If an error message displays on the console terminal, refer to the appropriate reference publication
for error message definitions. If you experience other problems that you are unable to solve, contact
a service representative for assistance.
Configuring the FSIP
If you want to change the configuration of an existing interface, you must enter configuration mode
to configure the interface. If you replaced an FSIP that was previously configured, the system will
recognize the new FSIP interfaces and bring each of them up in their existing configuration.
After you verify that the new FSIP is installed correctly (the enabled LED goes on), use the
privileged-level configure command to configure the new interfaces. Be prepared with the
information you will need, such as the following:
•
Protocols you plan to route on each new interface
•
Internet protocol (IP) addresses if you will configure the interfaces for IP routing
•
Whether or not the new interfaces will use bridging
•
Timing source for each new interface and clock speeds for external timing
For complete descriptions of configuration subcommands and the configuration options available for
serial interfaces, refer to the appropriate software documentation listed in the section "If You Need
More Information" on page 2.
Configuring the FSIP first requires privileged-level access to the EXEC command interpreter. Also,
privileged-level access usually requires a password. (Contact your system administrator, if
necessary, to obtain privileged-level access.)
Interface Port Numbering for the FSIP Serial Interfaces
Cisco 7000 series and Cisco 7500 series routers identify an interface address by its interface
processor slot number and port number in the format slot/port. Each FSIP contains either four or
eight serial interfaces. Ports are numbered sequentially beginning with interface 0. For example, the
slot/port address of the first interface on an FSIP installed in interface processor slot 0 is 0/0, and the
adjacent port on the same FSIP is 0/1.
If the enabled LED still fails to go on, remove the FSIP and try installing it in another
available interface processor slot.
•
If the enabled LED goes on when the FSIP is installed in the new slot, suspect a failed
backplane port in the original interface processor slot.
•
If the enabled LED still fails to go on, but other LEDs on the FSIP go on to indicate
activity, proceed to Step 5 to resume the installation checkout and suspect that the
enabled LED on the FSIP has failed.
•
If no LEDs on the FSIP go on, suspect that the FSIP is faulty.
•
If the enabled LED still does not go on, do not proceed with the installation. Contact
a service representative to report the faulty equipment and obtain further instructions.
Use the show interfaces or show controllers cbus command to verify the status of the
FSIP interfaces. (If the FSIP interfaces are not configured, configure them using the
procedures in the section "Configuring the FSIP.")
