SGM. Before adding SSM eth2-CIN is correctly turned off and has correct IP with /25 mask. After running add command and SGM reboot, interface state is active but mask is gone! So SGM is unable to communicate to anything on that CIN.

Eth1-CIN still works as expected.
As pointed out before it looks all good before we start:
