Cisco T3 Installation Manual Download Page 2

You can install a T3 DFC in any DFC slot of the universal gateway chassis.  

 

 

Note 

The Cisco AS5350 and Cisco AS5400 support only one type of WAN DFC at a time. 

Refer to 

"Troubleshooting,"

 for more information.  

 

Figure 4-1 T3 Dial Feature Card  

 

Online Installation and Removal (OIR) of the T3 DFC  

Overview  

To remove a DFC without dropping any calls or connections, you will need to take the DFC out 
of service by using the busyout command to disable the DFC. The 

busyout

 command is 

executed on a per DFC basis and will gracefully disable the card by waiting for the active 
services to terminate.  

If you have active calls on the DFC after executing the 

busyout

 command, wait for the calls to 

drop. Use the show busyout command to view the status of the termination process.  

 

 

Caution 

To avoid erroneous failure messages, remove or insert only one DFC at a time.  

 

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.
