> The other option left is the I/O controller. I found that you can get a port adaptor jacket card  for the 7200's that let you stick a normal interface card into the I/O controller slot (instead of the I/O controller itself).
> My main concern is if the jacket card uses its own PCI bus I am assuming the C7200-I/O-GE+E also connects via PCI which means it would be subject to the same limitations as the PA-GE.
On a 7206VXR it shows:
PCI bus mb0_mb1 (Slots 0, 1, 3 and 5) has a capacity of 600 bandwidth points.
PCI bus mb2 (Slots 2, 4, 6) has a capacity of 600 bandwidth points.
Slot 0 is the I/O module, so it seems to share the same limitations.
