Cisco 7200 PCI Limitations

Hi all,

I have a 7200 series router (7204) here and I am trying to figure out something with it. Currently the router has a NPE-G1 card in it, giving it 3 gig interfaces but I need an extra gig interface on it to make 4.

Having a look around the available options are either get a PA-GE card that fits into one of the slots on the router or to get a C7200-I/O-GE+E (I/O controller with a gbit port on it).

The PA-GE wouldn't be suitable as looking at the Cisco site the PCI bus will limit it to 300mbit full duplex (and it goes on further to say it will be limited to approx 200mbit in best case scenario due to the design of the card) [1].

The other option left is the I/O controller. I found that you can get a port adaptor jacket card [2] 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.

Does anyone have any idea if that would be correct and the only option for another gbit port would be to get another device?

Thanks for the help
