36 Input/Output Controller Replacement Instructions

Removing and Replacing the Input/Output Controller

Note The Cisco 7200 series routers and Cisco uBR7200 series routers identify interfaces by port

adapter slot number and interface port number. Port adapter slot 0 in the Cisco 7200 series routers

and Cisco uBR7200 series routers is always reserved for the Fast Ethernet port on the I/O controller.

Therefore, the address of the Fast Ethernet port on the I/O controller (if present) in Cisco 7200 series

routers or Cisco uBR7200 series routers is always 0/0.

The Cisco 7206 router shelf identiﬁes interfaces by shelf number, port adapter slot number, and

interface port number. The shelf number is a number assigned to the router shelf during the initial

conﬁguration of the Cisco AS5800 Universal Access Server. Port adapter slot 0 in the Cisco 7206

router shelf is also reserved for the Fast Ethernet port on the I/O controller. Therefore, the address

of the Fast Ethernet port on the I/O controller (if present) in a router shelf is x/0/0, where x is the

shelf number. For information about the Cisco 7206 as a router shelf in a Cisco AS5800 Universal

Access Server, refer to the Cisco AS5800 Universal Access Server documentation listed in the “If

You Need More Information” section on page 2.

Step 1 At the privileged-level prompt, enter conﬁguration mode and specify that the console

terminal will be the source of the conﬁguration subcommands as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Step 2 Specify the Fast Ethernet port on the I/O controller interface to conﬁgure by entering the

interface fastethernet 0/0 command as follows:

Router(config)# interface fastethernet 0/0

Note In a Cisco 7206 router shelf, the interface speciﬁed in Step 2 would include a shelf

number. For example, the command interface fastethernet 5/0/0 would specify the Fast

Ethernet interface on the I/O controller (slot 0) in router shelf 5.

Step 3 If IP routing is enabled on the system, assign an IP address and subnet mask to the

interface with the ip address subcommand as follows:

Router(config-int)# ip address 1.1.1.10 255.255.255.0

Step 4 If you installed an I/O controller with the Fast Ethernet port that is equipped with an MII

receptacle and an RJ-45 receptacle, use the media-type command to specify the I/O

controller’s media type; the default is the RJ-45 receptacle. The following example

conﬁgures the MII receptacle as the media type for the I/O controller:

Router(config-if)# media-type mii

Note Use the media-type 100BaseFX command to return the media type to the RJ-45

receptacle.

Step 5 Use the full-duplex command to specify full-duplex transmission mode for the Fast

Ethernet port on the I/O controller; the default is half-duplex mode. The following

example conﬁgures full-duplex mode:

Router(config-if)# full-duplex
