Carefully hold the NVDIMM by the edges to avoid pressure on the components on the
NVDIMM circuit board.
3. Remove the replacement NVDIMM from the antistatic shipping bag, hold the NVDIMM by the corners, and
then align it to the slot.
The notch among the pins on the NVDIMM should line up with the tab in the socket.
4. Locate the slot where you are installing the NVDIMM.
5. Insert the NVDIMM squarely into the slot.
The NVDIMM fits tightly in the slot, but should go in easily. If not, realign the NVDIMM with the slot and
reinsert it.
Visually inspect the NVDIMM to verify that it is evenly aligned and fully inserted into the slot.
6. Push carefully, but firmly, on the top edge of the NVDIMM until the ejector tabs snap into place over the
notches at the ends of the NVDIMM.
7. Close the air duct.
Step 4: Install the controller module
After you have replaced the component in the controller module, you must reinstall the
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.
Do not completely insert the controller module in the chassis until instructed to do so.
3. Cable the management and console ports only, so that you can access the system to perform the tasks in
the following sections.
You will connect the rest of the cables to the controller module later in this procedure.
4. Complete the installation of the controller module:
a. Plug the power cord into the power supply, reinstall the power cable locking collar, and then connect
the power supply to the power source.
b. Using the locking latches, firmly push the controller module into the chassis until the locking latches
begin to rise.
Do not use excessive force when sliding the controller module into the chassis to avoid
damaging the connectors.
c. Fully seat the controller module in the chassis by rotating the locking latches upward, tilting them so
that they clear the locking pins, gently push the controller all the way in, and then lower the locking
latches into the locked position.
