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

  • Never hold two or more DIMMs together so that they touch. Do not stack DIMMs directly on top of each other during storage.

  • Never touch the gold DIMM connector contacts or allow these contacts to touch the outside of the DIMM connector housing.

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

Before installing a DIMM:
  1. Touch the static-protective package that contains the new DIMM to any unpainted surface on the outside of the server. Then, take the new DIMM out of the package and place it on a static-protective surface.

  2. Ensure that you consider and follow the DIMM installation rules when performing the operation. See DIMM installation rules.

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.
