FPCs Supported by the T640 Routing Node

The T640 routing node supports the following types of FPCs:

Enhanced II FPC1—Rated at 4 Gbps full duplex
FPC2 and Enhanced II FPC2—Rated at 16 Gbps full duplex

FPC3, Enhanced II FPC3, and Enhanced Scaling FPC3—Rated at 40 Gbps full duplex

Note: If you use one or more Enhanced Scaling FPC3s in a T640 routing node that is not part of a routing matrix, each SIB in the routing node must be a SIB version B. For more information, see the T640 Internet Routing Node Hardware Guide.

T640 Enhanced Scaling FPC4—Rated at 40 Gbps full duplex; supports one PIC.

Note: If you use one or more FPC4s in a T640 routing node that is not part of a routing matrix, each SIB in the routing node must be a SIB version B. For more information, see the T640 Internet Routing Node Hardware Guide.

T640 routing nodes support the FPCs listed in Table 6. You can install any combination of the following FPCs.
