| I'll repost 511.1 here with the appropriate part numbers. The short
answer is, yes H7150-AA is the PCI option for the newer boxes, DH-53Z2A-AA
is the drawer upgrade for the older boxes.

Note 511.1 PCI I/O expansion 1 of 1

You can't get the PCI I/O expansion parts now because they won't fit in
existing drawers. Here's what the scenario looks like, where Dodge is
the 4100 (4 CPUs, 8 PCI), Wrangler is the current 4000 (2 CPUs, 8 PCI),
Wrangler II is the new 4000 without I/O (2 CPUs, 8 PCI), and Durango is
the new 4000 with I/O (2 CPUs 16 PCI):

So, no, you can't ever upgrade a 4100 (Dodge)with more PCI, just the 4000.
The current box upgrades with a drawer swap. If you buy a Wrangler II
box, you can upgrade with just the I/O parts (Horse and Saddle
modules).
I think there will also be a "side-grade" part number, where you can go
from a 4100 (with a Dodge motherboard, 4 CPU capable with 8 PCI) to a
4000 (with a Durango motherboard, 2 CPU capable with 16 PCI).
