Install a DIMM

Follow this procedure to install a DIMM.

See DIMM installation rules for detailed information about memory configuration and setup.
disconnect all power
The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
Before installing a DIMM:
  1. Locate the DIMM slots and determine DIMM installation order based on DIMM installation rules.

  2. Remove the PCIe adapter installed in slot 1 if necessary (see Remove a PCIe adapter).

  3. Make sure that both retaining clips on the DIMM connector are in the open position. If not, press and open the retaining clip on both ends of the DIMM slot.

    In the case of space constraints, use a pointed tool to open the retaining clips. Place the tip of the tool in the recess on the top of the retaining clip; then, carefully pivot the retaining clip away from the center of the DIMM connector.
  4. Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

DIMMs are sensitive to static discharge and require special handling. In addition to the standard guidelines of handling static-sensitive devices:
  • Always wear an electrostatic-discharge strap when removing or installing DIMMs. Electrostatic-discharge gloves can also be used.

  • Keep each DIMM separated from one another. Do not stack DIMMs directly on top of each other during storage.

  • Keep the gold DIMM connector contacts from touching anything.

  • Handle DIMMs with care: never bend, twist, or drop a DIMM.

To install a DIMM, complete the following steps:

Align the DIMM to the connector on the DIMM slot; then, press the DIMM straight into the slot with even pressure on both ends of the DIMM until the retaining clips snap into the locked position.

Make sure that the small tabs on the retaining clips engage the notches on the DIMM. If there is a gap between the DIMM and the retaining clips, it indicates that the DIMM has not been properly installed. Remove the DIMM and reinstall it.

After installing a DIMM:

  1. Install other DIMMs if necessary.

  2. If the PCIe adapter in slot 1 was removed, install it (see Install a PCIe adapter).

  3. Proceed to complete the parts replacement (see Complete the parts replacement).

  4. Reconfigure the DIMMs if necessary.
