Removing the controller card:
1. Unplug the AC power cables from the module that contains the failed controller card.
2. On the module that contains the failed controller card, remove the expansion interconnect cables 2 and 6 that connect to other modules, if present.
3. Remove the Ethernet cables 4 and 5 and the USB cable 3, if present.
4. Loosen the two blue captive thumbscrews 1 on the controller.
5. Using the thumbscrews, slowly remove the controller from the module.
Installing the Base or Expansion controller card:
Important: Base and Expansion Module controller cards are keyed to fit in their respective modules only. A Base Module controller card does not fit into an Expansion Module, and vice versa. If you encounter
resistance when the controller card is installed, make sure that you are installing the controller card into
the appropriate module.
1. Position the new controller card on the alignment rails.
2. Slide the controller card slowly into the module until it is flush with the back panel of the module.
3. Tighten the blue captive thumbscrews (1) with your fingers to secure it to the module.
4. Replace the expansion interconnect cables (2 and 6), the Ethernet cable or cables (4 and 5), and the USB cable (3) that were removed previously.
5. Plug in the AC power cables.
