Removing a DIMM

Use this information to remove a dual inline memory module (DIMM).

Before you remove a DIMM, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. If the compute node is installed in a chassis, remove it (see Removing a compute node from a chassis for instructions).
  3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
After you install or remove a DIMM, you must change and save the new configuration information by using the Setup utility. When you turn on the compute node, a message indicates that the memory configuration has changed. Start the Setup utility and select Save Settings (see Using the Setup utility for more information) to save changes.

To remove a DIMM, complete the following steps.

  1. Remove the cover (see Removing the compute node cover).
  2. Remove the air baffle installed over the DIMM connector.

  3. Locate the DIMM connectors (see System-board connectors). Determine which DIMM you want to remove from the compute node.
    Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the clips gently.
  4. Make sure that both retaining clips on the DIMM connector from which you are removing the DIMM are in the open position.
  5. Pull the DIMM out of the connector.
  6. If you are not immediately replacing the DIMM, install the air baffle.
    Attention: To maintain proper system cooling, do not operate the compute node without air baffles installed over the DIMM connectors.

If you are instructed to return the DIMM, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
