Overview 1-3
Port Adapter Locations on the Supported Platforms
Figure 1-4 VIP2-50 with Two Port Adapters Installed—Horizontal Orientation
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202,
slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR.
Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.
Note The I/O controller is available with or without a Fast Ethernet port. You can install both I/O
controller types in all Cisco 7200 series routers; however, when you install an I/O controller with a
Fast Ethernet port in a Cisco 7202, the system software automatically disables the port.
Figure 1-5 shows a Cisco 7206 with installed port adapters and an I/O controller with a Fast Ethernet
port. Not shown are the Cisco 7202, which has two port adapter slots, the Cisco 7204 and
Cisco 7204VXR, which have four port adapter slots, and the Cisco 7206VXR, which has six port
adapter slots. The PA-FE port adapters can be installed in any available port adapter slot in
Cisco 7200 series routers.
