Remove a memory module

Use this information to remove a memory module.

Before you remove a memory module, complete the following steps:
  1. Read Installation Guidelines to ensure that you work safely.

  2. Power off the corresponding compute node that you are going to perform the task on.

  3. Remove the compute node from the chassis (see Remove the compute node from the chassis).

  4. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
  5. Remove the compute node cover (see Remove the compute node cover).

Memory modules 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 memory modules. Electrostatic-discharge gloves can also be used.

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

  • Never touch the gold memory module connector contacts or allow these contacts to touch the outside of the memory-module connector housing.

  • Handle memory modules with care: never bend, twist, or drop a memory module.

  • Do not use any metal tools (such as jigs or clamps) to handle the memory modules, because the rigid metals may damage the memory modules.

  • Do not insert memory modules while holding packages or passive components, which can cause package cracks or detachment of passive components by the high insertion force.

After you install or remove a memory module, 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 the Lenovo ThinkSystem SN550 Type 7X16 Setup Guide for more information) to save changes.

To remove a memory module, complete the following steps:

Remove or install memory modules for one processor at a time.

  1. Remove the air baffle (see Remove the air baffle for instructions).
  2. Locate the memory module connectors (see System-board connectors). Determine which memory module you want to remove from the compute node.
    To avoid breaking the retaining clips or damaging the memory module connectors, handle the clips gently.
    The retaining clips for adjacent memory module connectors of processor one and processor two can not be open at the same time. Remove or install the memory modules for each processor one at a time and close the retaining clips after removing a memory module.
  3. Carefully open the retaining clips on each end of the memory module connector.

    If necessary, due to space constraints, you can use a pointed tool to open the retaining clips. Place the tip of the tool in the recess on the top of the retaining clip; then, carefully rotate the retaining clip away from the memory module connector. Pencils are not recommended, as they may not be strong enough.
  4. Make sure that both retaining clips on the memory module connector from which you are removing the memory module are in the fully-open position; then, pull the memory module out of the connector with both hands.

    To maintain proper system cooling, do not operate the compute node without an air baffle installed over the memory module connectors.
    • If you are not immediately replacing the memory module, install the air baffle (see Install the air baffle).
    • Retaining clips on the memory module connectors must be in the closed position to install the air baffle.

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