How do I connect my mobile panel to my connection box-

Please also see the attached pics.

We have a mobile panel connected to a S7-300 PLC via a "Connection Box Advanced" 

The connection box stopped working so it was replaced with an identical new one.

We put the two rotary coding switches to the same position as the one that broke down (01).

When we put the mobile panel to the connection box it did not start up as expected but came up with a menu for safety operation - Parameters:

"We tried selecting "E-stop button evaluated by safety relay" and to write 01 / 1 in the "Verify Box ID" Decimal box. But pressing save does not work and it does not ask for a PW.

What are we doing wrong and where do we find the password (and how do we get to a place where the PW is requested)?
