Note When you replace a DFC with a new DFC of the same type in the same slot, the system software recognizes the new
trunk interfaces and brings them up automatically. If you replace the existing DFC with a new DFC of a different type,
you must reconfigure the system. For configuration details, refer to the Cisco AS5350 and Cisco AS5400 Universal

Gateway Software Configuration Guide.

Note The Cisco AS5350 and Cisco AS5400 support one type of WAN DFC at a time. For more information about mixing
WAN DFCs, see the CiscoAS5350 and Cisco AS5400 Universal Gateway Card Installation Guide.
