The DIMM fits tightly in the slot, but should go in easily. If not, realign the DIMM with the slot and reinsert it.
Visually inspect the DIMM to verify that it is evenly aligned and fully inserted into the slot.
7. Push carefully, but firmly, on the top edge of the DIMM until the ejector tabs snap into place over the
notches at the ends of the DIMM.
8. Close the air duct.
Install the controller module
After you have replaced the component in the controller module, you must re-install 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 at the rear of the controller module and reinstall the
cover over the PCIe cards.
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 reinstallation of the controller module:
a. Make sure the latch arms are locked in the extended position.
b. Using the latch arms, push the controller module into the chassis bay until it stops.
c. Press down and hold the orange tabs on top of the latching mechanism.
d. Gently push the controller module into the chassis bay until it is flush with the edges of the chassis.
The latching mechanism arms slide into the chassis.
The controller module begins to boot as soon as it is fully seated in the chassis.
e. Release the latches to lock the controller module into place.
f. Recable the power supply.
