Functional Overview

The Cisco IGX 8400 Series WAN switch uses combinations of front cards and back cards (or modules)

to provide the user with greater configurational adaptability and flexibility. These modules can be

classified into functional types as follows:

• Processor cards, which contain the system controller that runs software for the switch,

• Alarm cards, which provides alarm decoding and alarm summary outputs, and

• Service cards, which allow for various information-handling services.

Processor cards are necessary for node function. Without a processor card, the switch has no software

and cannot continue with power-on.

Alarm cards are optional, and are recommended because they provide alarm summary information as an

aid in troubleshooting node and network problems.

Service cards provide a wide variety of information-handling services, including the following:

• Data (see Chapter 6, “Cisco IGX 8400 Series Data Service”)

• Voice (see Chapter 7, “Cisco IGX 8400 Series Voice Service”)

• ATM (see Chapter 8, “Cisco IGX 8400 Series ATM Service”)

• Frame Relay (see Chapter 9, “Cisco IGX 8400 Series Frame Relay Service”)
