Cisco 7200 Series and Cisco uBR7200 Series Ports
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.
For example, the serial port on a

Figure 8-2 shows the interface ports of a PA-T3 port adapter in slot 2 of a Cisco uBR7200 series router. The port adapter slots are numbered slot 1 and slot 2 for the Cisco uBR7246 and slot 1 for the Cisco uBR7223 (slot 0 is always reserved for the Fast Ethernet port on the I/O controller—if present). The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. Port adapters can occupy any port adapter slot; there are no restrictions.
For example, the serial port on a one-port PA-T3 serial port adapter in port adapter slot 1 has the address 1/0. (See Figure 8-2.) If the PA-T3 serial port adapter is in port adapter slot 2, this same interface port is numbered 2/0. The serial ports on a two-port PA-2T3 serial port adapter in port adapter slot 2 have the address 2/0 and 2/1.
