ES47 expansion box problem

Hello everyone,
I've been tasked with setting up and testing an ES47 with an I/O Expansion
box. The components have come from different sources.
I have set up the SMC NAT box according to the docs, and am connected to
the MBM via the serial management port of the ES47.
When I power up the expansion box, I see "duplicate IP address 0xa0000001"
error messages in the MBM. When removing power from the ES47, powering up
the expansion box, connecting my laptop to the NAT box and telnetting to
10.0.0.1 I find myself in a MBM shell, which I guess s provided by the
expansion box' PBM module.
I have read that MBM and PBM are both loaded from the same firmware, so my
question at this point is: How do I get the PBM module to act like a PBM
micro (with the appropriate IP address)?
Thanks in advance for any ideas.
cu,
Martin

For an ES47 Model 4, the first 2P drawer should be set with an ID of 0, the second 2P drawer should have an ID of 1 and the first I/O drawer should be set with an ID of 3.

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 :-)

any kind of attention is to reaeat all the connectors. Ribbon cables,
memory, m/b power connectors and anything else that is unplugable.
MTBF charts tell us that connectors of any sort are the least
reliable part of any system...
