Attention

• Disconnect all power cords for this task.

• 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:

Figure 1. DIMM installation

1. Open the retaining clips on each end of the DIMM slot. Then, install the DIMM into the slot.
   Attention

   To avoid breaking the retaining clips or damaging the DIMM slots, open and close the clips gently.
2. Firmly press the DIMM straight down into the slot 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 slot.
   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.
