The C7200-I/O-GE+E does burn the bandwidth points, so with that in, you can only have 1 more "high speed" card on the other bus....<br><br><br>

Just remember to try and use the GE ports on the NPE module instead<br>
of the ones on the PCI bus if you care about performance.<br></blockquote>
On that note you can use the C7200-I/O-GE+E to get an extra gig port<br>
without using and B/W points on the PCI bus (its compatible with the<br>
G1, I'm not sure about the G2, but I can't see anything saying its<br>
not). It may work out cheaper than buying a PA-GE card as well.<br>
