Mixing expansion cabs?

[tconn]

I've got two Definity 11 slot chassis ties together and am having trouble finding a third. I do have the larger 18 slot chassis available which seems to interface the same... Can you mix the two together or will that break things ?

The bigger 18 slot one looks just like this:

The smaller 11 slot pair look like:

You cannot tie an 18 slot cabinet (SCC cabinet) to an 11 slot cabinet (Prologix cabinet). In order to add a third cabinet you will need another Prologix expansion cabinet.
