Installing a memory module

Use these instructions to install memory modules in the blade server.

The following notes describe the types of direct inline memory modules (DIMMs) that the blade server supports and other information that you must consider when you install DIMMs:
  1. The following illustration shows the location of the DIMM connectors on the system board.
  2. The illustrations in this document might differ slightly from your hardware.

To install a DIMM, complete the following steps:

  1. Before you begin, read Safety and Installation guidelines.
  2. Read the documentation that comes with the DIMMs.
  3. If the blade server is installed in a BladeCenter® unit, remove it (see Removing the blade server from the BladeCenter unit for instructions).
  4. Carefully lay the blade server on a flat, static-protective surface.
  5. Open the blade server cover (see Opening the blade server cover for instructions).
  6. If an expansion unit is installed and you are installing DIMMs on the system board, remove the expansion unit (see Removing an optional expansion unit).
  7. Locate the DIMM connectors. Determine the connector into which you will install the DIMM.

  8. Touch the static-protective package that contains the DIMM to any unpainted metal surface on the BladeCenter unit or any unpainted metal surface on any other grounded rack component in the rack in which you are installing the DIMM for at least 2 seconds; then, remove the DIMM from its package.
  9. To install the DIMMs, repeat the following steps for each DIMM that you install:

    1. Turn the DIMM so that the DIMM keys align correctly with the connector on the system board.
      Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the clips gently.
    2. Make sure that the small tabs on the retaining clips are in the notches on the DIMM. If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly installed. Press the DIMM firmly into the connector, and then press the retaining clips toward the DIMM until the tabs are fully seated. When the DIMM is correctly installed, the retaining clips are parallel to the sides of the DIMM.
      Important: If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly installed. In this case, open the retaining clips and remove the DIMM; then, reinsert the DIMM.

If you have other devices to install or remove, do so now; otherwise, go to Completing the installation.
