Removing DIMMs

Use extreme care when removing a DIMM. Too much
pressure can damage the socket slot. Apply only enough
pressure on the plastic ejector levers to release the DIMM
1. Observe the safety and ESD precautions listed under General Information
and Static Precautions at the beginning of this chapter.
2. Perform the steps in "Preparing Your System for Upgrade" described earlier
in this chapter.
3. Extend the server out from the rack.
4. Remove the top cover of the system chassis. See Top Cover Removal found
earlier in this chapter.
For proper cooling and airflow, do not operate the system
with the top cover removed. Always replace the top cover
before powering on the system.
5. Locate the appropriate DIMM sockets on the system board (see
Figure 4-7).
6. Gently push the plastic ejector levers out and down to eject a DIMM from its
socket. See Figure 4-10.
7. Hold the DIMM only by its edges, being careful not to touch its components
or gold edge connectors. Carefully lift it away from the socket, and store it
in an antistatic package.
Repeat the above steps to remove the remaining DIMMs.
8. Reinstall the top cover on the system chassis. See Top Cover Installation
found earlier in this chapter.
