To replace the controller module hardware, you must remove the impaired controller, move FRU components to the replacement controller module, install the replacement controller module in the chassis, and then boot the system to Maintenance mode.

Step 1: Remove the controller module

To access components inside the controller module, you must remove the controller module from the chassis.

  1. If you are not already grounded, properly ground yourself.

  2. Release the power cable retainers, and then unplug the cables from the power supplies.

  3. Loosen the hook and loop strap binding the cables to the cable management device, and then unplug the system cables and SFPs (if needed) from the controller module, keeping track of where the cables were connected.

    Leave the cables in the cable management device so that when you reinstall the cable management device, the cables are organized.

  4. Remove the cable management device from the controller module and set it aside.

  5. Press down on both of the locking latches, and then rotate both latches downward at the same time.

    The controller module moves slightly out of the chassis.

DIMM socket

  1. Locate the DIMMs on your controller module.

  2. Note the orientation of the DIMM in the socket so that you can insert the DIMM in the replacement controller module in the proper orientation.

  3. Verify that the NVDIMM battery is not plugged into the new controller module.

  4. Move the DIMMs from the impaired controller module to the replacement controller module:

    Note Make sure that you install the each DIMM into the same slot it occupied in the impaired controller module.

    1. Eject the DIMM from its slot by slowly pushing apart the DIMM ejector tabs on either side of the DIMM, and then slide the DIMM out of the slot.

      Note Carefully hold the DIMM by the edges to avoid pressure on the components on the DIMM circuit board.

    2. Locate the corresponding DIMM slot on the replacement controller module.

    3. Make sure that the DIMM ejector tabs on the DIMM socket are in the open position, and then insert the DIMM squarely into the socket.

      The DIMMs fit tightly in the socket, but should go in easily. If not, realign the DIMM with the socket and reinsert it.

    4. Visually inspect the DIMM to verify that it is evenly aligned and fully inserted into the socket.

    5. Repeat these substeps for the remaining DIMMs.

  5. Plug the NVDIMM battery into the motherboard.

    Make sure that the plug locks down onto the controller module.

Step 7: Install the controller module

After all of the components have been moved from the impaired controller module to the replacement controller module, you must install the replacement controller module into the chassis, and then boot it to Maintenance mode.

  1. If you have not already done so, close the air duct.

  2. Align the end of the controller module with the opening in the chassis, and then gently push the controller module halfway into the system.

    Note Do not completely insert the controller module in the chassis until instructed to do so.
