3.1 How to Remove a Memory Module

Memory modules for this system are dual inline memory modules (DIMMs). Each DIMM bank must contain four DIMMs of equal density (for example, four 64-Mbyte DIMMs) to function properly. Supported DIMM configuration options are 32, 64, and 128 megabytes. See the Sun Enterprise 220R Server Owner's Guide for more information.

3.1.1 Before You Begin

Complete these tasks:

• "2.1 How to Power Off the System"

• "2.4 How to Position the System for Service"

• "2.6 How to Remove the System Cover"

• "2.8 How to Avoid Electrostatic Discharge"

DIMMs are made of electronic components that are extremely sensitive to static electricity. Static electricity from your clothes or work environment can destroy the DIMM. Always wear a grounding strap when you handle the modules.

Do not remove any DIMM from its antistatic packaging until you are ready to install it. Handle the modules only by their edges. Do not touch the components or any metal parts. Always wear a grounding strap when you handle the modules.

3.1.2 What to Do

1. Locate the memory module(s) to be removed.

2. Push the ejection lever away from the memory module and eject it from the socket.

3. Grasp the top corners of the memory module and pull it upward and out of its socket.

4. Place the module on an antistatic mat.

5. Repeat Steps 2, 3, and 4 for each memory module being removed.
