Install a DIMM

When servicing the components in this section, unplug the AC power cords and use ESD protection.

Use this procedure to install a DIMM into a slot on a memory riser (MR) card.

Before You Begin

• For serviceability considerations, see Component Serviceability.

• For DIMM designation information, see Component Designations.

• For reference information, see Memory Riser Card and DIMM Reference.

1. Ensure that the DIMM ejector levers at both ends of the DIMM slot are in a fully open position.
2. Align the DIMM with the empty slot.

   The DIMM is keyed with a notch that needs to align with a protrusion in the DIMM slot. The keying ensures that the DIMM is installed correctly.

   
   
3. Gently and evenly push the DIMM into the slot until the ejector levers rise.

   The levers rise as the DIMM is pushed further into the slot.

   
   
4. Ensure that the levers have risen completely and have locked the DIMM in the slot.
   
5. Repeat the above steps until all replacement DIMMs are installed.

   Caution  -  Component damage. Open DIMM ejector levers can break off during the installation of the memory riser (MR) card. All populated and unpopulated DIMM slot ejector levers on the MR card must be in the fully-closed position before installing the card in the server. Ensure that all levers are closed and locked.
