Input/Output Controller Description
Note An MII LINK LED is not provided on the I/O controller because the LED is provided on
external transceivers that are required for connecting to the MII receptacle on the I/O controller. See
the “Fast Ethernet MII Connection Equipment” section on page 40 for Fast Ethernet MII connection
requirements.
Use the show diag 0 command to identify the I/O controller type (with or without the Fast Ethernet
port) that is installed in your Cisco 7200 series router or Cisco uBR7200 series router.
Note Slot 0 in Cisco 7200 series routers (including the Cisco 7206 as a router shelf in a
Cisco AS5800 Universal Access Server) and Cisco uBR7200 series routers is always reserved for
the Fast Ethernet port on the I/O controller, if present. If the I/O controller without the Fast Ethernet
port is installed in your Cisco 7200 series router or Cisco uBR7200 series router, the system
software will not display output for the show diag 0 command. If you have an I/O controller with
the Fast Ethernet port installed in your Cisco 7202 router, the system software will indicate in output
for the show diag 0 command that the Fast Ethernet port is disabled.
The following example of the show diag 0 command shows an installed I/O controller with the Fast
Ethernet port that is equipped with an MII receptacle and RJ-45 receptacle:

RJ45 EN Indicates that the Fast Ethernet port’s RJ-45 receptacle (the default media type for the Fast
Ethernet port) is initialized and enabled by the system. This LED comes on after the I/O
controller has been enabled and remains on during normal operation of the router.
This LED is disabled by the system software when the I/O controller with the Fast Ethernet
port is installed in a Cisco 7202.
RJ45 LINK Indicates that the Fast Ethernet port’s RJ-45 receptacle has established a valid link with the
network. This LED remains off during normal operation of the router unless there is an
incoming carrier signal.
This LED is disabled by the system software when the I/O controller with the Fast Ethernet
port is installed in a Cisco 7202.
Slot 0 Slot 1 These LEDs indicate which PCMCIA slot is in use by coming on when either slot is being
accessed by the system. These LEDs remain off during normal operation of the router.
