IBM 71453RU manual Installing a memory expansion module hot-swap power supply

6.Touch the static-protective package that contains the new DIMM to any unpainted metal surface on the outside of the memory expansion module; then, remove the DIMM from the package.

7.Carefully open both retaining clips on each end of the DIMM connector.

Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and close the clips gently.

8.Turn the DIMM so that the DIMM keys align correctly with the connector.

9.Insert the DIMM into the connector by aligning the edges of the DIMM with the slots at the ends of the DIMM connector.

10.Firmly press the DIMM straight down into the connector by applying pressure on both ends of the DIMM simultaneously. The retaining clips snap into the locked position when the DIMM is firmly seated in the connector.

Note: If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly inserted; open the retaining clips, remove the DIMM, and then reinsert it.

11.Replace the system-board tray (see “Replacing the memory expansion module system-board tray” on page 91). Grasp the system-board tray on both sides (near the stop-tabs) and align the system-board tray with the chassis.

12.Slide the system-board tray forward until the tabs on the bottom of the handles touch the chassis; then, close the handles and press firmly on the release latches to snap them into the locked position.

If you have other devices to install or remove, do so now. Otherwise, go to “Completing the memory expansion module installation” on page 90.
