2. Remove the failed controller card. Refer to the instructions in this 

section.

3. Install the new controller card. You may install the new controller card 

in the same slot as the failed card or in the other controller card slot. 
For instructions, refer to “Installing the AT-SBx81CFC400 Controller 
Fabric Card” on page 112.

4. Power on the chassis.

5. Restore the configuration to the Ethernet line and controller cards by 

uploading the latest archived copy of the configuration file for the 
chassis to the new controller card. If you do not have an archived copy 
of the configuration settings of the chassis, restore the configuration 
manually.

Here are the general steps If the chassis has two controller cards and one 
cards has failed:
