VIP Port Adapter Functions
Step 2 Attach the port adapter end of a Token Ring interface cable, or other connection equipment,
to the interface port. (See Figure 19).
Note Port adapters have a handle attached, but this handle is not shown to allow a full view of detail
on each port adapter’s faceplate.

Caution
Each 4R port adapter interface must be configured for the same ring speed as the ring to
which it is connected; either 4 or 16 Mbps. If the 4R port adapter interface is set for a different speed,
it will cause the ring to beacon, which effectively brings the ring down and makes it inoperable.
Step 3 Attach the network end of the Token Ring interface cable to the appropriate Token Ring
equipment at your site: a MAU or MSAU.
Configuring the 4R Interfaces
You can modify the startup configuration for Cisco 7000 series and Cisco 7500 series routers
through the software command interpreter called EXEC. To configure the interfaces for interface
processors, you can use either one of the setup or configure EXEC commands:
setup
configure
The setup command facility can be used after first time startup to make basic changes at any time.
The changes you make will affect only the changed elements’ current memory values that are stored
in nonvolatile memory.
The configure privileged EXEC command enables you to perform advanced configurations such as
specifying interfaces. The EXEC interprets the commands you enter and carries out the
corresponding operations. You can list available EXEC commands by entering a question mark (?).
You also can enter a question mark to obtain more information about commands. For example, enter
terminal ? to obtain a list of terminal commands or show ? to obtain a list of show commands.
