Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity. To
see translations of the warnings that appear in this publication, refer to the Regulatory
Compliance and Safety Information document that accompanied this device.
Note When you replace a DFC with a new DFC of the same type in the same slot, the system software will
recognize the new trunk interfaces and bring them up automatically. If you replace the existing DFC
with a new DFC of a different type, you will have to reconfigure the system. For configuration details,
refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide.
