4. Eject the DIMM from its socket by slowly pushing apart the two DIMM ejector tabs on either side of the
DIMM, and then slide the DIMM out of the socket.
Carefully hold the DIMM by the edges to avoid pressure on the components on the DIMM
circuit board.
5. Remove the replacement DIMM from the antistatic shipping bag, hold the DIMM by the corners, and align it
to the slot.
The notch among the pins on the DIMM should line up with the tab in the socket.
6. Make sure that the DIMM ejector tabs on the connector are in the open position, and then insert the DIMM
squarely into the slot.
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.
Step 4: 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.
You can use the following animation, drawing, or the written steps to install the controller module in the
chassis.
