Physical Description
Note The I/O controller without the Fast Ethernet port does not have the FE enabled LE D and the FE link LED.
The I/O controller without the Fast Ethernet port and the I/O controller that is equipped with a single
MII port do not have the MII enabled, RJ-45 enabled, and RJ-45 link LEDs.
Note An MII LINK LED is not provided on the I/O co ntro lle r be ca use t h e LED is prov ided on exter na l
transceivers that are required for connecting to the MII port on the I/O controller. Refer to the section
“Fast Ethernet Connection Equipment” section on page3-16 inChapter 3, “Installing the Cisco7204”
for Fast Ethernet MII connection requirements.
Use the showdiag 0 command to identify the I/O controller (with or without the Fast Ethernet port)
installed in your Cisco 7204 router.
Note Slot 0 in Cisco 7200 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,
the system software will not display output for the showdiag 0 command.
Note Refer to the section ““Port Adapter Slot and Logical Interface Numbering” section on page1-23 for
information about port adapter slot numbering and logical interface numbering for the Cisco 7204 router.
The following sample output from the show diag 0 command is from a Cisco 7204 I/O controller with
the Fast Ethernet port that is equipped with an MII port an d RJ-4 5 p ort:
