What's a "module card"?

The NPE-G1 is, of course, more expensive than a NPE-400, and the NPE-G2 
will be more expensive than a NPE-G1.  The chassis is the same, but the
G1 and G2 NPEs have on-board GigE ports that are not connected to the PCI
buses, and thus, not subject to PCI bus limitations.

Again: if you need multi-GigE line-rate, do not use a 7200 for that - it's
a very nice and very flexible workhorse, but it's not the king of raw
throughput.  Use a 3750, 6500, ASR1k, etc. for that - depending on the
feature sets you need.
