Configuring the PA-4T+ Interfaces

To continue your PA-4T+ port adapter installation, you must install the port adapter cables and conﬁgure the PA-4T+ interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted. This chapter contains the following sections:

Identifying Port Adapter Slot and PA-4T+ Interface Port Numbers, page 8-2

Shutting Down an Interface, page 8-5

Conﬁguring Timing (Clock) Signals, page 8-9

Conﬁguring Half-Duplex and Binary Synchronous Communications, page 8-12

Checking the Conﬁguration, page 8-14

If you installed a new PA-4T+ or if you want to change the conﬁguration of an existing interface, you must enter conﬁguration mode using the conﬁgure command. If you replaced a PA-4T+ that was previously conﬁgured, the system will recognize the new PA-4T+ interfaces and bring each of them up in their existing conﬁguration.

After you verify that the new PA-4T+ 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

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 a summary of the conﬁguration options available and instructions for conﬁguring interfaces on the PA-4T+, refer to the appropriate conﬁguration publications listed in the “Related Documentation” section on page vi.

Using the EXEC Command Interpreter

You modify the conﬁguration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the conﬁgure command to conﬁgure a new interface or to change the existing conﬁguration of an interface. The system prompts you for a password if one is set.
