Thanks for the confirmation. That's exactly how I set up this ES47 M2.

The fault was in the seating of the PBM module. After re-seating it, it
did come up as an expansion box PBM with the appropriate IP address.

So, a PBM module which does not "see" it's sitting in an expansion drawer
seems to think it's an ES47 :-)
